Connecting to Wi-Fi
Basic connectivity to Wi-Fi is handled by the Wi-
Fi Management Port (configured in the system
network settings). The Wi-Fi Management Port is
separate from the Wi-Fi test port. It can access
the internet, be used by other system applic-
ations, upload test results to the Link-Live web
site, and be used for remote control. The
management port also provides a more stable
network connection than the test port, which
can change connections during AutoTests or be
disconnected during Wi-Fi scanning. See Test
and Management Ports for more information.
NOTE: NetAlly testing apps use the Wi-Fi
Test Ports and Wi-Fi AutoTest Profiles to
connect to Wi-Fi networks during testing.
See Test and Management Ports for more
information.
NOTE:The AirCheck G3 can also support a
wired Ethernet port if you use a supported
external USB-to-Ethernet adapter, which
you must purchase separately. See USB
Wired Management Port for more
Home and System Interface
51
information.
To connect your AirCheck G3 to a Wi-Fi network:
1. Open the system Wi-Fi Device Settings using
either method below:
l
Open the device Wi-Fi settings from the
main Device Settings screen by tapping
the Settings icon and selecting
Network & Internet > Wi-Fi.
l
Open device Wi-Fi settings from the
Quick Settings panel by dragging down
the top Status Bar and tapping and
holding (long pressing) the Wi-Fi icon.
Home and System Interface
52
Either method opens the Wi-Fi settings
screen:
2. Ensure the Wi-Fi feature is On.
3. Tap an available Wi-Fi network in the list.
4. Enter the network's security credentials.
(Most networks only require a password, but
depending on the security settings, some
may also require a company username, EAP
type, authentication type, certificate, or
Home and System Interface
53
other credentials.)
5. Tap CONNECT.
The network you selected moves to the top of
the list, and your connection status is displayed
below its name in device and quick settings.
The Status Bar displays the Wi-Fi status icon
at the top right of the screen.
Captive Portals
When you try to connect to a network with a
Captive Portal requirement, this system noti-
fication icon appears in the top Status Bar.
Drag down from the top of the screen to open
the notification.
Tap the notification to open a web browser
window where you can enter the required
information for the captive portal. When
finished, you can access the internet through the
connected network.
Home and System Interface
54
If you are trying to connect to a network with a
captive portal, but the system notification is not
appearing, check that the Captive Portal
Detection setting is enabled in Device Settings
> Network & Internet.
Configuring for Enterprise
Security
Enterprise security requirements for
WPA/WPA2/WPA3 Enterprise now require a CA
certificate file to be imported to your tester.
Some EAPtypes also require a client certificate
and key. This procedure assumes that you are
trying to connect to an APusing WPA2-E with
PEAP.
Home and System Interface
55
l
Before You Begin
l
Import the Certificate Authority File
l
Test Wi-Fi Management Using WPA2-E with
PEAP
l
Import the Client Certificate
Before You Begin
You may depend on your IT department to
provide authorization certificates, which may be
created by a Trusted Root Authority like VeriSign
or DigiCert. If so, contact your ITdepartment for
the certificate resources. You will need:
l
CAcertificate in .pem format
l
Clients:certificates in .p12 format with
private key (EAP TLS only)
l
Common name, domain name, username,
and password for the server you to which
you want to connect.
If you have the ability to generate your own self-
signed certificates, such as a FreeRADIUSserver,
you can create these resources as needed. This
procedure uses examples generated by a
Home and System Interface
56
FreeRADIUSserver as a certificate source,
although other sources are available.
Import the Certificate Authority File
1. Copy the self-signed Certificate Authority
(CA) file (in .pem format) onto a USB thumb
drive.
2. Transfer the USB thumb drive to your
AirCheck G3, and then copy the .pem file to
the Downloads folder.
3. Open the Settings app.
4. Navigate to Security > Encryption &
credentials > Install a certificate > Wi-Fi
certificate. This opens the file picker.
5. Navigate to the Downloads folder, and
select the .pem file that contains your CA
certificate.
6. Rename this certificate (for example, CA
FreeRadius self-signed). A message
confirms that the Wi-Fi certificate has been
installed.
Home and System Interface
57
7. (Optional)Verify the CA certificate installed
correctly:
a. Tap the system BACK button to return
to Encryption & credentials.
b. Tap User credentials.
c. Verify that the name of your CAfile (for
example, CA FreeRadius self-signed) is
displayed.
8. If you are creating your own certificate:
a. Verify the common name for the
enterprise server. For example, using a
FreeRADIUS server, create a common
name of Example Server Certificate by
entering:
sudo -s
cd /etc/freeradius/certs
openssl x509 -in server.pem
-text | grep Subject |
grep CN
Output:
Home and System Interface
58
Subject: C=FR, ST=Radius,
O=Example Inc., CN=Example
Server Certificate emailAd-
dress=
admin@example.org
b. On the same server, create a user login
to access the enterprise server. For
example, with a FreeRADIUS server, you
would edit /etc/freeradius/users, locate
the section for "# The canonical testing
user", and then create the new user by
inserting 2 lines:
entuser1 Cleartext-Password
:= "randompw"
Reply-Message := "Hello, %
{User-Name}"
This creates a user login called
entuser1 with a password of
randompw.

Test and Management
Ports
The AirCheck G3 has two USBType A ports; a
single USBType Cport for charging and On-the-
Go; and two Wi-Fi radio ports.
The Wi-Fi ports give the AirCheck G3 two
network interfaces: 1) Wireless Test and 2)
Wireless Management.
General Settings and Tools
77
See the sections below for more information on
the ports. Also see Buttons and Ports and the
technical Specifications as needed.
Test Ports
Wi-Fi Test Port: The internal Wi-Fi test
adapter is a 2x2 Tri-band 802.11ax wireless
radio. (To disable, see General Settings in the
testing apps' left-side navigation drawer.)
AirCheck G3 runs Wi-Fi AutoTests, Captures,
Discovery, and other comprehensive network
analysis apps over the test . The Wi-Fi test radio
is primarily controlled by the settings in applic-
ations, especially AutoTest.
You can use the AutoTest app to set up and run
an AutoTest Wi-Fi Profile to establish a link on
the Wi-Fi test port. (By default, the AirCheck G3
starts in the Wi-Fi App passive scanning mode).
Note that the General Settings affect how you
can use the test port. (The General Settings are
accessible from the left-side navigation drawer
from most NetAlly testing apps.)
General Settings and Tools
78
The Use Wi-Fi test port option must be enabled
for the test port to function. (Enabled is the
default setting.)
General Settings and Tools

Test Profiles, which you can limit to specific
channels, APs, SSIDs, etc. See AutoTest Wi-Fi
Profile for more information.
See General Settings for more information about
all General Settings options.
Management Port
Wi-Fi Management Port: The internal Wi-Fi
management port runs on the main system's 1x1
Dual-band 802.11ac + Bluetooth 5.0 wireless
adapter, which is configured in the system
Device Settings. See Connecting to Wi-Fi to
configure this connection.
General Settings and Tools
81
The Wi-Fi management radio is set up by the
system network settings. The radio provides full
Internet access and a more stable network
connection than the Test Port, which may
frequently drop links and reconnect or resume
scanning.
AirCheck G3 can run Discovery, Ping/TCP
Connect tests, Path Analysis, and iPerf tests on
the management port, but not AutoTests or
packet captures.
USB Wired Management Port: You can use a
USB-to-Ethernet adapter to run an alternative
wired management port for your AirCheck G3.
This option allows you to set up a stable wired
connection for system updates, updating
software, communicating with Link-Live,
APuplinks, and for running basic wired tests
that can help diagnose problems that may affect
Wi-Fi devices.
NOTE: NetAlly has tested many but not all
USB-to-Ethernet adapters for compliance
with the AirCheck G3. The following
adapters are supported:

Path Analysis
See Selecting Ports below for more information.
Selecting Ports
Some of the individual NetAlly testing apps let
you select which port interface to use for tests or
analysis.
l
You may want to verify that you are getting a
reliable connection to the Internet and the
Link-Live cloud service while you are actively
using the Wi-Fi Test port to perform an
AirMapper survey. To check connectivity, you
can configure the Ping/TCP app to use the
Wi-Fi Management port to run a continuous
background ping to the Internet.
l
Each port can connect to different networks.
For example, an organization might have one
network for visitors and another for staff. You
can use the management and the test port to
check connectivity on each network without
the need to link and relink through a single
interface.

Your AirCheck G3 accesses software updates
from the Link-Live Cloud Service "Over-the-Air"
(OTA). However, you can also manually
download and install updates if you do not want
to claim your unit to Link-Live. See Manual
Updates below.
Over-the-Air Updates
For an OTAupdate, you must create an account
and "claim" your AirCheck G3 unit at Link-
Live.com. Then your AirCheck G3 can find and
download software updates. See Getting Started
in Link-Live.

Saving a Default Test App Configuration
If you find you are frequently resetting app
defaults, you can save the default con-
figuration of settings for later use within the
NetAlly testing apps. Loading a saved default
configuration within an app allows you to access
the default settings without deleting other con-
figurations. This strategy can be most useful for
Discovery Settings and Problem Settings.
1. Go to an app's settings screen.
2. With all settings set to the defaults, tap the
save button and Save As.
3. Save a default configuration with an obvious
name like "Default Profiles" or "Discovery

AutoTest Overview
AutoTest consists of three distinct testing levels:
Test Targets, Profiles, and Profile Groups. You
can create as many Profile Groups, Profiles, and
Test Targets as you need.
At the bottom level is a set of individual Test
Targets that connect to network services, such
as a web app or FTP site. A Test Target defines
parameters including type, target URL/IP
address, port number, and Pass/Fail thresholds.
More complex tests, like HTTP, allow further
AutoTest App and Profiles
175
Pass/Fail criteria, such as strings that must or
must not be contained in the HTTP body.
A Test Target can be added to and used in any
number of Profiles.
A Profile contains a series of individual network
tests. There are two Profile types: Wi-Fi and Air
Quality. Wi-Fi Profiles include connection tests
and credentials for a Wi-Fi network. Air Quality is
a passive scan of your wireless environment.
Profiles provide an automated and consistent
way to verify a network from layer 1 through
layer 7.
A Profile can be added to and used in any
number of Profile Groups.
A Profile Group is a custom-named collection of
Profiles. Profile Groups are designed to allow
further automation for testing multiple networks
or network elements with a single tap of the
START button.
A Test Target can be in any number of Profiles,
and a Profile can be in any number of Profile
Groups.

Air Quality AutoTest
Profiles
Air Quality Profiles perform a scan of the
channels in your wireless network to measure
channel utilization and interference.
Each table on the Air Quality results screen
shows the top four channels in each band with
the highest utilization, co-channel interference
or adjacent channel interference, along with the
number of APs operating on the channel.
Air Quality Profile results are described next. Tap
here to skip to Air Quality Settings.
AutoTest App and Profiles
323
The AirCheck G3 scans the 2.4-GHz band first
and displays results and then does the same for
the 5-GHz band and then the 6GHz band if
applicable.
AutoTest App and Profiles
324
Channel usage depends on the number of clients
connected to the network and the amount of
interference from devices like microwaves or
smartphones using Bluetooth. Very high
utilization or interference can affect network
performance.
Air Quality Profile Results
The image below shows a completed Air Quality
Profile test with two Warnings and two Failures
indicated by the yellow and red dots next to the
corresponding measurements.
AutoTest App and Profiles
325
AutoTest App and Profiles
326
Air Quality test gradings are based on the
Thresholds configured in the Profile's settings. In
the case shown here, the Warnings and Failures
occurred because of high Utilization and Co-
channel Interference caused by the number of
APs active on the top three 2.4 GHz channels: 1,
6, and 11.
802.11 Utilization %: Percentage of the
displayed channel's capacity used by all 802.11
WLAN devices
Non-802.11 Utilization %: Percentage of the
displayed channel's capacity being used by non-
802.11 interferers, which may be non-WLAN
sources
AutoTest App and Profiles
327
Two dashes -- indicate that no Utilization was
detected on the Channels shown.
Co-channel Interference: Interference caused by
multiple APs operating on the same channel that
AutoTest App and Profiles
328
exceed the minimum Co-channel Interference
AP Signal Level threshold in the settings. This
measurement accounts for 40-MHz and 80-MHz
channels in the 5-GHz band by counting an AP
on its primary and each secondary channel.
Adjacent Channel Interference: Interference
caused by multiple APs operating on adjacent
channels that exceed the minimum Adjacent
channel Interference AP Signal Level threshold
in the settings. This is most common in the 2.4
GHz band where channels are 5 MHz apart but
span 20 MHz. There are only three channels that
do not overlap in this band: 1, 6, 11. Larger
channel widths (e.g., 40 MHz) also affects the
adjacent channel interference counts.
Results Codes: Final status of the test (Success
or Failure)

Ping/TCP Test
App
The Ping/TCP test app runs a Ping or TCP
Connect test to your chosen target, allowing you
to monitor connectivity changes.
A Ping test sends an ICMP echo request to the
selected target to determine whether the server
or client can be reached and how long it takes to
respond. A TCP Connect test opens a TCP
connection with the selected target to test for
port availability using a 3-way handshake (SYN,
SYN/ACK, ACK).
You can open the TCP/Ping app from the Home
screen, or you can select Ping or TCP Connect
from another app, such as AutoTest or
Discovery, while viewing a device's details.

Capture
App
Packet capture is the process of recording
network traffic in the form of packets as data
streams back and forth over the Wi-Fi
connections. Packet captures can help you
analyze network problems, debug client/server
communications, track applications and
content, ensure that users are adhering to
administration policies, and verify network
security.
The capture process uses the Wi-Fi Test port.
You can open the Capture app from the Home
screen or using a link from another app, such as
AutoTest, Discovery, or Wi-Fi.

Capture Settings
The Capture app settings allow you to designate
file and slice sizes, and apply filters to capture
and analyze only certain packet types. For
example, you can create a Wi-Fi filter to capture
only packets to and from a particular AP or
client.
When you open Capture from Home and do not
configure any filters, all packets from the switch
or channel are captured. The default Wi-Fi
capture saves the packets seen on channel1.
If you open the Capture app from another
NetAlly test app, Capture filters are auto-
matically applied. Filters that can be applied
from other apps include Wi-Fi Channel, Channel
Width, and BSSID.
For example, the floating action menu on the Wi-
Fi app's BSSID Details screen below contains the
option to start a Wi-Fi Capture.

Introduction to Discovery
Discovery uses Wi-Fi to find, classify, and display
the details of network components. Information
provided by Discovery can include the following:
l
IP, BSSID, and MAC addresses
l
Device Names
l
Device Connectivity
l
SNMP Data
l
Network Problems
l
Interface Details and Statistics
Devices are discovered via ARP and Ping sweeps;
SNMP, DNS, mDNS, and netBIOS queries; and
passive traffic monitoring. Discovery classifies
each device as it is found. Up to 2,000 devices
can be reported.
The Discovery app also detects Problems with
discovered devices, including Warning and
Failure conditions.
The AirCheck G3's discovery process begins
when the unit is powered on. Once a network
Discovery App
360
connection (Wi-Fi, test or management) is
established, the active discovery process begins.
Discovery notification icons indicate the
progress of active discovery. This icon
indicates that no links are currently available for
active discovery, either because none of the
ports enabled for discovery are connected or
because AutoTest is running.
The Discovery app consistently monitors
network traffic, but the active discovery process
reruns every 90 minutes by default. You can
select a different Refresh Interval in the
Discovery Settings.
Discovery App

Select a Sort option to order the devices based
on your selected characteristic.
The selected Sort option displays in the Sort bar
above the device list, and the sort characteristic
for each device is shown under the device type
icon. In the image above, all the devices
associated with the "NSVisitor" SSID are sorted
together. Individual devices on the same SSID
are sorted numerically and alphabetically.
Tap the sort order icon to switch the sort
order between normal and reverse order.
Devices are sorted in groups. Those with
resolved names appear at the top (in normal
order), and then devices with only IPv4, IPv6,
and MAC addresses appear below, respectively.
Discovery App
371
Reversing the normal sort order reverses the
devices within the groups but does not change
the order of the groups.
Security Auditing – Batch
Authorization
Batch Authorization lets you extend filtering to
organize devices into the following security
categories:
l
Authorized: For devices approved for use on
your network
l
Neighbor: For devices owned and controlled
by neighboring organizations
l
Flagged: To give visibility to a specific device
l
Unknown: For devices that have not been
identified or classified
l
Unauthorized: For devices that should not
be on the network and may present a
security risk
l
Unspecified: Default unassigned Author-
ization status
Discovery App
372
Once categorized, it is simple to immediately
identify any new devices on the network by
filtering according to Authorization type. New
devices are identified as Unspecified.
To use the Batch Authorization feature, create a
filter that identifies the devices you want to
categorize. For example, you could filter on
SSIDs used by other offices in your building.
After you filter the list of discovered devices,
select the overflow menu.
Select Set Authorization to see how these
devices are currently categorized and the
number of devices in each category. In the
example below, 38 devices belong to other
offices and have an Unspecified authorization.
Discovery App
373
NOTE: The initial selection on this screen
defaults to the category with the highest
count. If other categories have non-zero
counts, select OK to change the author-
ization settings for all devices to the
selected category.
Discovery App
374
Select the appropriate security category. To
continue the example above, you can select
Neighbor, and then tap the OK button to
identify the Unspecified devices from other
offices as Neighbor.
You can filter the list by tapping the Filter icon
, tapping Authorization, and then tapping
Discovery App
375
See Assigning a Name and Authorization to a
Device for more information on the Author-
ization feature.
NOTE: Batch Authorization operates on the
default MAC address of a device. If a device
has multiple MACs, authorization is set only
on the default MAC address. Devices that do
not have a discovered MAC address, such as
unknown switches and off-net devices,
cannot have an authorization setting.

Routers
AirCheck G3 discovers IP routers by monitoring
traffic and querying hosts.
Discovery App
414
Switches
Switches are also discovered by monitoring
traffic and querying hosts.
Discovery App
415
Unknown Switches
Unknown switches are detected indirectly by
analyzing traffic going through surrounding
switches. The AirCheck G3 cannot identify the
switch, but it can sense where a switch is active
on the network via the device MAC addresses in
that space.
The AirCheck G3 numbers the switches as they
are discovered. (These numbers may change
each time the discovery process runs.)
The Unknown Switches Details screen shows the
number of devices connected to the switch. Tap

Printers
The AirCheck G3 identifies IP printers via the
SNMP Printer MIB and IPX printers via diagnostic
requests and queries.
Discovery App
425
SNMP Agents
SNMPagents are discovered using SNMP
queries. See SNMP Configuration.
NOTE: If AirCheck G3 cannot discover the
SNMP agents on your devices, they may be
connected to another subnet, like a man-
agement subnet. Solve this issue by adding
the subnet to Extended Ranges.
See also SNMP Details.

they appear in the main Discovery list.
Discovery App
427
AirCheck G3 displays all the information it can
gather about each tool on the Details screen.
Hosts/Clients
Other hosts and clients are discovered by traffic
monitoring and querying. If a host cannot be
identified as belonging to one of the other
categories (Switch, Router, VoIP device, etc.)
then it is categorized as Host/Client.
Discovery App
428
NOTE:A MACaddress that begins with
LocalAdm indicates that the address has
been locally randomized to prevent unau-
thorized tracking.
Discovery App
429
Device Names and
Authorization
Assigning a Name and
Authorization to a Device
The Wi-Fi and Discovery apps provide the option
to assign a Name and Authorization to any
discovered device with a MAC Address or BSSID.
Assigning a User Name and/or Authorization
status does not change any of the information
on the actual device, only how the device's
information displays on the AirCheck G3 on
which the Name and Authorization are assigned.
You only need to assign a Name and/or Author-
ization to one BSSID or MAC address for a device
with multiple addresses. Names and Author-
izations are saved in the internal authname.txt
file and remain set as the unit powers off and
on.
This feature allows you to quickly identify your
known devices and categorize them with the
following statuses:
Discovery App
431
l
Authorized: For devices approved for use on
your network
l
Neighbor: For devices owned and controlled
by neighboring organizations
l
Flagged: To give visibility to a specific device
l
Unknown: For devices that have not been
identified or classified
l
Unauthorized: For devices that should not
be on the network and may present a
security risk
l
Unspecified: Default unassigned Author-
ization status
While the Authorization statuses are designed
with these intended meanings, you can use
them however you like for your purposes.
Once set, the custom User Name is shown in
other NetAlly apps wherever device information
is displayed. The Authorization is displayed in
the Discovery and Wi-Fi apps.
You can sort and filter by the assigned Author-
ization in the Wi-Fi and Discovery apps. When a
list is sorted by Authorization (in normal sort
Discovery App
432
order), the devices with Authorizations of
highest concern appear at the top. The image
below shows a list screen sorted this way:
Applying a Name and/or Authorization
Access the Name and Authorization function
from the floating action menu on a
Discovery Details screen or a Wi-Fi Details screen
for a BSSID or Client.

name or select an Authorization. You do not
have to do both.
4. Select the radio button to assign an Author-
ization status as needed.
5. Tap OKto apply.
Once applied, the User Name and Authorization
are displayed on the Discovery Details screen.
Discovery App
437
The user-assigned name for the AP and Author-
ization for the BSSID also appear on the Wi-Fi
BSSID Details screen, as shown below.
Discovery App
438
NOTE: If different Authorization statuses are
assigned for different BSSIDs or MAC
addresses on the same device, the Author-
ization of highest concern appears on the
device's Details screens.
Changing or Clearing a User Name or
Authorization
Open the Name and Authorization dialog again
for the same BSSID or MAC address on a device to
reassign or clear the assigned User Name or
Authorization. If the Name or Authorization do
not update as expected after a few minutes, you
may have assigned them to multiple addresses
for the same device.
To view all assigned Authorizations for a device,
open the Discovery or Wi-Fi Details screen for
the device and view the Addresses or BSSIDs
screen. Then, sort by Authorization.
Discovery App
439
To reset a device's User Name and/or Author-
ization to the unassigned defaults, open the
Name and Authorization dialog, clear the User
Name field and leave it blank, and select the
Unspecified Authorization. Then, tap OK.
Revising or Importing authname.txt
Custom Names and Authorizations are stored in
the authname.txt file in the AirCheck G3's
internal storage .settings folder, accessible from
the Files app.
Discovery App
440
If desired, you can manually edit this file on the
AirCheck G3 unit, or you can create a new auth-
name.txt file on a PC and import it onto your
unit in the same file location. (You can also push
authname.txt files from Link-Live to your test
unit.)
NOTE: Your AirCheck G3 can parse ?
wildcard characters in the authname.txt file
(although * wildcard characters are not
allowed).
The default authname.txt file on your unit
contains instructions on how to format your
Name and Authorization entries:
Discovery App
441
l
Each line defines one MAC/BSSID in the
format:
MAC/BSSID, [Authorization][,
Customized Name]
l
Authorization is case insensitive and can be
one of these strings:
o
Authorized
o
Neighbor
o
Flagged
o
Unauthorized
o
Unknown
o
Unspecified (or blank)
l
You can substitute a question mark ?for a
MAC digit to match any value for that digit.
A sample authname file could look like this:

Active Discovery Ports
Tap Active Discovery Ports to select which port
Discovery uses to gather data. (Discovery uses all
of the ports by default. Uncheck them to limit
which ports are used.) Discovery runs through
the enabled ports only if an active network link
is available. See Selecting Ports for explanations
of the different ports.
Discovery App
447
Extended Ranges
The Extended Ranges screen allows you to enter
addresses of non-local subnets on which you
want the Discovery process to run. Discovery
sweeps all of the enabled Extended Ranges for
devices, whether directly connected or off-net.
The AirCheck G3 performs Ping sweeps on
subnets that are not directly connected and ARP
sweeps on connected subnets.
When the SNMP agents are on a subnet that is
separate from the hosts (PC's and servers)
subnet, additional networks must be configured
for discovery:
l
The network address of the remote subnet
you want to discover, meaning the host (PC
and server) network.
l
The network address of the switch and
router SNMP agents in the remote subnet,
e.g. a management subnet.
Configure both SNMP Credential Sets and
Extended Ranges to ensure that the AirCheck G3
always discovers management subnets,
regardless of your network port connections.
Discovery App
448
Tap the field to open the Extended Ranges list
screen.
l
Check or uncheck the boxes to include or
exclude an extended range from the current
Discovery configuration. Unchecked
Extended Ranges do not affect the default
Discovery behavior in the current
Discovery App
449
configuration, but they may be used in other
Discovery configurations (like Community
Strings and Credentials).
l
Tap any Extended Range's row to edit its
address and subnet.
l
Tap the FAB to add new extended ranges.
Active vs. Restricted Subnets
For each configured Extended Range, you can
tap the toggle button to switch from Active to
Restricted. Discovery is performed on Active
Ranges. Setting a Range to Restricted disables
the discovery process on that network or subnet,
Discovery App
450
meaning the AirCheck G3 will not communicate
with devices within the restricted range.
l
Restricted Ranges take precedence
regardless of the order in which they are
listed on the Extended Ranges screen.
l
You can Restrict a part of a configured Active
Extended Range.
l
You can also restrict a single device, whether
it is part of an Active Range or not. To enter a
single device that you do not want
discovered, enter its IP address in the
Address field, and set the Subnet Mask field
to 255.255.255.255.
Address
Tap the Address field to enter or select an IP
address range.
Discovery App
451
Tap the drop-down menu to select a previously
Discovered Subnet. The Address field is auto-
matically populated with your selection.

select an already Discovered Subnet, the Subnet
Mask is also pre-populated.
ARP Sweep Rate
Tap the ARP Sweep Rate field to select a rate
between 5 and 100 ARP requests per second.
This setting can prevent the AirCheck G3 from
shutting down ports that sense too many ARPs
being sent.
Refresh Interval
This setting controls the time between runs of
the Discovery process. By default, Discovery runs
every 90 minutes. Tap the Refresh Interval field
to select a different interval, up to 8 hours.
The Manual option turns off regular automatic
Discovery, and the process refreshes only if you
Discovery App
452
select Refresh Discovery from the main
Discovery list screen.
SNMP Configuration
The MIB (Management Information Base) of
SNMP managed devices contains information
such as device configuration, interface con-
figuration and statistics, SNMP tables (like host
resource and route tables) and VLAN details.
Through the Discovery process, the AirCheck G3
interrogates MIBs to determine the device type,
ports, connected subnets, and other data.
SNMP credentials are required to communicate
with the SNMP agents on your interconnect
devices, such as switches and routers. The
Discovery Settings allow you to enter the SNMP
community strings and credential sets the
AirCheck G3 uses to communicate with those
devices.
SNMPv1/v2
Tap the toggle button to enable or disable
SNMPv1 and v2 queries. This setting is enabled
Discovery App
453
by default and uses the Community Strings
configured in the next setting.
Community Strings
Tap this field to open the Community Strings list
screen and add, edit, or remove community
strings.
Discovery App
454
The AirCheck G3 uses the checked strings in the
order shown on this screen. If it does not receive
a response from the queried device using one
string, it sends the next string.
NOTE: This screen and others in the
Discovery settings operate much like the
AutoTest Profile Group screen.
On the Community Strings screen, you can
perform these actions:
l
Check or uncheck the boxes to include or
exclude a string from use in the current
Discovery configuration.
l

455
l
Tap the FAB to add new Community
Strings.
l
Tap any Community String's row to edit the
string and its description.
TIP: To minimize discovery time, uncheck or
delete all unused community strings, as
every failed query extends the discovery
time. You can also arrange the community
strings in the order they are used most.
SNMPv3
Tap the toggle button to enable or disable
SNMPv3 queries. This setting is enabled by
default and uses the Credentials configured in
the next setting.
NOTE: If this setting is enabled, but no
SNMPv3 credentials are configured, the
AirCheck G3 discovers the engine IDs of all
SNMPv3 agents. This is a good way to
discover if a device supports SNMPv3.
Credentials
Tap this field to open the Credentials list screen.
Discovery App
456
This screen interface works like the Community
Strings screen above. AirCheck G3 uses the
Credentials in the order shown.

Authorization Type and Password
AirCheck G3 Discovery supports two SNMPv3
Authorization types: HMAC-SHA and HMAC-MD5.
If Authorization is required, enter the
appropriate password.
Privacy Type and Password
AirCheck G3 Discovery supports four Privacy
Types: CBC-DES, AES-128, AES-192, AND AES-
256. If needed, enter the appropriate Privacy
Password.
SNMP Query Delay
This function controls how long your AirCheck
G3 waits between SNMP queries to key tables
that can cause CPU spikes in the SNMP agents,
including the ARP cache, IP address table,
routing tables, and FDB tables.
The default SNMP Query delay is No Delay. When
querying the key large tables, the AirCheck G3
asks for more data as soon as a response has
Discovery App
459
been received. You can select a 1 or 5 second
delay if needed.
Devices Discovered Through Other
Devices
By default, AirCheck G3 discovers devices from
SNMP tables of other devices. If you do not want
Discovery to automatically find devices from
SNMP tables of the device types listed here, you
can uncheck their boxes.
Discovery App
460
Routers and Subnets
When the Routers and Subnets checkbox is
enabled, any discovered routers are included in
discovery results. In addition, if Discovery has
SNMP access to a discovered router, its routing
tables are read, and the next hop routers are
added to the Discovery list. If any local subnets
are available in the routing tables, these are also
added to the Subnets list. This process
continues until all the available SNMP
credentials are tried for the added routers.
NOTES: Discovery does not sweep every dis-
covered subnet; discovered subnets are only
added to the subnets list. To perform
discovery in a specific subnet, see Extended
Ranges above.
If another site has routers you want to
discover using this process but there isn’t a
local next hop link from this site, you can
add one of the routers of that site to
discovery. The process then runs from that
router and finds the routers on that site as
well. Add the subnet of the router or just the
Discovery App
461
router’s IP address with a mask of /32 to
Extended Ranges.
Switches
When the Switches checkbox is enabled,
discovery adds any switches that it finds in
SNMP neighbor tables of other devices to the
Discovery list.
For example, when AirCheck G3 is reading the
CDP and LLDP caches of one switch, it contains
other switches. If this option is enabled, the
AirCheck G3 adds those other switches, even if
they are not in discovery ranges.
NOTE: To Discover switches at another site,
add one of the switches of that site to
Discovery Extended Ranges.
VoIP Devices
When the VoIP Devices checkbox is enabled,
discovery adds any VoIP devices that it finds in
SNMP tables of other devices regardless of the
subnet. These are usually found in the LLDP-
MED tables of the switches. Enabling the
Switches option provides the best chance of
finding all your VoIP devices.
Discovery App
462
Wi-Fi Clients
When the Wi-Fi Clients checkbox is enabled,
discovery adds any wireless clients it finds in
SNMP tables of APs and Wireless LAN
Controllers. Enabling this option along with
Switches provides best chance of finding all Wi-
Fi clients.
NOTE: Enabling Wi-Fi Clients here may
cause Wi-Fi devices to show in Discovery
that do not appear in the Wi-Fi analysis app
because Wi-Fi analysis only shows what it
detects on wirelessly transmitted packets.
Virtual Machines
When the Virtual Machines checkbox is enabled,
discovery adds any virtual machines that it finds
in SNMP tables of other devices. These are
usually found in the ESX host > SNMP tables.
Adding the subnets of your ESX hosts to
Extended Ranges helps with finding your virtual
machines.
Device Health Interval
Discovery automatically runs a set of network
health tests to search for network Problems,
Discovery App
463
such as high utilization, discards, or errors on all
discovered interfaces and device resources.
The selected time Refresh Interval is the
minimum time between each run of the Device
Health tests. Tap the field to disable Device
Health testing or to change the interval from the
default of 10 minutes to 30 or 60 minutes.
Disabling the Device Health testing affects the
types of Problems that Discovery can detect.
See also Problem Settings.
Auto AP Grouping Rules
This feature allows you to adjust the AP
Grouping Rules that control how the AirCheck G3
groups BSSIDs with their Access Points, such
that they are grouped appropriately for your AP
types and environment.
For example, if BSSIDs from different APs are
being grouped together inaccurately, you can
disable the rule that is causing the grouping. If
Discovery App

Name
If desired, enter a custom name for a default or
new rule. If you intend to use a Prefix filter, a
best practice would be to name the rule with the
AP manufacturer's name.
Prefix filter
Use the Prefix filter to create a rule for a specific
AP manufacturer's BSSID scheme, meaning a
rule for just one AP manufacturer prefix. The
default rules all contain a default Prefix filter of
000000-000000.
If a Prefix filter is non-zero, its second and third
bytes are compared to discovered BSSIDs before
the Filter mask (described below) is applied.
These two bytes must match exactly, or the two
BSSIDs are not grouped together. This behavior
allows you to specify a fairly open Filter mask,
because the mask applies only to one man-
ufacturer.
For example, you could have Cisco APs with
BSSIDs that all start with b83861. By specifying a
Prefix filter of 003861-000000, you limit the
grouping rule to just those APs.

Wi-Fi Analysis and
Discovery
Wi-Fi Analysis uses the Wi-Fi Test Port to scan
the channels and acquire information about
your wireless networks. If the Wi-Fi Test Port is
linked (for instance after running a Wi-Fi
AutoTest Profile), the port unlinks and resumes
scanning when you open the Wi-Fi Analysis app.
When AirCheck G3 links to a network, Discovery
can obtain information from network layers 3
and above, such as IP addresses, Protocols, and
SNMPdata.
Therefore, the information Wi-Fi Analysis is able
to display also depends on configured Discovery
Settings, such as SNMP Community Strings and
Credentials, Active Discovery Ports, Extended
Ranges, and Device Health testing.
Wi-Fi Analysis App
478
The Wi-Fi app's navigation drawer displays a
real-time count (in parentheses) of each wireless
component AirCheck G3 has detected. Tap an

Path Analysis
App
Path Analysis traces the connection points,
including intermediate routers and switches,
between the AirCheck G3 and a destination URL
or IP address. You can use Path Analysis to
identify issues such as overloaded interfaces,
overloaded device resources, and interface
errors. It also shows how devices within your
network (and off-net devices) are connected to
each other along a path.
All switches are pre-discovered through SNMP
queries. When the measurement is complete,
AirCheck G3 shows the number of hops to the
destination device. A maximum of 30 hops can
be reported.
567
AirCheck G3 User Guide
Back to Title and Contents
Introduction to Path
Analysis
Path Analysis combines Layer 3 and Layer 2
measurements.
The Layer 3 measurement combines the classic
Layer 3 IP (UDP, ICMP, or TCP) traceroute
measurement with a view of the path through
the Layer 2 switches.
The Layer 2 measurement discovers switches
between the router hops by looking for the
routers' MAC addresses in the switch forwarding
tables by sending SNMP queries to all
discovered switches. The switches found in the
path are displayed between the router hops
when the measurement finishes.
Path Analysis is most effective when you have
configured the Discovery app with SNMP
credentials. See SNMP Configuration in the
Discovery Settings topic to learn how.
Path Analysis App
568
Path Analysis Settings
The Path Analysis source device is always your
AirCheck G3. The default destination is www.-
google.com.
Populating Path Analysis from
Another App
Like other AirCheck G3 testing apps, when you
open Path Analysis from another app, like
Discovery, the address of the network
component you were viewing in the previous
app is pre-populated as the Path Analysis

Survey Mode
Tap Survey Mode to select the Wi-Fi data
collection method that best suits your Wi-Fi
environment and survey data collection require-
ments:
1. Auto Sampling (Passive) is the default and
preferred way to perform a survey.
AirMapper automatically records data (at
the interval specified with the Auto
Sampling Period setting) between two
points that you choose. This simplifies data
sampling and can prevent oversampling. For
example, if your survey includes a long
hallway or open space, you can take a
manual sample measurement at one end of
the area, go to the other end, and then take
AirMapper™ App
595
another measurement. AirMapper fills in the
line between the two measurements with
automatic measurements made at the
sampling period. See Collecting AirMapper
Data for more information.
2. Current Scan (Passive) Passive
surveysallow immediate data collection
based on the most recent APbeacon seen
from each BSSID. APBSSIDs age out after
140 seconds, and Wi-Fi clients age-out after
4 minutes.
3. Scan Once (Passive) is more precise but
more time-consuming. When a point is
selected, all the BSSID information is
cleared, and the unit acquires a single scan
of the selected channels for the selected
dwell time. This gives an exact
measurement. However, in congested envir-
onments any beacons not seen during the
dwell time are not included in that sample
point.
4. Connected (Active) collects data from the
linked connection of the Wi-Fi Test port.
NOTE:Selecting this method disables the
AirMapper™ App

(Enabled only when Override Bands and
Channels is enabled.) Tap Wi-Fi Bands and
Channels to open a list of frequency bands.
Then tap the frequency band to open a menu to
select specific channels to use for that band. See
the General Settings for additional information.
AirMapper™ App
598
NOTE: Selecting a subset of channels and bands
lets you exclude scans of unneeded channels
from the survey. This improves survey
performance and reduces the amount of data
collected.
Changing Settings after Starting
You can reopen the AirMapper settings to
change the Floor Plan > Dimensions or Signal
Propagation size after starting your survey.
Existing data points are retained on the map
unless you select a different Floor Plan.
AirMapper™ App
599
NOTE: NetAlly does not recommend that you
change the band, channel, or dwell time settings
after you have started a survey. The survey
results for the multiple settings can create
confusing or less reliable results. If you wish to
do so and if the Override Bands and Channels
setting is enabled, you can use the AirMapper
Settings to make changes after you have started
your survey. If the Override Bands and Channels
setting is not enabled you must use the General
Settings to make changes.
Hidden SSIDs and APs
For any [Hidden] APs or SSIDs at your site that
you want detected during a survey, NetAlly
recommends creating and enabling a Wi-Fi
Profile in the AutoTest app, configured with the
appropriate credentials. Otherwise, AirMapper
detects the BSSIDs associated with hidden
devices but may not determine their APs/SSIDs.

2. Tap START to begin the survey. If you did
not start the AutoTest profile or if the test is
still in progress, a message displays at the
bottom of the screen, and the survey cannot
start.
3. Collect data as you would a passive survey,
as described above.
o
If the connection is lost (such as by
roaming out of range or a signal
blockage), the link notification changes
to an X. AutoTest continuously tries to
reconnect to the SSID.
Survey points taken during this unlinked
time are displayed in yellow to indicate
AirMapper™ App
608
areas where there is not coverage for
that SSID.
o
You can check the Wi-Fi connection in
