This article uses the Cisco 2509 Terminal Server to log on to other machines. how to configure the server? The following article describes the configuration process in detail and provides configuration commands.
Use Cisco router reverse Telnet for Terminal Server
If we have multiple routers for experiment, it will be very troublesome to configure one Router Based on the control line. Therefore, we need to configure a terminal server to log on to other machines, the procedure is as follows:
Install the octopus cable in Cisco 2509, note that only the cable is installed, no DB25-RJ45 converter is required. Insert an RJ45 head of the octopus cable into the Console port of another Cisco device.
Then configure this 2509:
Line tty 1 8
No exec
Transport input all
If you want to log on to the Cisco device that is connected to tty1 (braid 1), it must be on Terminal Server 2509:
Telnet X. X 2001 (X. X is the 2509 loopback address)
Similarly, if you want to log on to the Cisco device that is connected to tty2 (braid 2), You need to log on to Terminal Server 2509:
Telnet X. X 2002
If you want to log on to the Cisco device that is connected to tty65 (AUX), you must log on to the 2509 Terminal Server:
Telnet X. X 2065
That is to say:
For which port to use reverse telnet, You need:
Telnet X. X 2000 + Line)
For Line number query, you can use:
Show Line
Note:
Be sure to configure it on Line using reverse Telnet:
Line tty X
No exec
Transport input all
Otherwise, the port cannot be opened.
Of course, you also need to configure your own privileged mode password and remote connection password on other routers.
