| into querier mode. |
| • Disabled: The snooping querier is not operational on the VLAN. The |

| operational on the VLAN, when the querier address is not configured, or |
| the network management address is 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 folder contains links to the following features:
•MAC Address Table on page 122
•Dynamic Address Configuration on page 124
•Static MAC Address on page 125
MAC Address Table
The MAC Address Table contains information about unicast entries for which the switch has forwarding and/or filtering information. This information is used by the transparent bridging function in determining how to propagate a received frame. Use the search function of the MAC Address Table page to display information about the entries in the table.
