Section8.4.3.1
Configuring IGMP Snooping
To configure IGMP snooping, do the following:
1. Make sure the CLI is in Configuration mode.
2. Navigate to switch» mcast-filtering» igmp-snooping and configure the following parameter(s) as required:
Parameter Description
igmp-mode { igmp-mode } Synopsis:  { active, passive }
Default:  passive
Specifies the IGMP mode:
• PASSIVE : The switch passively snoops IGMP traffic and never sends IGMP queries.
• ACTIVE : The switch generates IGMP queries, if no queries from a better candidate for
the querier are detected for a while.
igmp-query-interval { igmp-query-interval } Synopsis:  A 32-bit signed integer between 10 and 3600
Default:  60
The time interval between IGMP queries generated by the switch. NOTE: This parameter
also affects the Group Membership Interval (i.e. the group subscriber aging time),
therefore, it takes effect even in PASSIVE mode.
router-forwarding Synopsis:  { true, false }
Default:  true
Whether or not multicast streams will always be forwarded to multicast routers.
rstp-flooding Whether or not multicast streams will be flooded out of all Rapid Spanning Tree Protocol
(RSTP) non-edge ports upon detection of a topology change. Such flooding is desirable, if
multicast stream delivery must be guaranteed without interruption.
3. Assign one or more ports for IGMP to use when sending Membership Reports. For more information, refer to
Section8.4.3.3, “Adding a Router Port”.
4. Type commit and press Enter to save the changes, or type revert and press Enter to abort.
Section8.4.3.2
Viewing a List of Router Ports
To view a list of router ports used for IGMP snooping, type:
show running-config switch mcast-filtering igmp-snooping router-ports
If router ports have been configured, a table or list similar to the following example appears:
ruggedcom# show running-config switch mcast-filtering igmp-snooping router-ports | tab

If no router ports have been configured, add ports as needed. For more information, refer to Section8.4.3.3,
“Adding a Router Port”.
