Monitoring the Member Links of a LAG Bundle
You can examine and view the operating eciency and the trac-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 eciency of the LAG bundle interfaces is
automatically activated on all the port channels, except the port channel that is congured 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 trac-
handling and utilization of the member interfaces of the port channel. The following table describes the output elds 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) Trac 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 eld.
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) Trac 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
link-bundle-monitor enable
Verifying LACP Operation and LAG Conguration
To verify the operational status and conguration of a dynamically created LAG, and LACP operation on a LAG on an Aggregator, enter the
show interfaces port-channel port-channel-number and show lacp port-channel-number commands.
The show outputs in this section for uplink LAG 128 and server-facing LAG 1 refer to the LACP Operation on an Aggregator gure
show interfaces port-channel 128
Command Example
Dell# show interfaces port-channel 128
Port-channel 128 is up, line protocol is up
