expression]
Syntax Description
Command Modes User EXEC
Command History
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 switch.
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 switch, 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 switch querier.
The show ip igmp snooping querier detail command displays the device IP address most recently
detected by the switch querier and this additional information:
• The elected IGMP querier in the VLAN
• The configuration and operational information pertaining to the switch 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.
detail Optional) Display detailed IGMP querier information.

range is 1 to 1001 and 1006 to 4094. Use the detail keyword to display
detailed information.
