Is there any way to add vlan to existing vlan-id, just how we do at 7mode...

curretly we are using 9.4p1 cmode....

below vlan already exists....so now if i want to create a0b for the same vlan id 608, am not getting vlan add here, so..

if i use ,network port vlan create -node  cluster-01   -vlan-name a0b-608... is there any outage to this id 608, which is already running in production...?
