Multimedia Traffic Control with IP Multicast (IGMP) IGMP General Operation and Features Notes Whenever IGMP is enabled, the switch generates an Event Log message indicating whether querier functionality is enabled. IP multicast traffic groups are identified by IP addresses in the range of 224.0.0.0 to 239.255.255.255. Also, incoming IGMP packets intended for reserved, or "well-known" multicast addresses automatically flood through all ports (except the port on which the packets entered the switch). For more on this topic, see "Excluding Well-Known or Reserved Multicast Addresses from IP Multicast Filtering" on page 2-19. For more information, refer to "How IGMP Operates" on page 2-12. Number of IP Multicast Addresses Allowed The total of IGMP filters (addresses) and static multicast filters together is 2,047 (if data driven) or 2,048 otherwise, depending on the current max-vlans configuration. If multiple VLANs are configured, then each filter is counted once per VLAN in which it is used. 2-6

Multimedia Traffic Control with IP Multicast (IGMP)
IGMP General Operation and Features
Notes
Whenever IGMP is enabled, the switch generates an Event Log message
indicating whether querier functionality is enabled.
IP multicast traffic groups are identified by IP addresses in the range of
224.0.0.0 to 239.255.255.255. Also, incoming IGMP packets intended for
reserved, or “well-known” multicast addresses automatically flood through all
ports (except the port on which the packets entered the switch). For more on
this topic, see “Excluding Well-Known or Reserved Multicast Addresses from
IP Multicast Filtering” on page 2-19.
For more information, refer to “How IGMP Operates” on page 2-12.
Number of IP Multicast Addresses Allowed
The total of IGMP filters (addresses) and static multicast filters together is
2,047 (if data driven) or 2,048 otherwise, depending on the current
max-vlans
configuration. If multiple VLANs are configured, then each filter is counted
once per VLAN in which it is used.
