5324 disable vlan 1

Hi,

I would like disable vlan 1. I read in cli manual about  command default-vlan disable. But in my 5324 is not that option.

I updated to the newest firmware but still do not have that command. Does this device recognize this command?

sw3g.sh(config-vlan)#
  do                   execute an EXEC-level command
  end                  Exit from configure mode
  exit                 Exit from current context
  map                  Map protocol to group ID
  no                   Negate command
  vlan                 Create a new VLAN
sw3g.sh(config-vlan)# do show ver

Boot version    1.0.2.02 ( date  23-Jul-2006 time  16:45:47 )
HW version    00.00.02
sw3g.sh(config-vlan)#


Thank you in advance
