Figure 11-13. Named Source-Port Filters Managing TrafficStatic Multicast Filters

This filter type enables the switch to forward or drop multicast traffic to a specific set of destination ports. This helps to preserve bandwidth by reducing multicast traffic on ports where it is unnecessary, and to isolate multicast traffic to enhance security.

You can configure up to 16 static multicast filters (defined by the filter command—page 11-21). However, if an IGMP-controlled filter for a joined multicast group has the same multicast address as a static multicast filter configured on a given port, the IGMP-controlled filter overrides the static multicast filter configured on that port. Note that in the default configuration, IGMP is disabled on VLANs configured in the switch. To enable IGMP on a specific VLAN, use the vlan < vid > ip igmp command. (For more on this command, refer to the chapter titled “Multimedia Traffic Control with IP Multicast (IGMP)” in the Multicast and Routing Guide for your switch.)

The total of static multicast filters and IGMP multicast filters together can range from 389 to 420, depending on the current max-vlanssetting in the switch. If multiple VLANs are configured, then each filter is counted once per VLAN in which it is used.
