Supported on all 7210 SAS platforms as described in this document, including those operating in access-uplink mode
This command creates a text description stored in the configuration file for a configuration context. The description command associates a text string with a configuration context to help identify the content in the configuration file.
The no form of this command removes the string from the configuration.
no description
Specifies the description character string. Allowed values are any string up to 80 characters composed of printable, 7-bit ASCII characters. If the string contains special characters (#, $, spaces, etc.), the entire string must be enclosed within double quotes.
[no] fast-leave
config>service>vpls>sap>igmp-snooping
Supported on all 7210 SAS platforms as described in this document, including those operating in access-uplink mode
This command enables fast leave. When IGMP fast leave processing is enabled, the 7210 SAS immediately removes a SAP or SDP from the multicast group when it detects an IGMP ‟leave” on that SAP or SDP. Fast leave processing allows the switch to remove a SAP or SDP that sends a 'leave' from the forwarding table without first sending out group-specific queries to the SAP or SDP, and therefore speeds up the process of changing channels ('zapping').
Fast leave should only be enabled when there is a single receiver present on the SAP or SDP. When fast leave is enabled, the configured last-member-query-interval value is ignored.

Supported on all 7210 SAS platforms as described in this document, including those operating in access-uplink mode
This command specifies whether a multicast router is attached behind this SAP or SDP.
Configuring a SAP or SDP as an mrouter-port has a double effect. First, all multicast traffic received on another SAP or SDP is copied to this SAP or SDP. Second, IGMP reports generated by the system as a result of someone joining or leaving a multicast group are sent to this SAP or SDP.
If two multicast routers exist in the network, one of them becomes the active querier. Even though the other multicast router (non-querier) stops sending IGMP queries, it still receives reports to keep its multicast trees up to date. To support this, the mrouter-port command should be enabled on all SAPs or SDPs connecting to a multicast router.
Note that the IGMP version to be used for the reports (v1or v2) can only be determined after an initial query has been received. Until then, no reports are sent on the SAP or SDP, even if mrouter-port is enabled.]
If the send-queries command is enabled on this SAP, the mrouter-port parameter cannot be set.

If the send-queries command is enabled, this parameter allows tuning for the expected packet loss on a SAP or SDP. The robust-count variable allows tuning for the expected packet loss on a subnet and is comparable to a retry count. If this SAP or SDP is expected to be 'lossy', this parameter may be increased. IGMP snooping on this SAP or SDP is robust to (robust-count-1) packet losses.
If send-queries is not enabled, this parameter is ignored.

This command specifies the version of IGMP which is running on this SAP or SDP. This object can be used to configure a router capable of running either value. For IGMP to function correctly, all routers on a LAN must be configured to run the same version of IGMP on that LAN.
When the send-query command is configured, all query types generated locally are of the configured version. If a report of a version higher than the configured version is received, the report gets dropped and the ‟wrong version” counter is incremented.
If the send-query command is not configured, the version command has no effect. The version used on that SAP is the version of the querier.
IGMPv3 is only supported on 7210 SAS platforms operating in access-uplink mode, or in an R-VPLS on 7210 SAS platforms operating in network mode.
Specifies the IGMP version.
