IGMP Snooping Version
The membership reports sent to the multicast router are sent based on the IGMP
snooping version of the interface. If you statically specify the version on a certain
interface, the reports are always sent out only with the specified version. If you do not
statically specify the version, and a version 1 query is received on the interface, the
interface dynamically sends out a version 1 report. If no version 1 query is received on
the interface for the version 1 router present timeout period (400 seconds), the interface
version goes back to its default value (3).
To specify the static IGMP snooping version, use the following command.
