query-interval:
This command configures the interval between two consecutive general
QUERIES sent out by the IGMP subsystem on this SAP.
configure service vpls service-id sap sap-id igmp-snooping query-interval
seconds
The configured query-interval must be greater than the configured
query-response-interval.
If send-queries is not enabled on this SAP, the configured query-interval value
has no effect.
The no form of this command returns the query-interval to its default value.
• query-response-interval:
This command configures the maximum time that (the IGMP subsystem on) an
SAP waits for an IGMP response after sending an IGMP QUERY.
configure service vpls service-id sap sap-id igmp-snooping
query-response-interval seconds
The system assumes a branch can be deleted when no RESPONSE is received
during a period of (robust_count-1)
× query_interval + query_response_interval.
If send-queries is not enabled on this SAP, the configured
query-response-interval value has no effect.
The no form of this command returns the query-response-interval to its default
value.
• last-member-query-interval:
This command configures the maximum time that (the IGMP subsystem on) an
SAP waits for an IGMP response after sending an IGMP group-specific query.
The latter was triggered by receiving an IGMP leave.
configure service vpls service-id sap sap-id igmp-snooping
last-member-query-interval interval
If fast-leave is enabled on the SAP, the configured last-member-query-interval
has no effect.
The no form of this command returns the last-member-query-interval to its default
value.
• robust-count:
This command configures the retry count for sending IGMP QUERIES, when an
IGMP response is not received/time-out.
configure service vpls service-id sap sap-id igmp-snooping robust-count
count
For example, when robust-count is 2, the system assumes a branch can be
deleted when no RESPONSE during a period of 1
× query_interval +
query_response_interval
If send-queries is not enabled on this SAP, the configured robust-count value has
no effect.
The no form of this command returns the robust-count to its default value.
