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
