Version 8.3.7.0 7.6.1.0 7.5.1.0 E-Series legacy command Description Introduced on the S4810. Introduced on the S-Series. Introduced on the C-Series. Usage Information This command enables the IGMP switch to send General Queries periodically. This behavior is useful when there is no multicast router present in the VLAN because the multicast traffic is not routed. Assign an IP address to the VLAN interface for the switch to act as a querier for this VLAN. show ip igmp snooping groups Display snooping related information for all the IGMP groups, interface or one group of one interface. Syntax Parameters show ip igmp snooping groups [group-address [detail] | detail | interface [group-address [detail]]] snooping group-address interface detail Enter the keyword snooping to display snooping related information. (OPTIONAL) Enter the group address in dotted decimal format to view information on that group only. (OPTIONAL) Enter the interface type and the interface information: • For a 1-GigabitEthernet interface, enter the keyword GigabitEthernet then the slot/port information. • For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port information. • For a Loopback interface, enter the keyword loopback then a number from 0 to 16383. • For a port channel interface, enter the keywords port-channel then a number. • For a VLAN interface, enter the keyword vlan then a number from 1 to 4094. (OPTIONAL) Enter the keyword detail to display the IGMPv3 source information. Command Modes • EXEC • EXEC Privilege Command History This guide is platform-specific. For command information about other platforms, see the relevant Dell Networking OS Command Line Reference Guide.
