Configuring Filters
This chapter describes how to configure and manage MAC address, IP, and
Ethertype filters on the access point by using the web browser interface.
Understanding Filters
Protocol filters (IP protocol, IP port, and Ethertype) prevent or allow the use of
specific protocols through the access point’s Ethernet and radio ports. You can set
up individual protocol filters or sets of filters. You can filter protocols for wireless
client devices, users on the wired LAN, or both. For example, an SNMP filter on
the access point’s radio port prevents wireless client devices from using SNMP
with the access point but does not block SNMP access from the wired LAN.
IP address and MAC address filters allow or disallow the forwarding of unicast
and multicast packets either sent from or addressed to specific IP or MAC
addresses. You can create a filter that passes traffic to all addresses except those
you specify, or you can create a filter that blocks traffic to all addresses except
those you specify.
You can configure filters by using the web browser interface or by entering
commands in CLI.

TIP
You can include filters in the access point’s QoS policies. See Configuring QoS on
page 457 for detailed instructions on setting up QoS policies.
By using CLI, you can configure up to 2,048 MAC addresses for filtering. By
using the web browser interface, however, you can configure only up to 43
MAC addresses for filtering.
