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.
To define static addresses:
