Static Multicast Filters (5300xl Only)
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 9-19). 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 Advanced Traffic Management Guide for your
switch.)
On the 5300xl switches, 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.

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 Advanced Traffic Management 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
