Re: Re : Configuring a terminal server on a 2821 router .....
Follow these instructions to troubleshoot your configuration.
If you cannot connect to the router of your choice with a name configured in the ip host command check:
Check whether the port address is configured correctly.
Verify whether the address (interface) used for the reverse Telnet is up/up. The output of the show ip interface brief command provides this information. Cisco recommends you to use loopbacks because they are always up.
Ensure that you have the correct type of cabling. For example, you must not use a crossover cable to extend the length. Refer to the Cabling section for more information.
Establish a Telnet connection to the IP address port to test direct connectivity. You must telnet from both an external device and the terminal server. For example, telnet 172.21.1.1 2003.
Ensure that you have the transport input telnet command under the line for the target device. The target device is the device that is connected to the terminal server.
Use a PC/dumb terminal to connect directly to the console of the target router. The target router is the device connected to the terminal server. This step helps you identify the presence of a port issue.
If you are disconnected, check timeouts. You can remove or adjust timeouts.
Note: If you encounter authentication failures, remember that the terminal server performs the first authentication (if configured), while the device to which you try to connect performs the second authentication (if configured). Verify whether AAA is configured correctly on both the terminal server and the connecting device.
