If you disable VLAN1 it's disabled just for user data. But there is still some traffic remaining - there are some Cisco proprietary protocols which always use VLAN1 (BPDUs for "common Spanning Tree", VTP, CMP, etc.). You are not able to completly diasable VLAN1, I'm afraid.
I don't know one material containing this info in clear form; it's mentioned just "between lines" in different manuals (try to look at Cat 4000 configuration manual, STP section, e.g.).
It does depend what your native vlan on your trunk links. If you move the management vlan from vlan 1 to another vlan then you should be able to prune vlan 1 (at least from 6500,4000 switches) You can't with the 3500 series switches, they always keep vlan 1 on the allowed vlans on a trunk.
This feature is not supported on all platforms and software. Actually, disabling of VLAN 1 only prevents Data Traffic on VLAN 1 from crossing a trunk, management traffic still passes. It is a useful feature as it limits the diameter of VLAN1.
Move your SC0 interface to another VLAN other than VLAN 1. Your objective should be to move all "user-data" off VLAN 1. There is no harm to leave VLAN 1 enabled - just don't use it. The switches need VLAN 1 for the VLAN 1 tagged management traffic that is generated. This is very important "switch-data".
Even if you disable or prune VLAN 1, VLAN 1 tagged "switch-data" will still traverse the switches using CMP (Cisco Management Protocol).
We have 3 identical switches configured by someone else and would like to claim some of the Gigabit ports(G1/G2/G3/G4) for use on servers. When we try to change the wiring and configuration, we run in to connectivity issues. Attached is a des...
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
