Preserving LAG and Port Channel Settings in Nonvolatile
Storage
Use the write memory command on an I/O Aggregator, which operates in either standalone or PMUX
modes, to save the LAG port channel configuration parameters. This behavior enables the port channels
to be brought up because the configured interface attributes are available in the system database during
the booting of the device. With the reduction in time for the port channels to become active after the
switch is booted, the loss in the number of packets that are serviced by these interfaces is minimized.
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.

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.
