onu-protocol igmp-snooping

Syntax
onu-protocol igmp-snooping { host-aging-time host-aging-time | leave-aggregation enable |
max-response-time
router-aging-time }
undo onu-protocol
max-response-time | report-aggregation enable | router-aging-time }
View
ONU port view
Default Level
2: System level
Parameters
host-aging-time: Aging time of multicast group member port, in seconds. It is in the range 200 to 1000
and defaults to 260.
leave-aggregation enable: Enables IGMP leave message suppression.
max-response-time: Maximum response time (in seconds) of group-specific queries. It is in the range 1
to 25 and defaults to 1.
report-aggregation enable: Enables IGMP report message suppression
router-aging-time: Router port aging time, in seconds. It is in the range 1 to 1000 and defaults to 105.
The max-response-time keyword in the onu-protocol igmp-snooping command sets the maximum
response time of the group-specific queries. If the device receives no response at the first timeout of the
maximum response time, it re-sends group-specific queries. If the device still receives no response
within the maximum response time, the multicast group on the corresponding ONU is deleted.
Description
Use the onu-protocol igmp-snooping command to configure IGMP snooping-related timers and
IGMP membership report suppression.
Use the undo onu-protocol igmp-snooping command to restore the defaults.
By default, IGMP join suppression is disabled, while IGMP leave suppression is enabled.
Note the following:
The aging time of multicast group member ports determines how often multicast group members
are refreshed. In an environment where multicast group members change frequently, a relatively
shorter aging time is required.
