CHAPTER 7
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).
7.2 What 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.
7.3 What You Need to Know
The Switch uses the MAC Table to determine how to forward frames. See the
following figure.
1 The Switch examines a received frame and learns the port from which this source
MAC address came.
2 The 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.
