MLAG on EXOS allows to configure an alternate IP address for the peer switch, see e.g. How to implement MLAG alternate peer ipaddress
. This disables the MLAG ports of one of the two MLAG peers in case of an ISC failure, thus preventing problems caused by the split-brain situation.
How is the switch determined that disables the MLAG ports? Can this be configured, e.g. by setting a priority? Is there a show
command available to find out which of the switches is supposed to disable MLAG ports in case of an ISC failure?
