VLAN. It can be in any of the following states:
• Querier:
The snooping switch is the querier in the VLAN. The

equal to the configured querier query interval. If the snooping
switch sees a better querier in the VLAN, it moves to non-querier
mode.

The 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.

not operational on the VLAN or when the querier address is not
configured or the network management address is also not
configured.
