Re: Cisco VLAN 1

Hi Janet

Cisco recommend using a separate vlan for managing your switches ie. don't use vlan 1 on the switch for remote access, and they also recommend putting all unused ports into a dummy vlan with no layer 3 interface - we use vlan 998 here where i work.

Note the vlan 1 will still be used by PagP, CDP, STP to send information down trunk links.

Attached is a paper on vlan security with a specific part on use of vlan 1.
