Hi,


I have a doubt about the IGMP query interval. We experienced some problems regarding multicast behaviour in our network after we have configured the IGMP query interval at 30 seconds.


Anyone could tell me if could be problems when I configure that timer lower than 60 seconds?


Thank you very much.


Regards.


Giuseppe.

Configure the source IP on a per-VLAN basis by issuing the set igmp querier address vlan ip_addr command.


Note: Prior to CatOS 8.x for Catalyst 6500 series switches, there was no way to configure the source IP address on a per-VLAN basis. Since the IGMP querier needs a source IP, it used the source IP address as 0.0.0.0.
