Operational State

Specifies the operational state of the IGMP Snooping Querier on a 
VLAN:
•

. 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.

•

. 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.

•

. The 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.

Forwarding Database

The forwarding database maintains a list of MAC addresses after having received a packet 
from this MAC address. The transparent bridging function uses the forwarding database 
entries to determine how to forward a received frame.

The Address Table link contains links described in the following sections.
