[c-nsp] Blocking vlan 1 on trunked ports?

[Geoffrey Cauchi]

On a 3550 switch, running the enhanced image,
c3550-i9q3l2-mz.121-22.EA1a, you can do VLAN 1 minimization.
Example:

interface FastEthernet0/24
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan 200
 switchport mode trunk

Hope this helps.

Geoff

The original poster is running a 3524XL with 12.0(5), if I
recall.
