It is an open-source SSH and Telnet client that was originally developed putty for Windows before being ported to macOS. The client enables users to connect to a computer remotely and securely transfer files.

 

Although Putty is not supported on all sorts of routers, it does have support for Cisco routers and switches.
The major advantage of Putty is that it has a lot of features including the ability to do basic functions like copy/paste.


A terminal emulator is a program that offers a terminal-based interface to communicate with another computer. A good example of this is the PuTTY Terminal Emulator program.


Putty Terminal Emulator is an open-source, cross-platform tool that can be used to emulate a terminal on another computer. It provides the user with full control over a device’s console and supports extensions such as XTERM and TN3270 for different types of sessions.

3)A console cable for connecting the router to the PC.

Some router console ports join at once to the RJ-forty five connector at the rollover cable, wherein case you won’t want an adapter. However, a few routers use a nine-pin or 25-pin console connection. In this situation, you’ll want both an RJ-forty five to DB-nine or RJ-forty five to a DB-25 adapter. The RJ-forty five cable connector plugs into the adapter and the adapter plugs into the router’s console port. Check the router’s guide or online assist documentation to make certain you supply the best adapter.


4)HyperTerminal software, is available by default in Windows XP operating system.


HyperTerminal also can permit IT to take serial-port to manipulate outside gadgets or structures including medical instruments, robots, or radio communications stations. IT specialists also can use HyperTerminal to troubleshoot any troubles while putting in place the usage of a modem.

Cable choice is an elaborate system due to the fact the cables aren't all well suited to the ports. In order to resolve this problem, Putty Emulator is a utility that may emulate one-of-a-kind cable kinds and their respective ports.


6)In the absence of a Serial port one can make use of a USB port present on the system.


In computing, a serial port is a serial verbal exchange interface that records transfers in or out sequentially one bit at a time. This is in assessment to a parallel port, which communicates more than one bit concurrently in parallel. Throughout maximum of the records of private computer systems, records have been transferred thru serial ports to gadgets along with modems, terminals, and numerous peripherals, and without delay among computer systems.


Server computer systems can also additionally use a serial port as a managed console for diagnostics, at the same time as networking hardware (along with routers and switches) generally use serial console ports for configuration, diagnostics, and emergency renovation access. To interface with those and different gadgets, USB-to-serial converters can speedy and without difficulty upload a serial port to a contemporary-day PC.


Connecting router or switch to computer:


1)Connect one of the ends of the console cable to the console port of the router.


2)Connect other ends of the cable to a serial port of the Computer.

 

3)In absence of a serial port use RJ-45 to the USB console port and connect to the USB port available on Computer.


Configuring Cisco router or switch:


1. Make the necessary configurations that are needed.

Configuration control is an essential device for dealing with complicated software program systems. Lack of configuration control can purpose severe issues with reliability, uptime, and the capacity to scale a system.
