CHAPTER 54
VLAN Access Control Lists
VLAN access control lists (ACLs) or VLAN maps access-control all packets (bridged and routed). You can
use VLAN maps to filter traffic between devices in the same VLAN. VLAN maps are configured to provide
access control based on Layer 3 addresses for IPv4. Unsupported protocols are access-controlled through
MAC addresses using Ethernet access control entries (ACEs). After a VLAN map is applied to a VLAN, all
packets (routed or bridged) entering the VLAN are checked against the VLAN map. Packets can either enter
the VLAN through a switch port or through a routed port after being routed.
This module provides more information about VLAN ACLs and how to configure them.
