The Catalyst 1600 Token Ring switch supports serial management and Telnet sessions, and provides a simple command-line interface that you can use to configure the Catalyst 1600 before connecting other network devices.
To manage the Catalyst 1600 using the serial interface, connect one of the following devices to the serial port on the front panel (see Figure 1-1):
When you connect the terminal to the Catalyst 1600:
Pin Connections for the Serial Port
Figure 4-1 illustrates the pin connections to use when you connect the Catalyst 1600 to a terminal using a null-modem EIA/TIA-232 cable, or to a modem using a straight-through EIA/TIA-232 cable.
Figure 4-1 : Pin Connections for Catalyst 1600 Serial Port
When you connect to the serial interface using the Catalyst 1600 password, or when no password is set, you can gain access to read commands such as show bridge status and write commands such as set port ifmode.
If you do not enter the correct password, you can only enter read commands and you cannot change the configuration of the Catalyst 1600. If you have read-only access to the device, the help command displays only the commands that are available.
Whether you have read-only or read/write access to the Catalyst 1600, you can enter commands by typing only the first part of the command and pressing the space bar. Depending on the combination of command lines that can result from the part that you have entered, the remaining part of the command line is completed for you.
For example, to enter the command show bridge characteristics:
The command line The read-only commands that you can use without entering the Catalyst 1600 password are described below.
The read/write commands that you can use after entering the Catalyst 1600 password include all read-only commands, and the commands described below.
