Dell PowerEdge FN I/O Module Configuration Guide 9.10(0.0)

You can enable or disable auto LAG on the server-facing interfaces. By default, auto LAG is enabled. This functionality is supported on the Aggregator in Standalone, Stacking, and VLT modes.

1. Enable the auto LAG on all the server ports. CONFIGURATION mode io-aggregator auto-lag enable Dell(config)# io-aggregator auto-lag enable

   To disable the auto LAG on all the server ports, use the no io-aggregator auto-lag enable command. When disabled, all the server ports associated in a LAG are removed and the LAG itself gets removed. Any LACPDUs received on the server ports are discarded.

   In VLT mode, the global auto LAG is automatically synced to the peer VLT through ICL message.

2. Enable the auto LAG on a specific server port. Interface Configuration mode auto-lag enable Dell(conf-if-te-0/1)# auto-lag enable

   To disable the auto LAG, use the no auto-lag enable command. When disabled, the server port is removed from the LAG and if the server port is the last member of the LAG, the LAG itself gets removed. Any LACPDUs received on the server port are discarded.

   In VLT mode, the interface level auto LAG configuration is not synced to the peer. Only the global auto LAG is synced to the peer.

3. View the auto LAG configurations. EXEC mode show io-aggregator auto-lag status

   Dell# show io-aggregator auto-lag status
                                       
                                       Auto LAG creation on server port(s) is enabled
                                    

   For the interface level auto LAG configurations, use the show interface command.

   Dell(conf-if-te-0/1)#no auto-lag enable
