System Configuration 3-41

The IGMP V2/V3 Settings screen appears.

You can configure the following parameters:

Last Member Query Interval (deci-sec) – the amount of time in tenths of a second that the IGMP router
waits to receive a response to a Group-Specific Quer y message. The last member quer y inter val is also the
amount of time in seconds between successive Group-Specific Quer y messages. The default last member
quer y inter val is 1 second (10 deci-seconds).

Last Member Query Count – the number of Group-Specific Quer y messages sent before the router
assumes that there are no members of the host group being queried on this inter face. The default last
member quer y count is 2.

Fast Leave – Toggling this option to On enables a non-standard expedited leave mechanism. The querier
keeps track of which client is requesting which channel by IP address. When a leave message is received,
the querier can check its internal table to see if there are any more clients on this group. If there are none,
it immediately sends an IGMP leave message to the upstream querier. By default, Fast Leave is set to Off.

Press Escape twice to return to the System Configuration menu.
