Chapter 13 Configuring VLANs
Configuring VLANs
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 10, “Configuring Authentication Types.” For instructions on assigning other settings to SSIDs,
see Chapter 7, “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:
This example shows how to:
• Name an SSID
• Assign the SSID to a VLAN
• Enable the VLAN on the radio and Ethernet ports as the native VLAN
ap1200# configure terminal
ap1200(config)# interface dot11radio0
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
interface dot11radio0 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 10, “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.
Step 5
exit Return to interface configuration mode for the radio interface.
Step 6
interface dot11radio0.x Enter interface configuration mode for the radio VLAN sub
interface.
Step 7
encapsulation dot1q vlan-id
[native]
Enable a VLAN on the radio interface.
(Optional) Designate the VLAN as the native VLAN. On many
networks, the native VLAN is VLAN 1.
Step 8
exit Return to global configuration mode.
Step 9
interface fastEthernet0.x Enter interface configuration mode for the Ethernet VLAN
subinterface.
Step 10
encapsulation dot1q vlan-id
[native]
Enable a VLAN on the Ethernet interface.
(Optional) Designate the VLAN as the native VLAN. On many
networks, the native VLAN is VLAN 1.
Step 11
end Return to privileged EXEC mode.
Step 12
copy running-config startup-config (Optional) Save your entries in the configuration file.
