802.1q & use VLAN 2 for admin

802.1Q uses VLAN1 and spanning tree depends on VLAN 1

But for security purpose, I need to use VLAN 2 instead of VLAN 1.

How can I do it ?

Re: 802.1q & use VLAN 2 for admin

Cisco Catalysts uses PVST Technology therefore STP does not depend from VLAN1.

The only difference (I don't mean frame structure ) from ISL VLAN1 that VLAN1 in

802.1q is untagged - native vlan.

Confige VLAN2 and use it.

Re: 802.1q & use VLAN 2 for admin

To change the native vlan on a trunked port on a catalyst, you simply change the vlan on the port. For example, to set the trunking on port 2/1 on a switch to trunk VLAN 100 using native vlan 2, you would enter...

set vlan 2

set trunk 2/1 on dot1q

set trunk 2/1 100

set vlan 2 2/1
