The Console PortĪny time you have to reset a router's password, or you face an instance where the router can no longer be connected to the network and thus is inaccessible through Telnet, you can use the console port. Later on, we will transition permanently from the insecure Telnet connection method to a server-supplied Secure Shell (SSH) connection as a short exercise in securing router communications when upgrades are not possible. #Cisco hyperterm config how toThe first connection method we will cover is how to connect via a serial console cable connection in HyperTerminal, followed by a Telnet connection into VTY interfaces. Choose Transfer| Capture Text to select a file to capture the data from, and Transfer | Capture | Stop to stop the transfer. This will eliminate automatic pausing while you record your running configuration within your HyperTerminal session. Router# copy running-config startup-config In global configuration mode, enter the following: But if you leave the screen page to 24 lines, you will have to remove the – more-line from your recorded text (it's very annoying when it's in there). HyperTerminal is especially good at recording and uploading the running configuration from and to routers. Although you can use HyperTerminal through the console and auxiliary ports, each has a special purpose, and a need for safeguarding. It's a hoot, and it works with little fuss. In fact, I still have a legacy Apple IIc running ProTERM in my garage lab, and I use it to configure intelligent switches and routers, just for fun. It turns out that anything that can watch the status of a serial port and pass information to and from data buffers to the screen can be a functional terminal program and can work on a router to configure it through its asynchronous connections. I go back to the old days of telecommunications where terminal programs such as Telix and MacTerm were all the rage for connecting to bulletin board systems (BBSs), which are yesterday's equivalent of forums and chat. First we will discuss using HyperTerminal asynchronously and then we'll discuss the finer points of using it in network communications as a substitute for Telnet. If you have access to HyperTerminal, you are in luck as you can use it in two major ways for connecting to Cisco routers: asynchronously through the console (CONS) or auxiliary (AUX) port, and as a Telnet application. #Cisco hyperterm config PcIf you have used a PC since 1995 and it ran something newer than Windows 3.1, there is a good chance you have heard of or maybe even used HyperTerminal to perform the functions of communication and terminal emulation.
