IGMP Snooping Commands 193
Example
The following example enables automatic learning of Multicast router ports on VLAN 2.
ip igmp snooping host-time-out
The ip igmp snooping host-time-out Interface Configuration (VLAN) mode command configures the
host-time-out. If an IGMP report for a Multicast group was not received for a host-time-out period from
a specific port, this port is deleted from the member list of that Multicast group. Use the no form of this
command to return to the default configuration.
