Enabling the Verification of Member
Links Utilization in a LAG Bundle
To examine the working efficiency of the LAG bundle interfaces, perform the following steps:
1 The functionality to detect the working efficiency of the LAG bundle interfaces is automatically activated
on all the port channels, except the port channel that is configured as a VLT interconnect link, during
the booting of the switch.
2 Use the show link-bundle-distribution port-channel interface-number command to
display the traffic handling and utilization of the member interfaces of the port channel. The following
sample output is displayed when you enter this show command.
EXEC
Dell#show link-bundle-distribution port-channel
Dell#show link-bundle-distribution port-channel 1
Link-bundle trigger threshold - 60
LAG bundle - 1 Utilization[In Percent] - 0 Alarm State - Inactive

Monitoring the Member Links of a LAG
Bundle
You can examine and view the operating efficiency and the traffic-handling capacity of member interfaces of
a LAG or port channel bundle. This method of analyzing and tracking the number of packets processed by the
member interfaces helps you manage and distribute the packets that are handled by the LAG bundle. The
functionality to detect the working efficiency of the LAG bundle interfaces is automatically activated on all the
port channels, except the port channel that is configured as a VLT interconnect link, during the booting of the
switch. This functionality is supported on I/O Aggregators in PMUX, Standalone, and VLT modes. By default,
this capability is enabled on all of the port channels set up on the switch.
You can use the show link-bundle-distribution port-channel interface-number command to
display the traffic-handling and utilization of the member interfaces of the port channel. The following table
describes the output fields of this show command.
