Searching and Configuring the 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 folder contains links to the following features:
• “Searching the MAC Address Table” on page 3-50
• “Dynamic Address Configuration” on page 3-52
Table 3-32. IGMP Snooping Querier VLAN Status Fields
Field Description
VLAN ID 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.
Last Querier Version Displays the IGMP protocol version of the last querier from which a
