The Configuring Ports menu allows you to choose between configuring port priority or selecting a port with which to use the switched port analyzer (SPAN). This procedure is also known as port mirroring.
To use the Port Configuration menu, type the following from the Main menu:
con port
The Port Configuration menu appears, listing the options you can access:
Cisco Systems Catalyst 1800 Token Ring Switch
Select From
Priority
SPAN
Catalyst 1800> con port
From this menu you can configure SPAN ports and set port priority. Refer to the subsequent sections.
You can configure a SPAN port that reflects the LLC (Logical Link Control) traffic found on another switched port. This feature is useful if you want to monitor the traffic on a specific port. The mirror port is called the SPAN port, while the port being mirrored is the port to monitor. Any one of the 16 switch ports can be designated as either port.
For example, a company wants to monitor the traffic coming over port 4, so they designate port 8 as the SPAN port for port 4. They attach a network analyzer to port 8 allowing any traffic that comes over port 4 to be reflected in the network analyzer.
The following conditions apply to SPAN:
The following sections show how to configure and delete a SPAN port.
Step 1 To configure a SPAN port, type this command:
con port span
The SPAN Port Configuration screen appears and the following message appears:
Enter SPAN port, port to analyze
Cisco Systems Catalyst 1800 Token Ring Switch
SPAN Port Configuration
Port to Monitor SPAN Port
-------------- ---------
4 8
Catalyst 1800>con port span
Step 2 Enter the number of the port you want to mirror and press Return.
The system displays the following message:
Enter SPAN Port, port attached to analyzer (0 to delete)
Step 3 Enter the number of the port that you want to be the SPAN port and press Return. The SPAN port now mirrors the LLC traffic on the port being monitored.
You may want to delete a SPAN port to free up the destination port so that it can accept switched traffic. Perform this procedure.
Step 1 Type this command:
Configure Port SPAN
The SPAN Port Configuration menu appears (shown at the beginning of this section) and the system displays the following message:
Enter port to monitor (0 to delete)
Step 2 Type 0.
Enter SPAN Port, port attached to analyzer (0 to delete)
Step 3 Type 0 press Return. The SPAN port is now deleted. No port numbers appear in the Port to Monitor and the SPAN Port fields.
The Port Priority menu allows you to configure priority levels for each port. Port prioritizing is based on a scale from 1 to 100. Ports assigned higher values receive higher priority.
Step 1 Type this command from the Main menu:
Configure Port Priority
The Port Priority Configuration menu appears:

If a read/write community name has been entered, read-only community names are no longer be accepted as the password. |
Access | The access mode for any SNMP manager using the associated community name. Valid values are RO (read-only) and RW (read-write). If a community name is given RW access, it will also be a valid switch password. |
Trap IP Address | When the Catalyst 1800 switch encounters an event that must be reported to an SNMP manager, this address is used to send that event (trap). If this address is configured to 0.0.0.0, the Catalyst 1800 switch discards a notification about all traps. |

Use the TFTP option on the Configuration menu
The Trivial FTP (TFTP) is a simplified form of FTP (file transfer protocol) that does not require a login interaction.
You must specify the IP address of a file server that is appropriately configured to support TFTP access.
Step 1 Type this command from the Main menu:
c t
The TFTP Configuration menu appears:
Cisco Systems Catalyst 1800 Token Ring/FDDI Uplink
Select From
Server IP
Software Image
Upload Config
Download Config
Catalyst 1800> c t
Step 2 The first part of the command, c t, is echoed at the prompt. Type se and the system displays the following message:
Enter TFTP Server's IP Address.
Step 3 Enter the IP address of the TFTP server. The Configuration menu reappears.
To download an operational software image file from a TFTP server to the Catalyst 1800 switch, use the Software Images selection on the TFTP Configuration menu.
There are two different software image files, one for the FDDI uplink module and one for the Token Ring module. The following procedure assumes you have two boards installed. If you have only one board installed, the software prompts you for only one filename.
In the previous release, it was necessary to upload the image through the serial port on the switch. This procedure is still available for offline downloading. For more information, refer to the section "Upgrading to New Software Releases through the Serial Port" in the appendix "Installation and Maintenance."
The steps to download an operational software image file from a TFTP server to the Catalyst 1800 switch are:
Step 1 Type c t at the Main menu and the TFTP Configuration menu appears:

The following table describes the parameters on the TFTP Configuration screen.
| Parameter | Description |
|---|---|
TFTP Server | The IP address of the TFTP server containing the image file(s), expressed in standard IP address format (xxx.xxx.xxx.xxx) |
(Lower) B1 SW Image Filename | The software image filename residing on the TFTP server. Ordinarily, this image file is used for the FDU board in the Catalyst 1800 switch. In 16 port Token Ring systems, both B1 and B2 use the same TR filename. |
(Upper) B2 SW Image Filename | The software image filename residing on the TFTP server. Ordinarily, this image file is used for the Token Ring board in the Catalyst 1800 switch. |
Download Results | The results of the latest software image download session for a module. This field can be one of the following:

Step 4 Type c t so filename and The system displays the following message:
Enter Board number 1 (lower) or 2 (upper)
Step 5 Enter the software image filename for the lower board in the Catalyst 1800 chassis and press Return. Typically, this is the FDDI module.
If the file is not on the root directory of the TFTP server, enter the whole pathname, with a maximum of 16 characters. If you type more than 16 characters, the system does not perform the procedure.
The system displays the following message:
Enter Filename to Download
Step 6 Enter the software image filename for the upper board in the Catalyst 1800 chassis and press Return. Typically, this is the Token Ring module.
