Can a port share then be added to an MLAG? Client wants to have Layer 2 or Layer 3 sharing capabilities and then do a MLAG using those ports or the sharing ports. Is there some way to do this? Currently they have a Stack and are sharing between the Stack. They want to break the stack so as to be able to perform a firmware upgrade without taking everything down. In order to do this they want the sharing for the ports that are going to their virtual environment as well as be able then to MLAG them together between the switches.
