Configuring VLANs

Incorporating Wireless Bridges into VLANs

The basic wireless components of a VLAN consist of two or more bridges communicating using wireless
technology. The bridge is physically connected through a trunk port to the network VLAN switch on
which the VLAN is configured. The physical connection to the VLAN switch is through the bridge's
Ethernet port.
In fundamental terms, the key to configuring a bridge to connect to a specific VLAN is by configuring
its SSID to recognize that VLAN. Since VLANs are identified by a VLAN ID, it follows that if the SSID
on a bridge is configured to recognize a specific VLAN ID, a connection to the VLAN is established.
The bridge supports only one SSID. You should assign the SSID to the native VLAN.

Configuring a VLAN

Configuring your bridge to support VLANs is a five-step process:
1.
2.
3.
4.
5.
This section describes how to assign an SSID to a VLAN and how to enable a VLAN on the bridge radio
and Ethernet ports. For detailed instructions on assigning authentication types to SSIDs, see
"Configuring Authentication Types."
Beginning in privileged EXEC mode, follow these steps to assign an SSID to a VLAN and enable the
VLAN on the bridge radio and Ethernet ports:

Step 1 configure terminal
Step 2 interface dot11radio0.x
Step 3 encapsulation dot1q vlan-id

Create subinterfaces on the radio and Ethernet interfaces.
Enable 802.1q encapsulation on the subinterfaces and assign one subinterface as the native VLAN.
Assign a bridge group to each VLAN.
(Optional) Enable WEP on the native VLAN.
Assign the bridge's SSID to the native VLAN.
Purpose
Enter global configuration mode.
Create a radio subinterface and enter interface configuration
mode for the subinterface.
Enable a VLAN on the subinterface.
(Optional) Designate the VLAN as the native VLAN. On many
networks, the native VLAN is VLAN 1.
