Modifying IGMP snooping parameters for a SAP or SDP

Use the following CLI syntax to customize IGMP snooping parameters on an existing SAP. Commands for spoke or mesh SDPs are identical.

CLI syntax:

config>service# vpls service-id 
    sap sap-id
        igmp-snooping
            fast-leave     
            import policy-name 
            last-member-query-interval interval
            max-num-groups max-num-groups
            mrouter-port 
            query-interval interval
            query-response-interval interval
            robust-count count
            send-queries 

To enable and customize sending of IGMP queries to the hosts:

Example:

config>service# vpls 1 
    config>service>vpls# sap 1/1/3:0
    config>service>vpls>sap# igmp-snooping
    config>service>vpls>sap>snooping# send-queries
    config>service>vpls>sap>snooping# query-interval 100
    config>service>vpls>sap>snooping# query-response-interval 60
    config>service>vpls>sap>snooping# robust-count 5
    config>service>vpls>sap>snooping# exit
    config>service>vpls>sap# no shutdown

To customize the leave delay:

Example:

config>service# vpls 1 
    config>service>vpls# sap 1/1/1:1 
    config>service>vpls>sap# igmp-snooping
    config>service>vpls>sap>snooping# last-member-query-interval 10
    config>service>vpls>sap>snooping# no fast-leave
    config>service>vpls>sap>snooping# exit
    config>service>vpls>sap# exit

To enable Fast Leave:

Example:

config>service# vpls 1 
    config>service>vpls# sap 1/1/1:1 
    config>service>vpls>sap# igmp-snooping
    config>service>vpls>sap>snooping# no last-member-query-interval
    config>service>vpls>sap>snooping# fast-leave
    config>service>vpls>sap>snooping# exit
    config>service>vpls>sap# exit

To limit the number of streams that a host can join:

Example:

config>service# vpls 1 
    config>service>vpls# sap 1/1/1:1
    config>service>vpls>sap# igmp-snooping
    config>service>vpls>sap>snooping# max-num-groups 4
    config>service>vpls>sap>snooping# exit
    config>service>vpls>sap# exit

To enable sending group reports on a SAP to standby multicast routers:

Example:

config>service# vpls 1 
    config>service>vpls# sap 1/1/1:1
    config>service>vpls>sap# igmp-snooping
    config>service>vpls>sap>snooping# mrouter-port
    config>service>vpls>sap>snooping# exit
    config>service>vpls>sap# exit

The following example displays the modified IGMP snooping configuration on a SAP:

A:ALA-48>config>service>vpls>sap>snooping# info detail
----------------------------------------------
                    no fast-leave
                    no import
                    max-num-groups 4
                    last-member-query-interval 10
                    no mrouter-port
                    query-interval 100
                    query-response-interval 60
                    robust-count 5
                    send-queries
