Filter Setup
Enabling a Protocol Filter
Follow these steps to enable a protocol filter:
Step 1 Complete the steps listed in the “Creating a Protocol Filter” section on page 3-9
to define a protocol filter.
Step 2 Follow the link path to the Ethernet Protocol Filters page or the AP Radio Protocol
Filters page.
Step 3 Select the protocol filter set that you want to enable from the Ethertype, IP
Protocol, or IP Port pull-down menu.
Step 4 Click OK. The filter set is enabled.
MAC Address Filtering
MAC address filters allow or disallow the forwarding of unicast and multicast
packets either sent from or addressed to specific MAC addresses. You can create
a filter that passes traffic to all MAC addresses except those you specify, or you
can create a filter that blocks traffic to all MAC addresses except those you
specify.
Note MAC address filters are powerful, and you can lock yourself out of the access
point if you make a mistake setting up the filters. If you accidentally lock yourself
out of your access point, follow the instructions in the “Using the Command-Line
Interface” section on page 2-5 to use the CLI to disable the filters.
Use the Address Filters page to create MAC address filters for the access point.
Figure 3-8 shows the Address Filters page.
