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
Interface Line Protocol Utilization[In Percent]
Te 0/5 Up 0
Te 0/7 Up 0
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.
Table 13. 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 over-utilization of the
port channel occurred. The value, Active, is displayed for this field.
Interface Slot and port number, and the type of the member interface of the
port channel
Line Protocol Indicates whether the interface is administratively up or down
Utilization (In Percent) Traffic usage in percentage of the packets processed by the
particular member interface
