Enabling the Verification of Member Links Utilization in a
LAG Bundle
To examine the working efficiency of the LAG bundle interfaces, do the following
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 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
Interface Line Protocol Utilization[In Percent]

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. Such a method of analyzing and tracking the number of
packets processed by the member interfaces in percentage enables you to optimally and effectively
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
mechanism is supported on I/O Aggregators in stacking, standalone, and VLT modes and it is not
supported in programmable MUX (PMUX) mode. 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 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.
Table 3. Output Field Descriptions for show link-bundle-distribution port-channel Command
Field Description
Link-bundle trigger threshold Threshold value that is the checkpoint, exceeding
which the link bundle is marked as being
overutilized and alarm is generated
LAG bundle number Number of the LAG bundle
Utilization (In Percent) Traffic usage in percentage of the packets
processed by the port channel
Alarm State Indicates whether an alarm is generated if
overutilization of the port channel occurred. The
value, Active, is displayed for this field.
