This document describes how to configure and manage MAC address, IP, and Ethertype filters on the
Cisco wireless mobile interface card (WMIC). It contains these sections:

Understanding Filters
Protocol filters (IP protocol, IP port, and Ethertype) prevent or allow the use of specific protocols
through the WMIC 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 WMIC's radio port prevents SNMP access through the radio 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 filter by entering commands in the command-line interface (CLI).
Tip
You can include filters in the WMIC's QoS policies. Refer to
detailed instructions on setting up QoS policies.
