When this mode is disabled, on detecting another querier of same version in the VLAN,
the snooping querier moves to a non-querier state. When this mode is enabled, the
snooping querier participates in querier election where the lowest IP address wins the
querier election and operates as the querier in that VLAN. The other querier moves to
non-querier state.

Operational State The operational state of the MLD snooping querier on a VLAN. It can be in
any of the following states:
• Querier: Snooping switch is the querier in the VLAN.

switch sends out periodic queries with a time interval equal to the
configured querier query interval. If the snooping switch sees a better
querier in the VLAN, it moves to non-querier mode.
• Non-Querier: Snooping switch is in non-querier mode in the VLAN. If
the querier expiry interval timer is expired, the snooping switch moves
into querier mode.
• Disabled: Snooping querier is not operational on the VLAN.
The
snooping querier moves to disabled mode when MLD snooping is not
operational on the VLAN or when the querier address is not configured
or the network management address is also not configured.
Operational Version The operational MLD protocol version of the querier.
Last Querier Address The IP address of the last querier from which a query was snooped on the
