• If you are modifying enabled WLANs, be sure they are disabled using the show wlan summary
command. If they are not disabled, use the following to disable them:
>config wlan disable <wlan id>
where <wlan id> = 1 through 16. Leave the WLANs in disabled mode until you have finished
configuring them.
• If you are deleting WLANs, use the following command:
>config wlan delete <wlan id>
where <wlan id> = 1 through 16.
DHCP ServerDHCP Server
Each WLAN can be assigned to a DHCP server. Any or all WLANs can be assigned to the same DHCP
server, and each WLAN can be assigned to a different DHCP servers. This assignment is mandatory for
WLANs that allow Management over Wireless, as described in External DHCP Servers.
• Use the show wlan command to verify whether you have a DHCP Server assigned to the WLAN.
• If necessary, use the following command:
>config wlan dhcp_server <WLAN id> <IP Address>
where <WLAN id> = 1 through 16, <IP Address> = DHCP Server IP Address.
• Use the show wlan command to verify that you have a DHCP Server assigned to the WLAN.
MAC FilteringMAC Filtering
Whenever you are going to use MAC filtering for Cisco Wireless LAN Controller or RADIUS authorization,
you need to enable it at the WLAN level first. If you plan to use local MAC address filtering for any
WLAN, use the following commands to configure the MAC Address Filter List:
• Use the show wlan command to verify whether you have MAC filtering enabled or disabled for
each WLAN.
• If necessary, use the following command:
>config wlan mac-filtering enable <WLAN id>
where <WLAN id> = 1 through 16.
• Use the show wlan command to verify that you have MAC filtering enabled or disabled for each
WLAN.
Local MAC FilterLocal MAC Filter
Cisco Wireless LAN Controllers have built-in MAC filtering capability, similar to that provided by a
RADIUS authorization server.
• Use the show macfilter command to verify that you have MAC addresses assigned to WLANs.
• If required, use the following commands to assign local MAC addresses to WLANs, and to
configure a WLAN to filter a local client:
>config macfilter add <MAC addr> <WLAN id>
>config macfilter wlan-id <MAC addr> <WLAN id>
where <MAC addr> = client MAC address and <WLAN id> = 1 through 16.
• Use the show macfilter command to verify that you have MAC addresses assigned to WLANs.
