Address Tables
This section describes how MAC addresses are handled on the device.
It contains the following topics:
•Overview
• Static Address Table
• Dynamic Address Table
Overview
MAC addresses, associated with ports, are stored in the Static Address or the
Dynamic Address tables. Packets, addressed to a destination stored in one of
these tables, are forwarded to the associated port.
MAC addresses are dynamically learned when packets arrive at the device.
Addresses are associated with ports by learning the source address of the
frame. Frames, addressed to a destination MAC address that is not associated
with any port, are flooded to all ports of the relevant VLAN. In order to
prevent the bridging table from overflowing, dynamic MAC addresses, from
which no traffic is seen for a certain period, are erased.
Static addresses are manually entered into the table.
Static Address Table
Static addresses are manually assigned to a specific interface and VLAN on
the switch. If a static address is seen on another interface, the address is
ignored and it is not written to the address table.
To define a static address:
1
Click Switching > Address Tables > Static Address Table in the tree view
to display the
Static Address Table: Summary page.
A list of the currently-defined static addresses is displayed.
