Explicit Host Tracking - TRENDnet TI-PG1284i User Manual

TRENDnet User's Guide

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.
