IGMP Snooping Querier VLAN Status Fields Field VLAN ID Operational State Operational Version Last Querier Address Description Specifies the VLAN ID on which the IGMP Snooping Querier is administratively enabled and for which VLAN exists in the VLAN database. Specifies the operational state of the IGMP Snooping Querier on a VLAN: • Querier: The snooping switch is the querier in the VLAN. The snooping switch will send out periodic queries with a time interval equal to the configured querier query interval. If the snooping switch sees a better querier (numerically lower) in the VLAN, it moves to nonquerier mode. • Non-Querier: The snooping switch is in non-querier mode in the VLAN. If the querier expiry interval timer expires, the snooping switch moves into querier mode. • Disabled: The snooping querier is not operational on the VLAN. The snooping querier moves to disabled mode when IGMP snooping is not operational on the VLAN, when the querier address is not configured, or the network management address is not configured. Displays the IGMP protocol version of the operational querier. Displays the IP address of the last querier from which a query was snooped on the VLAN. 3-46 v1.0, July 2009 Configuring Switching Information

Field
Description
VLAN ID
Specifies the VLAN ID on which the IGMP Snooping Querier is
administratively enabled and for which VLAN exists in the VLAN
database.
Operational State
Specifies the operational state of the IGMP Snooping Querier on a
VLAN:
Querier
: The snooping switch is the querier in the VLAN. The
snooping switch will send out periodic queries with a time interval
equal to the configured querier query interval. If the snooping switch
sees a better querier (numerically lower) in the VLAN, it moves to non-
querier mode.
Non-Querier
: The snooping switch is in non-querier mode in the
VLAN. If the querier expiry interval timer expires, the snooping switch
moves into querier mode.
Disabled
: The snooping querier is not operational on the VLAN. The
snooping querier moves to disabled mode when IGMP snooping is not
operational on the VLAN, when the querier address is not configured,
or the network management address is not configured.
Operational Version
Displays the IGMP protocol version of the operational querier.
Last Querier Address
Displays the IP address of the last querier from which a query was
snooped on the VLAN.
