This chapter covers the following key topics:

  • VLAN Access Lists— This section discusses how traffic can be controlled within a VLAN. You can use VLAN access control lists (ACL) to filter packets even as they are bridged or switched.

  • Private VLANs— This section explains the mechanisms that you can use to provide isolation within a single VLAN. Private VLANs have a unidirectional nature; several of them can be isolated yet share a common subnet and gateway.

  • Securing VLAN Trunks— This section covers two types of attacks that can be leveraged against a VLAN trunk link. If a trunk link is extended to or accessible from an attacker, any VLAN carried over the trunk can be compromised in turn.
