Field Description
VLANID 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.
