User Guidelines
IGMP snooping can be enabled on Ethernet interfaces.
Example
The following example enables IGMP snooping.
console(config-if-1/g1)#ip igmp snooping
ip igmp snooping host-time-out
Use the ip igmp snooping host-time-out command in Interface Configuration mode to configure the
host-time-out. If an IGMP report for a Multicast group is not received for a host time-out period from a
specific port, this port is deleted from the member list of that Multicast group. To reset to the default
host time-out, use the no form of this command.
Syntax
time-out
ip igmp snooping host-time-out
no ip igmp snooping host-time-out
time-out — Host timeout in seconds. (Range: 2- 3600)
•
Default Configuration
The default host-time-out is 260 seconds.
Command Mode
Interface Configuration (Ethernet, port-channel) mode
User Guidelines
The timeout should be more than sum of response time and twice the query interval.
Example
The following example configures the host timeout to 300 seconds.
console(config-if-1/g1)#ip igmp snooping host-time-out 300
ip igmp snooping leave-time-out
Use the ip igmp snooping leave-time-out command in Interface Configuration mode to configure the
leave-time-out. If an IGMP report for a Multicast group is not received within the leave-time-out period
after an IGMP leave was received from a specific port, the current port is deleted from the member list of
that Multicast group. To configure the default leave-time-out, use the no form of this command.
