MAC Management

7.1 Overview

Use these screens to add, delete and view entries in the MAC address table.

The MAC Table (a MAC table is also known as a filtering database) shows how frames are forwarded or filtered across the Switch’s ports. When a device (which may belong to a VLAN group) sends a packet which is forwarded to a port on the Switch, the MAC address of the device is shown on the Switch’s MAC Table. It also shows whether the MAC address is dynamic (learned by the Switch) or static (manually entered).

7.2What You Can Do

•Use the Static MAC Settings screen (Section 7.4 on page 52) to manually add a static MAC address to the table.

•Use the MAC Table screen (Section 7.5 on page 53) to view the static and dynamic MAC address entries.

7.3What You Need to Know

The Switch uses the MAC Table to determine how to forward frames. See the following figure.

1The Switch examines a received frame and learns the port from which this source MAC address came.

2The Switch checks to see if the frame's destination MAC address matches a source MAC address already learned in the MAC Table.

•If the Switch has already learned the port for this MAC address, then it forwards the frame to that port.
