This command enables the Internet Group Management Protocol (IGMP) router alert check option.
The no form of this command disables the router alert check.

config>service>vpls>igmp-snooping>mvr
Supported on all 7210 SAS platforms as described in this document
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.
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
This command enables fast leave. When the IGMP fast leave processing is enabled, the 7210 SAS immediately removes a SAP from the multicast group when it detects an IGMP ‟leave” on that SAP.
Fast-leave processing allows the switch to remove a SAP that sends a ‟leave” from the forwarding table without first sending out group-specific queries to the SAP, 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.
When fast-leave is enabled, the configured last-member-query-interval value is ignored.

This command configures the VPLS from which multicast traffic is copied upon receipt of an IGMP join request. IGMP snooping must be enabled on the MVR VPLS.
no from-vpls
Specifies the MVR VPLS from which multicast channels should be copied into this SAP.
[no] group grp-address
config>service>vpls>sap>igmp-snooping>static
Supported on all 7210 SAS platforms as described in this document
This command adds a static multicast group as a (*, g). When a static IGMP group is added, multicast data for that (*,g) or (s,g) is forwarded to the specific SAP without receiving any membership report from a host.
Specifies an IGMP multicast group address that receives data on an interface. The IP address must be unique for each static group.

This command identifies filter policy of multicast groups to be applied to this VPLS entity. The sources of the multicast traffic must be a member of the VPLS. By default, no group policy is identified.
The no form of this command removes the policy association from the VPLS configuration.
Specifies the group policy name. Allowed values are any string up to 32 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. Routing policies are configured in the config>router>policy-options context. The router policy must be defined before it can be imported.

This command configures the maximum response time used in group-specific queries sent in response to ‟leave” messages and is also the amount of time between 2 consecutive group-specific queries. This value may be tuned to modify the leave latency of the network. A reduced value results in reduced time to detect the loss of the last member of a group.

This command configues whether a multicast router is attached behind this SAP.
Configuring a SAP or SDP as an mrouter-port has a double effect. Firstly, all multicast traffic received on another SAP or SDP is copied to this SAP or SDP. Secondly, 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. While the other multicast router (non-querier) stops sending IGMP queries, it should still receive 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.
The IGMP version to be used for the reports (v1or v2) can only be determined after an initial query has been received. Until that time, no reports are sent on the SAP, even if mrouter-port is enabled.
If the send-queries command is enabled on this SAP or SDP, the mrouter-port command cannot be configured.

If the send-queries command is enabled, this command allows tuning for the expected packet loss on a SAP or SDP. The robust-count value 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 command is ignored.

This command configures whether to send IGMP general query messages on the SAP or SDP.
When the send-queries command is configured, all query reports generated locally are of the type belonging to the configured version. If a report of a version higher than the configured version is received, the report is dropped and a new counter to track the wrong version is incremented.

This command specifies the version of IGMP that is running on this SAP. 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-queries command is configured, all query reports generated locally are of the type belonging to the configured version. If a report of a version higher than the configured version is received, the report is dropped and a new counter to track the wrong version is incremented.
