Re: Back-up local controller

Hi Joseph,

 

Let me try if I can make it specific. In the "show vlan status", I am seeing the Operstate is "down" for all vlans in a local backup controller B while vlans are "up" for same vlans in the master controller A. To my knowledge, vrrp is running on these two controllers and GRE tunnels are from other controllers to one or both. I just wonder if vlans are staying down till it's failed over. Thanks,

A vlan marked down unless (1) it is assigned to an interface that is up or (2) there is a user in that VLAN.  To make it always up in that situation, do this:

 

config t

interface vlan x

operstate up
