Defining Address Tables
MAC addresses are stored in either the Static Address or the Dynamic Address databases. A packet
addressed to a destination stored in one of the databases is forwarded immediately to the port. The
Dynamic Address Table can be sorted by interface, VLAN, and MAC Address. MAC addresses are
dynamically learned as packets from sources arrive at the device. Addresses are associated with
ports by learning the ports from the frames source address. Frames addressed to a destination MAC
address that is not associated with any port, are flooded to all ports of the relevant VLAN. Static
addresses are manually configured. In order to prevent the bridging table from overflowing,
dynamic MAC addresses, from which no traffic is seen for a certain period, are erased.
This section contains information for defining both static and dynamic Forwarding Database entries,
and includes the following topics:
• Defining Static Addresses
• Defining Dynamic Addresses
Defining Static Addresses
A static address can be assigned to a specific interface on this switch. Static addresses are bound to
the assigned interface and cannot be moved. When a static address is seen on another interface,
the address will be ignored and will not be written to the address table.
