Reference Guide

To configure the minimum number of member links that must be up for a LAG bundle to be fully up,
perform the following steps:
Specify the minimum number of member interfaces of the uplink LAG 128 bundle that must be up for
the LAG bundle to be brought up. The default minimum number of member links that must be active
for the uplink LAG to be active is 1. Enter the
minimum-links number command in the Port
Channel Interface 128 Configuration mode to specify this value.
Dell(conf)#interface port-channel 128
Dell(conf-if-po-128)#minimum-links 4
Use the show interfaces port-channel command to view information regarding the configured
LAG or port channel settings. The Minimum number of links to bring Port-channel up is field in the
output of this command displays the configured number of active links for the LAG to be enabled.

Optimizing Traffic Disruption Over LAG Interfaces On IOA
Switches in VLT Mode
When you use the write memory command while an Aggregator operates in VLT mode, the VLT LAG
configurations are saved in nonvolatile storage (NVS).
By restoring the settings saved in NVS, the VLT ports come up quicker on the primary VLT node and
traffic disruption is reduced. The delay in restoring the VLT LAG parameters is reduced (90 seconds by
default) on the secondary VLT peer node before it becomes operational. This makes sure that the
