Variable
Value
Router Port Purge Interval
(secs)
Type the time interval for which the learnt router port is purged.
For each learnt router port, the timer runs for the configured port purge
time interval. When the timer expires, the learnt router port entry is purged.
If control messages are received from the router before the timer expiry,
then the timer restarts.
The value ranges from 60 to 600.
The default value is 125 seconds.
Group-Member Port Purge
Interval (secs)
Type the time interval after which a port is deleted, if IGMP reports are not
received on a port.
The timer runs for the configured time for each port on which a report is
received.
This timer restarts whenever a report message is received from a host on
the specific port. If the timer expires, the learnt port entry is purged from
the multicast group.
The value ranges from 130 to 1225.
The default value is 260 seconds.
Report Forward Interval (secs) Type the time interval within which the next report messages for the same
multicast group is not forwarded.
This timer is used when proxy reporting is disabled and the switch must
suppress multiple IGMPv2 report messages for the same group from
being forwarded to the router. The Report Forward Interval is configured
for each multicast group. This timer is started as soon as a report
message for that group is forwarded.
Within this Report Forward Interval, if another report for the same group
arrives, the report is not forwarded.
The value ranges from 1 to 25.
The default value is 5 seconds.
Group Query Interval (secs)
Type the interval within which the switch sends a group-specific query on
a port when an IGMPv2 leave message is received.
The value ranges from 2 to 5.
The default value is 2 seconds.
