show igmp snooping querier This command displays IGMP Snooping Querier information. Configured information is displayed whether or not IGMP Snooping Querier is enabled. When the optional argument vlan_id is not used, the command shows the following information: • Admin Mode - Indicates whether or not IGMP Snooping Querier is active on the switch. • Admin Version - Indicates the version of IGMP that will be used while sending out the queries. • Source IP Address - Shows the IP address that is used in the IPv4 header when sending out IGMP queries. It can be configured using the appropriate command. • Query Interval - Shows the amount of time in seconds that a Snooping Querier waits before sending out the periodic general query • Querier Timeout - Displays the amount of time to wait in the Non-Querier operational state before moving to a Querier state. When you specify a value for vlan_id, the following information appears: • VLAN Admin Mode - Indicates whether IGMP Snooping Querier is active on the VLAN. • VLAN Operational State - Indicates whether IGMP Snooping Querier is in the Querier or Non-Querier state. When the switch is in Querier state it sends out periodic general queries. When in Non-Querier state it waits for moving to Querier state and does not send out any queries. • VLAN Operational Max Response Time - Indicates 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 Participate - Indicates whether the IGMP Snooping Querier participates in querier election if it discovers the presence of a querier in the VLAN. • Last Querier Address - Indicates the IP address of the most recent Querier from which a Query was received. • Last Querier Version - Indicates the IGMP version of the most recent Querier from which a Query was received on this VLAN. • Elected Querier - Indicates the IP address of the Querier that has been designated as the Querier based on its source IP address. This field will be 0.0.0.0 when Querier Election Participate mode is disabled When the optional argument detail is used, the command shows the global information and the information for all Querier enabled VLANs.
