Filter Setup
Select Disallowed or Allowed from the pull-down menu for Default Multicast
Address Filter. The access point discards all multicast traffic except packets sent
to the MAC addresses listed as allowed on the Address Filters page.
Step 8 Click OK. You return automatically to the Setup page.
If clients are not filtered immediately, click WARM RESTART SYSTEM NOW
on the Manage System Configuration page to restart the access point. To reach the
Manage System Configuration page, Click Cisco Services on the main Setup page
and click Manage System Configuration on the Cisco Services Setup page.
Note The Ethernet Advanced page contains the Default Unicast and Multicast Address
Filter settings for the Ethernet port. These settings work as described above,
except that they affect traffic sent from the radio to the Ethernet. However, you
should use extra caution changing the settings on the Ethernet Advanced page
because they can lock you out of your access point. To reach the Ethernet
Advanced page, click Advanced in the Ethernet row of the Network Ports section
at the bottom of the Setup page.
Note Client devices with blocked MAC addresses cannot send or receive data through
the access point, but they might remain in the Association Table as
unauthenticated client devices. Client devices with blocked MAC addresses
disappear from the Association Table when the access point stops monitoring
them or they associate with another access point. See the “Association Table
Advanced Page” section on page 3-62 for information on setting a monitoring
timeout for each device class.
