This presentation has a lot of L2 security considerations, including VLAN1.

With the current configuration 1. All trunks have a native VLAN, which is not used by any User. 2. Management VLAN is other than VLAN 1. We have different VLANs in place, however these are only used for different Servers ,And all Users are only members of VLAN-1 Does it make sense to have all the user ports migrated to a Different VLAN (other than VLAN 1) ? Is there a security advantage in this ? Regards \\ Naman
