In Igmp snooping switch receives an Igmp leave report? Is it possible to change the timeout value in Igmp snooping switch?
We should be able to configure member leave time in the switch.
For Cisco boxes, we can configured this timer globally or on a vlan-basis: http://www.cisco.com/en/US/docs/switches/lan/catalyst4500/12.2/50sg/configuration/guide/multi.html#wp1126514 .
##To configure globally ip igmp snooping last-member-query-interval time ##To configure on a per-vlan basis: ip igmp snooping vlan vlan_ID last-member-query-interval time
Juniper boxes also support this feature: http://www.juniper.net/techpubs/en_US/junos/topics/task/configuration/igmp-snooping-ex-series-cli.html
I would recommend doing some more Google.
