Figure 11-13. Named Source-Port Filters Managing Traffic

Static 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-vlans setting in the

switch. If multiple VLANs are configured, then each filter is counted once per

VLAN in which it is used.
