Traffic/Security Filters and Monitors

Filter Types and Operation

Table 12-2. Multicast Filter Limits

Notes Per-Port IP Multicast Filters. The static multicast filters described in this

section filter traffic having a multicast address you specify. To filter all

multicast traffic on a per-VLAN basis, refer to the section titled “Configuring

and Displaying IGMP” in the chapter titled “Multimedia Traffic Control with

IP Multicast (IGMP)” in the Multicast and Routing Guide for your switch.

IP Multicast Filters. Multicast filters are configured using the Ethernet

format for the multicast address. IP multicast addresses occur in the range of

224.0.0.0 through 239.255.255.255 (which corresponds to the Ethernet multi-

cast address range of 01005e-000000 through 01005e-7fffff). Any static Traffic/

Security filters configured with a multicast filter type and a multicast address

in this range will continue to be in effect unless IGMP learns of a multicast

group destination in this range. In this case, IGMP takes over the filtering

function for the multicast destination address(es) for as long as the IGMP

group is active. If the IGMP group subsequently deactivates, the static filter

resumes control over traffic to the multicast address.

Caution If Spanning Tree is enabled, then the MSTP multicast MAC address (0180c2-

000000) should not be filtered. (STP will not operate properly if the MSTP

multicast MAC address is filtered.)

Protocol Filters

This filter type enables the switch to forward or drop, on the basis of protocol

type, traffic to a specific set of destination ports on the switch. Filtered

protocol types include:
