IGMP Snooping Configuration Rules

The IGMP snooping feature operates according to specific configuration rules.
When configuring your switch for IGMP snooping, consider the following rules
that determine how the configuration reacts in any network topology:
Note: Because IGMP snooping is set up per VLAN, all IGMP changes are
implemented according to the VLAN configuration for the specified ports.
For more information about using the IGMP snooping feature, see "IGMP
Configuration Menu" on page 3-78.
See also Appendix E, "Quick Steps to Features," for configuration flowcharts that
can help you use this feature.
309978-D Rev 01
A port that is currently configured for EAPOL-based security cannot be
configured as a static router port.
A port that is currently configured for port mirroring cannot be configured as
a static router port.
If a MultiLink Trunk member is configured as a static router port, all of the
MultiLink Trunk members are configured as static router ports. Also, if a
static router port is removed, and it is a MultiLink Trunk member, all
MultiLink Trunk members are automatically removed as static router port
members.
Static router ports must be port members of at least one VLAN.
If a port is configured as a static router port, it is configured as a static router
port for all VLANs on that port. The IGMP configuration is propagated
through all VLANs of that port.
If a static router port is removed, the membership for that port is removed
from all VLANs of that port.
The IGMP snooping feature is not STP dependent.
The IGMP snooping feature is not Rate Limiting dependent.
The snooping field must be enabled for the proxy field to have any valid
meaning.
Static router ports are configured per VLAN and per IGMP Version.
