The MAC Address screen displays all MAC addresses learned by the Catalyst 1800 switch and on which port they were learned. You can select whether you want to display all ports or just one.
If all addresses cannot fit on a single screen, a message appears, stating "more addresses are available." If you reenter a MAC address that was previously displayed, the display resumes where it had left off at the previously issued command.
Type the monitor mac command from the Main menu. It can be abbreviated:
m m port_number
where port_number can either be 0 for all ports or a specific port number. Depending on your system, this number can be between 1 and 8, 1 and 12, or 1 and 16.
The MAC Address Database screen appears. In this example, the user typed 0 to monitor all ports:
Cisco Systems Catalyst 1800 Token Ring SwitchThe following table describes the entries on this screen.
| Parameter | Description |
|---|---|
| Port | The number of the port on which the MAC address was learned |
| Addr | The MAC address |

The Token Ring Physical Port Statistics screen displays 802.5 MAC layer statistics for the selected port.
Step 1 Type the monitor physical command from the Main menu. It can be abbreviated:
m p
The system responds:
Step 2 Enter the port number and press Return.
If the port you specified is a Token Ring port, the Token Ring Physical Ports Statistics screen appears. The first example shows the screen for Token Ring ports, and the second example (after the table) shows the screen for FDDI ports.
