ip igmp robust <2-10>
Configures the IGMP Robustness variable, which allows you to tune the switch for expected
packet loss on the subnet. If the subnet is expected to be lossy (high rate of packet loss),
increase the value. The default value is 2.
Command mode: Global configuration
[no] ip igmp flood
Configures the switch to flood unregistered IP multicast traffic to all ports. The default setting
is enabled.
Note: If none of the IGMP hosts reside on the VLAN of the streaming server for a IPMC
group, you must disable IGMP flooding to ensure that multicast data is forwarded across the
VLANs for that IPMC group.
Command mode: Global configuration
[no] ip igmp cpu
Configures the switch to forward unregistered IP multicast traffic to the MP, which adds an
entry in the IPMC table, as follows:
 If no Mrouter is present, drop subsequent packets with same IPMC.
 If an Mrouter is present, forward subsequent packets to the Mrouter(s) on the ingress
VLAN.
The default setting is enabled.
Note: If both flood and cpu are disabled, then the switch drops all unregistered IPMC
traffic.
Command mode: Global configuration
[no] ip igmp aggregate
Enables or disables IGMP Membership Report aggregation.
Command mode: Global configuration
ip igmp snoop source-ip <IP address>
Configures the source IP address used as a proxy for IGMP Group Specific Queries.
