Usage Guidelines
Use the show ip igmp snooping querier command to display the IGMP version and the IP address of a
detected device, also called a querier, that sends IGMP query messages. A subnet can have multiple multicast
routers but has only one IGMP querier. In a subnet running IGMPv2, one of the multicast routers is elected
as the querier. The querier can be a Layer 3 device.
The show ip igmp snooping querier command output also shows the VLAN and the interface on which the
querier was detected. If the querier is the device, the output shows the Port field as Router. If the querier is a
router, the output shows the port number on which the querier is learned in the Port field.
The show ip igmp snooping querier detail user EXEC command is similar to the show ip igmp snooping
querier command. However, the show ip igmp snooping querier command displays only the device IP
address most recently detected by the device querier.
The show ip igmp snooping querier detail command displays the device IP address most recently detected
by the device querier and this additional information:
•
The elected IGMP querier in the VLAN
•
The configuration and operational information pertaining to the device querier (if any) that is configured
in the VLAN
Expressions are case sensitive. For example, if you enter | exclude output, the lines that contain output do not
appear, but the lines that contain Output appear.
