Removing a vlan from vlan group in FWSM

nkariyawasam — Mon, 11 Mar 2019 13:27:22 GMT

I have following vlan groups assigned to FWSM in 6500 and it is production;

firewall vlan-group 1 100,200,400,800

Now I want to remove just VLAN 800 from the group. If I enter the command;

no firewall vlan-group 1 800

will it affect the traffic in other vlan s? I want to know this from someone whoi has done it practically, becase the traffic in other segnemnts are really critical, and I want zero disturbance for them.

Do you mean will "no firewall vlan-group 1 800" remove the other vlans from the vlan-group 1? Then the answer is NO!, your show run will become:

firewall vlan-group 1 100,200,400

If you mean affect in the literal sense, then only you can tell that. Pretty difficult to tell you that by seeing only one line in your ocnfig 🙂
