Configuring WLANs
Step 11 To see the list of configured DHCP scopes, enter this command:
show dhcp summary
Information similar to the following appears:
Scope Name Enabled Address Range
Scope 1 No 0.0.0.0 -> 0.0.0.0

Configuring MAC Filtering for WLANs
When you use MAC filtering for client or administrator 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 commands in this
section to configure MAC filtering for a WLAN.
Enabling MAC Filtering
Use these commands to enable MAC filtering on a WLAN:
• 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 WLAN.
When you enable MAC filtering, only the MAC addresses that you add to the WLAN are allowed to join
the WLAN. MAC addresses that have not been added are not allowed to join the WLAN.
Creating a Local MAC Filter
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 WLAN MAC filter:
• Enter config macfilter add mac_addr wlan_id [interface_name] [description] [IP_addr] to create
a MAC filter entry on the controller, where the following parameters are optional:
–
interface_name—The name of the interface.
–
description—A brief description of the interface in double quotes.
–
IP_addr—The IP address of the local MAC filter database.
