FWSM Basic question

Hello to everyone:-

i need guidence regarding FWSM. i am runing FWSM in my poroduction network and first time i am try to add and assigne one vlan to Fwsm.

i know the command which assigne vlan to FWSM that is below:

firewall vlan-group 1 vlan-id......

currently in my production  this command runing on FWSM.

firewall vlan-group 20  20,30-40,50

but i want to know if i want to add vlan 100 and assigne it to the FWSM whcih command is perfect.

1)Firewall vlan-group 20  20,30-40,50,100

2) Or just need firewall vlan-group 20  100. After executing this command vlan 100 will appended to old configration.

i am asking this question because i am little bit confuse may be command 2 will remove the previous vlan or append vlan 100 in the FWSM configration.

Thansk to the whole community.

FWSM Basic question

Hi,

Check out this document

http://www.cisco.com/en/US/docs/security/fwsm/fwsm32/command/reference/ef.html#wp1639443

Its the command reference for FWSM but lists some IOS commands too

It seems to suggest that you can only remove Vlans from the "firewall vlan-group" if you were to use the "no" parameter in front of the actual command.

I have personally usually only had the need to add or remove a single vlan and I have used the command as you describe.

As in "firewall vlan-group "
