Description: This is the interval (in seconds) after which a learnt host port entry will be purged.
For each host port learnt, a 'PortPurgeTimer' runs for 'HostPortPurgeInterval'.
This timer will be restarted whenever a report message from host is received over that port. If no report mssages are received for 'HostPortPurgeInterval' time, the learnt host entry will be purged from the multicast group.
What is igsHostPortPurgeInterval?
This sets how many seconds (130-153025, default 260) the switch waits without receiving a membership report from a host before purging that host's multicast group membership on a port. An admin would tune this alongside the IGMP query interval to control how quickly stale multicast subscribers are removed from the forwarding table.
