Number Of Ip Multicast Addresses Allowed - SMC Networks SMC6624M Management Manual

Configuring Advanced Features
Multimedia Traffic Control with IP Multicast (IGMP)
group is active. If the IGMP group subsequently deactivates, the static filter
resumes control over traffic to the multicast address formerly controlled by
IGMP. (Note that the SMC6624M does not have traffic/security filters.)
Well-Known or Reserved Multicast Addresses Excluded from IP
Multicast (IGMP) Filtering . Each multicast host group is identified by a
single IP address in the range of 224.0.0.0 through 239.255.255.255. Specific
groups of consecutive addresses in this range are termed "well-known"
addresses and are reserved for predefined host groups. IGMP does not filter
these addresses, so any packets the switch receives for such addresses are
flooded out all ports assigned to the VLAN on which they were received
(except the port on which the packets entered the VLAN). The following table
lists the 32 well-known address groups (8192 total addresses) that IGMP does
not filter on the SMC6624M switch.

Number of IP Multicast Addresses Allowed

Multicast filters and IGMP filters (addresses) together can total up to 255 in
the switch. If multiple VLANs are configured, then each filter is counted once
per VLAN in which it is used.
