The ezMLAG2 wizard, which is new for ExtremeXOS 21.1, was created to simplify the configuration of MLAG peers and devices. It also helps prevent users from configuring MLAGs that should not be done between peer switches.
Note
The multi-switch link aggregation group (MLAG) feature allows you to combine ports on two switches to form a single logical connection to another network device. MLAG requires two ExtremeXOS switches interconnected by an Inter-Switch Connection (ISC). These connected peers can then monitor the health of the ISC using a keep-alive protocol that periodically sends health-check messages. If the ISC link alone goes down when the remote peer is alive, both the MLAG peers forward the south-bound traffic, resulting in duplication of traffic. However, this does not create a traffic loops. For more information about MLAG, see "Configuring Slots and Ports on a Switch" in the ExtremeXOS User Guide.
