47.1 Enabling IGMP Snooping

To enable IGMP snooping on the Switch. Enter igmp-snooping and press [ENTER]. You can also set how to treat traffic from an unknown multicast group by typing the unknown- multicast-frame parameter.

Syntax:

igmp-snooping

igmp-snooping 8021p-priority <0-7> igmp-snooping host-timeout <1-16711450> igmp-snooping leave-timeout <1-16711450>

igmp-snooping unknown-multicast-frame <dropflooding> igmp-snooping reserved-multicast-group <dropflooding>

where

 

 

igmp-snooping

=

8021p-priority

=

Sets a priority level (0-7) to which the Switch changes the

 

 

priority in outgoing IGMP control packets.

host-timeout <1- 16711450>

leave-timeout <1- 16711450>

unknown-multicast- frame <dropflooding>

reserved-multicast- group <dropflooding>

=Specifies the time out period of the Switch with respect to IGMP report queries. If an IGMP report for a multicast group was not received for a host-timeout period, from a specific port, this port is deleted from the member list of that multicast group.

=Specifies the time that the Switch will wait for multicast members to respond to a leave report. If no response happens in the timeout period, the Switch deletes the port from the multicast group.
