UMN:CLI User ManualV5812G332To display the IGMP static join group list, use the following command.Command Mode Descriptionshow ip igmp static-groupEnableGlobalBridgeShows the IGMP static join group list.1-99: IP standard access list1300-1999: IP standard access list (extended range)WORD: access list nameVLANS: VLAN ID (1-4094)show ip igmp static-group listshow ip igmp static-group list{<1-99> | <1300-1999> | WORD}[vlan VLAN]If you do not specify the reporter option, the IP address configured on the VLAN is usedas the source address of the membership report by default. If no IP address is configuredon the VLAN, 0.0.0.0 is then used.This feature only supports an IGMPv2 host; it does not support IGMPv3 host.9.1.2.2 IGMP Access ControlMulticast routers send membership query messages to determine which multicast groupshave members in the attached local networks of the router. If hosts respond to the queries,the routers then forward all packets addressed to the multicast group to these groupmembers. You can restrict hosts on a network to join multicast groups on the specifiedaccess list.To control an access to multicast groups on an interface, use the following command.Command Mode Descriptionip igmp access-group {<1-99> |WORD} InterfaceEnables an IGMP access control on an interface.1-99: IP standard access listWORD: access list nameno ip igmp access-group Disables a configured IGMP access control.9.1.2.3 IGMP Querier ConfigurationAn IGMP querier is the only router that sends membership query messages for a networksegment. In IGMP version 2, the querier is a router with the lowest IP address on thesubnet. If the router hears no queries for the timeout period, it becomes the querier.IGMP Query IntervalThe querier (a multicast router) sends general query messages periodically to discoverwhich multicast groups have members on the attached networks of the router.To specify an interval to send general query messages, use the following command.Command Mode Descriptionip igmp query-interval<1-18000> InterfaceSpecifies a general query interval.1-18000: query interval (default: 125 seconds)no ip igmp query-interval Deletes a specified general query interval.!i
