[nsp] Can I disable VLAN1 on a 2900XL?

[Dowd, Everett]

Yes, it is pretty easy and all you need to do is have the most recent code
(I think 12.0.WC5 will work) and an 8M switch to change the native VLAN. 

All you need to do is create a new vlan and then when you trunk to a router,
just assign the sub-interface to the new native VLAN.

Here is my example...

interface Vlan1
 no ip address
 no ip route-cache
 shutdown
!
interface Vlan2
 ip address 10.1.1.2 255.255.255.0
 no ip redirects
 no ip route-cache
!

Router config
interface FastEthernet0.2
 description main link for management and subnets
 encapsulation dot1Q 2 native
 ip address 10.1.1.1 255.255.255.0

No.  VLAN1 (well actually the default VLAN ont he trunk interfaces 
usually....) carries the spanning tree traffic and other important 
makes-your-network-work stuff.
