CONFIGURING THE SWITCH

Displaying the Address Table

The Dynamic Address Table contains the MAC addresses learned by monitoring the source address for traffic entering the switch. When the destination address for inbound traffic is found in the database, the packets intended for that address are forwarded directly to the associated port. Otherwise, the traffic is flooded to all ports.

Command Attributes

•Interface – Indicates a port or trunk.

•MAC Address – Physical address associated with this interface.

•VLAN – ID of configured VLAN (1-4094).

•Address Table Sort Key – You can sort the information displayed based on MAC address, VLAN or interface (port or trunk).

•Dynamic Address Counts – The number of addresses dynamically learned.

•Current Dynamic Address Table – Lists all the dynamic addresses.
