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.

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 configuration settings of the primary VLT node are synchronized with the secondary VLT peer node before the secondary VLT mode is up. The traffic outage is less than 200 millisconds during the restart or switchover of the VLT peer nodes from primary to secondary. 128 Link Aggregation
