User Guidelines
When IGMP report suppression is enabled, the switch only sends the first
report received for a group in response to a query. Report suppression is only
applicable to IGMPv1 and IGMPv2.
Example
The following example sets the snooping report suppressions time to 10
seconds.
console(config)#ip igmp snooping vlan 10 report-suppression
ip igmp snooping unregistered floodall
This command enables flooding of unregistered multicast traffic to all ports
in the VLAN. Use the no form of this command to only flood unregistered
multicast traffic to multicast router ports.
Syntax
ip igmp snooping unregistered floodall
no ip igmp snooping unregistered floodall
Default Configuration
Unregistered multicast traffic is only flooded to router ports by default. If no
mrouter ports are configured, or IGMP snooping cannot identify a multicast
router, then unregistered multicast is flooded to all ports in the VLAN.
Command Mode
Global Configuration mode.
