Chapter 31 Configuring Network Security with ACLs

Applying a VLAN Map to a VLAN

Beginning in privileged EXEC mode, follow these steps to apply a VLAN map to one or more VLANs:
Command
Step 1
configure terminal
Step 2 vlan filter mapname vlan-list list
Step 3 show running-config
Step 4
copy running-config startup-config
To remove the VLAN map, use the no vlan filter mapname vlan-list list global configuration command.
This example shows how to apply VLAN map 1 to VLANs 20 through 22:
Switch(config)# vlan filter map 1 vlan-list 20-22

Wiring Closet Configuration

In a wiring closet configuration, the switch can support a VLAN map and a QoS classification ACL.In
a wiring closet configuration, routing might not be enabled on the switch. In this configuration, the
switch can still support a VLAN map and a QoS classification ACL. In
and Host Y are in different VLANs and are connected to wiring closet switches A and C. Traffic from
Host X to Host Y is eventually being routed by Switch B, a Layer 3 switch with routing enabled. Traffic
from Host X to Host Y can be access-controlled at the traffic entry point, Switch A.

Purpose
Enter global configuration mode.
Apply the VLAN map to one or more VLAN IDs.
The list can be a single VLAN ID (22), a consecutive list (10-22), or a string
of VLAN IDs (12, 22, 30). Spaces around the comma and hyphen are
optional.
Display the access list configuration.
(Optional) Save your entries in the configuration file.
