Hi All,


We need to add  a new vlan and allow this to FWSM I have checked that there is no option for add in the firewall vlan-group command. I want to know if typed the command with existing vlan and the new vlan does it cause any isussues to the running environment.

No it won't cause any issues to the running environment but obviously if the vlan you add had any devices on it then they could be affected. You don't need to type out the full list again either. So if you had


firewall vlan-group 1 10,12,15


and you want to add vlan 30 then just type


firewall vlan-group 1 30


this will simply add vlan 30 to the existing list ie. it won't overwrite what is already there.
