Task Command Display IGMP SSM mappings. display igmp ssm-mapping group-address [ | { begin | exclude | include } regular-expression ] Available in any view. Display the multicast group information created from IGMPv1 and IGMPv2 reports based on the configured IGMP SSM mappings. display igmp ssm-mapping group [ group-address | interface interface-type interface-number ] [ verbose ] [ | { begin | exclude | include } regular-expression ] Available in any view. Remove all the dynamic IGMP group entries of IGMP groups. reset igmp group { all | interface interface-type interface-number { all | group-address [ mask { mask | mask-length } ] [ source-address [ mask { mask | mask-length } ] ] } } Available in user view. This command cannot remove static IGMP group entries. Remove all the dynamic Layer 2 port entries of IGMP groups. reset igmp group port-info { all | group-address } [ vlan vlan-id ] Available in user view. Clear IGMP SSM mappings. reset igmp ssm-mapping group { all | interface interface-type interface-number { all | group-address [ mask { mask | mask-length } ] [ source-address [ mask { mask | mask-length } ] ] } } Available in user view. IGMP configuration examples Basic IGMP functions configuration example Network requirements Receivers receive VOD information through multicast. Receivers of different organizations form stub networks N1 and N2, and Host A and Host C are receivers in N1 and N2 respectively. IGMPv2 runs between Switch A and N1. IGMPv2 runs between the other two switches and N2. Switch B acts as the IGMP querier in N2 because it has a lower IP address. The hosts in N1 can join only multicast group 224.1.1.1, and the hosts in N2 can join any multicast groups. 93
