Use this command to display IGMP (Internet Group Management Protocol) Snooping Querier information. Configured information is displayed whether IGMP Snooping Querier is enabled.
| Format | show igmpsnooping querier [{detail | vlan vlanid}] |
| Mode | Privileged EXEC |
When the optional argument vlanid is not used, the command displays the following information.
| Admin Mode | Whether IGMP Snooping Querier is active on the switch. |
| Admin Version | The version of IGMP that will be used while sending out the queries. |
| Querier Address | The IP Address which will be used in the IPv4 header while sending out IGMP queries. It can be configured using the appropriate command. |
| Query Interval | The amount of time in seconds that a Snooping Querier waits before sending out the periodic general query. |
| Querier Timeout | The amount of time to wait in the Non-Querier operational state before moving to a Querier state. |
When you specify a value for vlanid, the following additional information appears.
| VLAN Admin Mode | Whether iGMP Snooping Querier is active on the VLAN. |
| VLAN Operational State | Whether IGMP Snooping Querier is in “Querier” or “Non-Querier” state. When the switch is in Querier state, it will send out periodic general queries. When in Non-Querier state, it will wait for moving to Querier state and does not send out any queries. |
| VLAN Operational Max Response Time | The time to wait before removing a Leave from a host upon receiving a Leave request. This value is calculated dynamically from the Queries received from the network. If the Snooping Switch is in Querier state, then it is equal to the configured value. |
| Querier Election Participation | Whether the IGMP Snooping Querier participates in querier election if it discovers the presence of a querier in the VLAN. |
| Querier VLAN Address | The IP address will be used in the IPv4 header while sending out IGMP queries on this VLAN. It can be configured using the appropriate command. |

| Last Querier Address | The IP address of the most recent Querier from which a Query was received. |
| Last Querier Version | The IGMP version of the most recent Querier from which a Query was received on this VLAN. |
When the optional argument detail is used, the command shows the global information and the information for all Querier-enabled VLANs.
