Configuring Wireless LANs
Activating Wireless LANs
After you have completely configured your wireless LAN settings, enter
config wlan enable
wlan-id
to
activate the wireless LAN.
Assigning a Wireless LAN to a DHCP Server
Each wireless LAN can be assigned to a DHCP server. Any or all wireless LANs can be assigned to the
same DHCP server, and each wireless LAN can be assigned to different DHCP servers.
Note
DHCP servers must be assigned for wireless LANs that allow management through a wireless
connection.
•
Enter this command to assign a wireless LAN to a DHCP server:
config wlan dhcp_server
wlan-id
dhcp-server-ip-address
•
Enter
show wlan
to verify that the wireless LAN is assigned to the DHCP server.
Configuring MAC Filtering for Wireless LANs
When you use MAC filtering for client or administrator authorization, you need to enable it at the
wireless LAN level first. If you plan to use local MAC address filtering for any wireless LAN, use the
commands in this section to configure MAC filtering for a wireless LAN.
Enabling MAC Filtering
Use these commands to enable MAC filtering on a wireless LAN:
•
Enter
config wlan mac-filtering enable
wlan-id
to enable MAC filtering.
•
Enter
show wlan
to verify that you have MAC filtering enabled for the wireless LAN.
When you enable MAC filtering, only the MAC addresses that you add to the wireless LAN are allowed
to join the wireless LAN. MAC addresses that have not been added are not allowed to join the wireless
LAN.
Creating a Local MAC Filter
Cisco Wireless LAN Controllers have built-in MAC filtering capability, similar to that provided by a
RADIUS authorization server.
Use these commands to add MAC addresses to a wireless LAN MAC filter:
•
Enter
show macfilter
to view MAC addresses assigned to wireless LANs.
•
Enter
config macfilter add
mac-addr
wlan-id
to assign a MAC address to a wireless LAN MAC
filter.
•
Enter
show macfilter
to verify that MAC addresses are assigned to the wireless LAN.
