Chapter 8 Configuring VLANs

Configuring VLANs

Configuring a VLAN

Note When you configure VLANs on access points, the Native VLAN must be VLAN1. In a single architecture, client traffic received by the access point is tunneled through an IP-GRE tunnel, which is established on the access point’s Ethernet interface native VLAN. Because of the IP-GRE tunnel, some users may confgure another switch port as VLAN1. This misconfiguration causes errors on the switch port.

Configuring your access point to support VLANs is a three-step process:

1.Enable the VLAN on the radio and Ethernet ports.

2.Assign SSIDs to VLANs.

3.Assign authentication settings to SSIDs.

This section describes how to assign SSIDs to VLANs and how to enable a VLAN on the access point radio and Ethernet ports. For detailed instructions on assigning authentication types to SSIDs, see Chapter 6, “Configuring Authentication Types.” For instructions on assigning other settings to SSIDs, see Chapter 3, “Configuring Multiple SSIDs.”

You can configure up to 16 SSIDs on the access point, so you can support up to 16 VLANs that are configured on your LAN.

Beginning in privileged EXEC mode, follow these steps to assign an SSID to a VLAN and enable the VLAN on the access point radio and Ethernet ports:

	Command	Purpose
Step 1
	configure terminal	Enter global configuration mode.
Step 2
	interface dot11radio 0 1	Enter interface configuration mode for the radio interface.
Step 3
	ssid ssid-string	Create an SSID and enter SSID configuration mode for the new
		SSID. The SSID can consist of up to 32 alphanumeric
		characters. SSIDs are case sensitive.
		Note	You use the ssid command’s authentication options to
			configure an authentication type for each SSID. See
			Chapter 6, “Configuring Authentication Types,” for
			instructions on configuring authentication types.
Step 4
	vlan vlan-id	(Optional) Assign the SSID to a VLAN on your network. Client
		devices that associate using the SSID are grouped into this
		VLAN. Enter a VLAN ID from 1 to 4095. You can assign only
		one SSID to a VLAN.
		Tip	If your network uses VLAN names, you can also assign
			names to the VLANs on your access point. See the
			“Assigning Names to VLANs” section on page 8-7for
			instructions.
Step 5
	exit	Return to interface configuration mode for the radio interface.
Step 6
	interface dot11radio 0.x 1.x	Enter interface configuration mode for the radio VLAN sub
		interface.
