  • I still don't understand what you need... please review this link about IGMP timers and let us know if you still have questions... Sep 30, 2013 at 10:25
  • Mike, he is talking about setting timers in the switch and not on individual hosts that send IGMP reports. I am going to edit the questions a little bit. Sep 30, 2013 at 15:27

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.

  • Please quote the relevant parts of those referenced documents. So when those URls break, your answer would still make sense. Sep 30, 2013 at 16:21
  • Fair point. I have added the relevant config. Sep 30, 2013 at 18:19
