LinkRunner AT 1000/2000
Network Auto-Tester
I. INTRODUCTION
LinkRunner AT 1000/2000 Network Auto-Tester enables
quick verification of Ethernet copper and fiber (2000 model
only) cables as well as network connectivity and availability.
The tester also identifies the network device to which it is
connected, measures and displays PoE voltage and
configuration, generates reports, and serves as a packet
reflector for performance tests conducted with other
NETSCOUT products.
The included Link-Live Cloud Service provides automated
reporting and options for organizing test results while the
LinkRunner Manager application allows you to save custom
test profiles, manually load results, and update firmware.
Link-Live Cloud Service
The Link-Live Cloud Service is a free, online system for
collecting, tracking, and organizing your test results, which
are automatically uploaded to Link-Live once configured. 
See “Link-Live Cloud Service,” page 11.
LinkRunner Manager
LinkRunner Manager is a Windows PC application for
updating your LinkRunner AT software, creating profiles,
storing results, and generating reports. You can install
LinkRunner Manager from the included CD or download the
app from Link-Live at https://app.link-live.com/downloads.

To charge the Li-ion battery, connect the AC adapter to the
battery connector (see Figure 1 number ). You can use the
tester while you charge the battery.
When the tester is off, the battery charges in approximately 3
hours. The Li-ion battery life is approximately 6 hours during
typical operation. The AA battery life is approximately 3
hours.
An icon in the upper-left corner of the screen shows the
battery status .

Common Questions LinkRunner AT Can Answer
9
IV. COMMON QUESTIONS 
LINKRUNNER AT CAN ANSWER
First, connect an RJ-45 or fiber cable (2000 model only) from
the network hub or wall plate to the LinkRunner AT RJ-45 LAN
or fiber port. Check the following list of questions and
associated answers to see how LinkRunner AT can help you
get the job done.
Is this a good RJ-45 Ethernet cable?
Use Cable testing and the built in wiremap for patch cables,
or an external WireViewTM Office Locator.
Am I receiving a good fiber signal?
Connect to your network via a SFP adapter and validate the
signal strength and link in the Switch screen.
Where does this RJ-45 cable go?
Use the Cable test toner function, Switch > Flash Port
function, or Switch discovery protocol.
Is this cable hooked up to anything?
Select Switch to identify an open cable, an active link, or an
un-powered network device.
Does this RJ-45 port support PoE?
Use Tools to specify the desired PoE power class and use
Switch or AutoTest to verify the power under load up to
25.5 W (802.3at).
What speed/duplex is this device configured for?
Use Switch to check the advertised and actual speed/duplex.
Additionally, use Tools to test for manual (non-Auto
Negotiated) speed/duplex.
Can I see traffic from this connection?
Observe the utilization LED blinking to see network traffic.
Can I connect in a MAC access control environment?
Use Tools > VLAN/MAC/Proxy Configuration to specify a
user defined MAC address.
Do I have network connectivity?
Select AutoTest to validate key network services (DHCP, DNS,
Router).
Can I get an IPv4 DHCP address?
Select AutoTest. Select DHCP (or enter a static IP address) in
the Tools > IP Configuration menu.
Can I get an IPv6 address?
Enable IPv6 in Tools > IP Configuration. Use AutoTest to
observe the acquired IPv6 link-local and global address.

Common Questions LinkRunner AT Can Answer
10
Can I PING?
Select AutoTest. Configure an address to Ping under Tools >
AutoTest Configuration.
Can I verify application connectivity?
Select AutoTest. Configure an address and application port
(e.g. port 80 for web/HTTP) under Tools > AutoTest
Configuration.
Can I use it for throughput testing?
Use the Reflector tool (setup under Tools - only available on
LinkRunner AT 2000).
Can I connect to an 802.1X port?
Use the Tools > Connect Configuration screen to enable
802.1X. Also, use the LinkRunner Manager PC application
(select Tools > General Information to enable 802.1X and
set up security).

Link-Live Cloud Service
11
V. LINK-LIVE CLOUD SERVICE
This online service, once set up, automatically uploads and
saves results from the LinkRunner AT.
In the Link-Live Cloud Service, you can view comments added
to test results on the LinkRunner AT unit and add new
comments to completed tests. These comments and other
test characteristics can be searched and filtered to display
only specific data, which can aid in troubleshooting. You can
also customize folders in which to organize and categorize
your test results by location, event, job, or other information.
Link-Live can then generate and print reports for
communicating job status or documenting completion.
To start, create a user account at Link-Live.com and sign in.
After creating a new account, you will be prompted to Claim
your first testing device. Follow the on-screen instructions to
claim your LinkRunner AT.
Once your LinkRunner AT is claimed in Link-Live, and you
have configured it to upload to Link-Live rather than save to
internal memory, test results upload automatically as soon
as you connect to the internet.
The Cloud icon displays in the upper right corner of the
LinkRunner AT’s test results screens (such as AutoTest)
when the tester is able to upload to Link-Live Cloud Service.
If no connection is available, the Tester will queue up to 10
tests before overwriting previous results.
You can also configure uploading and notification settings on
the Link-Live Cloud Service web site. For more information
about Link-Live, click Support > Questions at the top right of
the Link-Live web page at Link-Live.com.

Setting Up the Tester

VI. SETTING UPTHE TESTER
To change settings on the tester, select Tools from the home
screen.
Figure 4. Tools Menu
IP Configuration
Select Tools > IP Configuration.
Figure 5. IP Configuration Screen
This screen allows you to enter an IPv4 address or use a
DHCP address (default). It also allows you to enable IPv6
addressing (2000 model only). LR-AT uses the IP address
during AutoTest. During AutoTest, the LR-AT is required to
connect to the network for Ping and TCP Connectivity testing.
At no other time does the LR-AT connect to the network using
IP addressing. This applies to the Switch and Cable test
screens.

Setting Up the Tester

VLAN/MAC/Proxy Configuration
Select Tools > VLAN/MAC/Proxy Configuration.
Figure 6. VLAN/MAC/Proxy Configuration Screen
This screen allows you to enable and enter the VLAN ID and
its Priority level. Un-check the VLAN check box to disable the
VLAN capability.
You can also enable and enter a user defined MAC address.
Un-check the Enable User Defined MAC check box to revert
the LinkRunner AT back to the factory default MAC address.
This screen also contains Proxy settings.
NOTE: To access the Proxy Configuration, your
LinkRunner AT must have firmware version 2.5.3 or later,
which also requires you to download and update
LinkRunner Manager software to version 1.0.9.1112.
To configure with your network’s Proxy settings:
1 Select Address, enter your proxy server address, and
save (F2).
2 Select Port, enter your proxy server port number, and
save (F2).
3 If required, select User, enter your User ID, and save (F2).
4 If required, select Password, enter your proxy password,
and save (F2).
LinkRunner AT can now be claimed and then send test results
to Link-Live.com via the configured proxy server.
