Probably a stupid question, but how can you remove vlans from an existing firewall vlan-group on a 6500? I had a couple of test contexts set up on fwsm, and have now deleted them. I want to release the vlans back into the wild (without a blip to the production contexts), but I don't see any syntax to do this. Help! (and thanks in advance).

Hi,
If you have something like:
firewall vlan-group 9 10,20,22,30,32
firewall module 9 vlan-group 9 -----> slot installed with FWSM
and would like to remove@release one (e.g vlan 20) or more vlan from the firewall group, use:
no firewall vlan-group 9 10,20,22,30,32
firewall vlan-group 9 10,22,30,32

CatOS:
If you have vlan 10,20,22,30 & 32 in fwsm's firewall-vlan 9 (9 is a tag to easily identify which slot fwsm sits)
To remove, use 'clear' command. To add, use 'set' command, .e.g to remove vlan 20 from fwsm vlan-group:
switch(enable) clear vlan 10,22,30,32 firewall-vlan 9
switch(enable) set vlan 10, 22,30,32 firewall-vlan 9

Well, I said initially that it might be a stupid question, and it was ...
I couldn't really use
no firewall vlan-group 9 10,20,22,30,32
firewall vlan-group 9 10,22,30,32
because I was concerned about a (however momentary) "blip" in service to the contexts using the remaining vlans. In retrospect, it should have been obvious to try
no firewall vlan-group 9 20
which works.
