Hello, We have two Dell N4000 series switches that are connected with a 10GB link for the MLAG Peer Network. When we turn on MLAG I lose connectivity to the one switch. I turn off MLAG and it comes back without any issues. I am trying to figure out why the switch drops offline when I turn on MLAG. Any help would be greatly appreciated. Thanks for your assistance.
