How to Assign an IP Address to the Cisco Catalyst 2900Xl

Confige an IP address on a Cisco Catalyst 2900XL

Assigning an IP address to a managed network switch such as a Cisco Catalyst 2900XL enables an administrator to manage the network switch remotely. The advantage is huge: there is no need to plug in to the switch locally with a serial cable every time a configuration change is required. Adding an IP address to the switch configuration can be accomplished in a few steps.

Things You'll Need

• Cisco Catalyst serial console cable
• Computer with terminal console program and 9-pin serial port

Instructions

1. Plug the Cisco Catalyst serial console cable into the serial console port on the Cisco Catalyst 2900XL. Plug he other end of the serial console cable into the 9-pin serial port on the computer.

2. Open a terminal communications program on the computer (such as Hyperterminal or Putty if using Windows or Minicom if using Unix or Linux) and configure the program to communicate through the port in which the serial console cable is connected, using 9600 bits per second (entered into the "baud or "bps" settings) and flow control set to "None".

3. Press the "Enter" key a few times until the Cisco Catalyst command-line interface prompt appears.

4. Type "enable" and press the "Enter" key, then type the password to access "privileged exec" mode on the switch if requested.

5. Type "config t" and press the "Enter" key. Type "interface vlan1" and press the "Enter" key. Type "ip address 192.168.1.1 255.255.255.0" replacing "192.168.1.1 255.255.255.0" with the IP address and subnet mask intended for use on the Cisco Catalyst 2900XL, and then press the "Enter" key.

6. Type "exit" and then type "exit" again and then type "exit" again, each time followed by pressing the "Enter" key in order to end the configuration session.
