Description
Operational State
Displays the operational state of the IGMP snooping querier on a 
VLAN. It can be in any of the following states:
• 
Querier: The snooping switch is the querier in the VLAN. The 
snooping 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: 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. The 
snooping querier moves to disabled mode when IGMP snooping is 
not operational on the VLAN or when the querier address is not 
configured or the network management address is also not 
configured.

snooped on the VLAN.
