Explicit Host Tracking
This capability enables the Switch to track each individual host that is joined to a particular group
or channel and to achieve minimal leave latencies when hosts leave a multicast group or channel.
Notice:
Before configuring the ip igmp explicit-tracking command, IGMP must be enabled.
When explicit host tracking is enabled, the router uses more memory than if explicit tracking is
disabled because the router must store the membership state of all hosts on the interface.
