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 1. 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

You can also use the show running-configuration interface port-channel command in EXEC Privilege mode to view whether the mechanism to evaluate the utilization of the member interfaces of the LAG bundle is enabled. The following sample output illustrates the portion of this show command:

Dell#show running-config int port-channel 1
                                 !
                                 interface Port-channel 1
                                 mtu 12000
                                 portmode hybrid
                                 switchport
                                 vlt-peer-lag port-channel 1
                                 no shutdown
