Some hints about IGMP basics:
show ip igmp config
show ip igmp vlan <vid> config
show ip igmp statistics
show ip igmp groups
show ip igmp vlan <vid> group <ip-addr>
show ip igmp <vid>show ip igmp config
show ip igmp vlan <vid> config
show ip igmp statistics
show ip igmp groups
show ip igmp vlan <vid> group <ip-addr>
Enable
HP Switch(vlan-1)# vlan 1 ip igmp
HP Switch(vlan-1)# ip igmp
Disable
no ip igmpno vlan 1 ip igmp
Example:
Ports 1-2 auto Filter multicast traffic. Forward IGMP traffic to hosts on these ports that belong to the multicast group for which the traffic is intended. (Also forward any multicast traffic through any of these ports that is connected to a multicast router.) Ports 3-4 forward Forward all multicast traffic through this port. Ports 5-6 blocked Drop all multicast traffic received from devices on these ports.
Configuring static multicast groups
Use this command to configure a group on the switch so that multicast traffic for that group can be forwarded with a receiver host. Traffic will be flooded for this group.
