Field Description
Uptime Displays the age of the port channel in hours:minutes:seconds.
Ports Lists the interfaces assigned to this port channel.
(untitled) Displays the status of the physical interfaces (up or down).
● In Layer 2 port channels, an * (asterisk) indicates which interface is the primary
port of the port channel. The primary port sends out interface PDU.
● In Layer 3 port channels, the primary port is not indicated.
Example
Dell#show int po bri
Codes: L - LACP Port-channel
O - OpenFlow Controller Port-channel
A - Auto Port-channel
I - Internally Lagged
LAG Mode Status Uptime Ports
L 128 L3 down 00:00:00
Dell#
To indicate the LACP fallback, Internally lagged is added to the list. When the LAG auto-
configures itself, the LAG status describes as ‘I’.

Time Domain Reflectometer (TDR) Commands
TDR is useful for troubleshooting an interface that is not establishing a link; either it is flapping or not coming up at all. TDR
detects open or short conditions of copper cables on 100/1000/10G Base-T modules.
● tdr-cable-test
● show tdr
Important Points to Remember
● The interface and port must be enabled (configured—see the interface command) before running TDR. An error
message is generated if you have not enabled the interface.
● The interface on the far-end device must be shut down before running TDR.
● Because TDR is an intrusive test on an interface that is not establishing a link, do not run TDR on an interface that is passing
traffic.
● When testing between two devices, do not run the test on both ends of the cable.
