Navigation
Home screen – Displays link, speed/duplex, length, utilization, security authentication, connection, and
wire map information.
PING screen – Displays (scrolling from left to right) a Tx/Rx summary of all devices to the right which
will include: the Router, DHCP, DNS, and each user configured IP address.
LLDP (IEEE), EDP (Extreme Networks), CDP (CISCO) screen – Displays the switch address (MAC or IP),
switch name, slot/port, VLAN ID (optional), and VOIP VLAN Reply ID (optional).
Power over Ethernet - Displays the Power over Ethernet voltage levels for each Ethernet connector
pin.
Flash Hub Port screen – Causes the LinkRunner Duo to continuously link and unlink at a selected
speed. This is useful when identifying which port LinkRunner Duo is connected to. Use the
LLDP/EDP/CDP test first if your network supports it.
Reports screen – Allows you to save up to four reports. Each report contains a summary of the Home
screen, PING screen, and LLDP, EDP, CDP screen. The reports must be viewed on the LinkRunner
Connect PC application.
Packet Reflector Screen (optional feature) – Enables packet reflector mode, which allows the
instrument to be used as a remote device for the Fluke Networks MetroScope™ Service Provider’s
network performance tests. Use the Configuration screen to set up the parameters.
Toner screen – Generates a digital tone (IntelliTone) signal , or two different analog tone signals
(400 Hz) and (1 KHz) to be used with the Fluke Networks IntelliTone product or common
analog probes.
Configuration screen – Multiple menu functions are accessed in this screen. The configuration screen
accesses: the LinkRunner Duo version information; Fiber SFP adapter information; user preferences;
enter up to 10 PING addresses; enable options; edit or delete reports; configure and enable packet
reflector mode; select a VLAN; enable or disable 802.1X security; perform a firmware update; or exit
back to the Home screen. See the Configuration section for details.

Is this an active RJ45 LAN port?
Note: If both the RJ45 LAN and 1000BASE-X fiber ports are connected to your network, LinkRunner Duo will try to
link to the RJ45 LAN port first. If link has been established over fiber and you connect also to the RJ45 LAN port, no
change in link will occur.

Home – Link Information and Wire Map functions
Note:
Wire Map and PoE detection do not apply when connecting to your network through the 1000BASE-X SFP fiber adapter.
The Home screen displays link or Ethernet wire map information depending on
the connection. If the RJ-45 Ethernet cable is connected from the RJ-45 LAN
port to your network, LinkRunner Duo will display link information which will
include link, speed/duplex, cable length to the network connection, and
network utilization. If a fiber cable is connected from the 1000BASE-X SFP fiber
port to your network, everything mentioned above is displayed, minus the
cable length measurement, plus a dBm fiber signal strength measurement.
If LinkRunner Duo detects PoE, this screen will display PoE information. Notice
the PoE label and wire pairs are displayed.
This screen is displayed if LinkRunner Duo has successfully linked, and 802.1X
has been detected and authenticated.
Note: Cable information is obtained through the RJ-45 LAN port only.
Good cable
Unknown cable
Split cable
Shorted cable
Open cable - If the RJ-45 Ethernet cable is not connected to a WireviewTM
Office Locator, or to your network (open cable), LinkRunner Duo will display
cable information.
If the RJ-45 Ethernet cable is connected from the RJ-45 LAN port to a WireviewTM
Office Locator, LinkRunner Duo will display wire map information which
includes length, open, shorts, and wire pair mapping.

The PING function contains several screens that are accessed by scrolling to the right. The first PING screen displays a
summary showing a count for total number of packets transmitted and replies received. As you scroll to the right,
the PING provides details on the Router, DHCP, DNS and up to 10 additional IP addresses are displayed as shown
below.

The 10 additional IP addresses are entered in the Configuration screen, or by using the LinkRunner Connect PC
application and transferring them via a provided USB cable to the LinkRunner Duo.
Note: If configured for DHCP, and the DHCP server cannot be found, PING will display .

Duplicate IP addresses found is shown as follows:
See the configuration for procedures to set up PING IP addresses.
LLDP, CDP, EDP
The LLDP, CDP, EDP function displays the switch address (MAC for LLDP, IP for
CDP, MAC for EDP), switch name, slot/port information (if available), and VLAN
information (if available ) such as VLAN ID and VOIP VLAN Reply ID. The first
switch discovered is displayed first. Up to 5 switches can be displayed and are
accessed by scrolling to the right. If none can be discovered, use Flash Hub Port to
discover the switch slot/port information.
PoE displays which pins/wires have PoE (power over Ethernet) voltage and their
voltage levels. 0V indicates ground pin/wires.
Flash Hub Port
The Flash Hub Port function will negotiate link and then unlink at a selected
speed allowing you to locate a corresponding switch slot/port by its flashing LED.
The slide bar determines the speed. To the right is faster (rabbit); to the left is
slower (turtle).
IntelliTone
This function can be paired up with the Fluke Networks IntelliToneTM Probe or an
analog probe. It allows you to use LinkRunner Duo as the tone generation device
along with the IntelliTone Probe to trace connections using either a digital tone
(Fluke Networks IntelliToneTM), or two different analog tones.

Reflector Mode (optional feature)
Enables packet reflector mode, which allows the instrument to be used as a
remote device for the Fluke Networks network performance tests. Use the
Configuration screen to set up the parameters.
Saving Reports
Allows you to save the report summary information which contains the current
Home screen, PING screen, and LLDP, EDP, CDP screen. Saved reports must be
viewed on a PC using the LinkRunner Connect PC application. Make sure
LinkRunner Duo is connected to a PC using the provided USB cable.
To save a report: Highlight the Report symbol and press the selection button. Use
the left/right arrow keys to select which report number/name to save the
summary information to (default names are Report01 – Report08; which can be
edited from the configuration screen), and press the selection button again.
report empty report saved
Configuration
The Configuration screen accesses multiple functions: It will display the LinkRunner Duo serial number, MAC address,
and version information. It allows you to enable 802.1X security; change the cable length measurements from feet to
meters, set the power off timeout, use DHCP or manually enter the LinkRunner Duo IP address, enter up to 10 IP
addresses to PING, and enable options.
To avoid a duplicate IP address on your network, use DHCP instead of manually entering the IP address.
LinkRunner information
Displays LinkRunner Duo’s serial number, MAC address, and software version
numbers.
Fiber SFP information
Displays status of the SFP fiber adapter, the SFP adapter type, vendor information,
revision code information, and the SFP fiber adapter serial number. Some information
may not be provided by the SFP adapter vendor and will be left blank.
