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 WMIC 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 WMIC’s
Ethernet port.
In fundamental terms, the key to configuring a WMIC 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 WMIC is configured to recognize a specific VLAN ID, a connection to the VLAN is established.
The WMIC supports 16 SSIDs. You can assign only one SSID to the native VLAN.
Configuring VLANs
These sections describe how to configure VLANs on your WMIC:
• Configuring a VLAN, page 10-4
• Viewing VLANs Configured on the WMIC, page 10-7
Configuring a VLAN
Configuring your WMIC to support VLANs is a five-step process:
1. Create subinterfaces on the radio and Ethernet interfaces.
2. Enable 802.1q encapsulation on the subinterfaces and assign one subinterface as the native VLAN.
3. Assign a bridge group to each VLAN.
4. (Optional) Enable WEP on the native VLAN.
5. Assign the WMIC’s SSID to the native VLAN.
This section describes how to assign an SSID to a VLAN and how to enable a VLAN on the WMIC radio
and Ethernet ports. For detailed instructions on assigning authentication types to SSIDs, see Chapter 8,
“Configuring Authentication Types.”
Beginning in privileged EXEC mode, follow these steps to assign an SSID to a VLAN and enable the
VLAN on the WMIC radio and Ethernet ports:
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
interface dot11radio0.x Create a radio subinterface and enter interface configuration
mode for the subinterface.
Step 3
encapsulation dot1q vlan-id
[native]
Enable a VLAN on the subinterface.
(Optional) Designate the VLAN as the native VLAN. On many
networks, the native VLAN is VLAN 1.
