What is Console Access to Cisco Devices

Share This

Console Access is an important topic for networking student, so in this lesson, I am going to explain console access to Cisco devices. All Cisco router and switches have a console port also known as the management interface. It is used to connect a computer directly to a router or switch and manage the router or switch. The console port is also used for initial configuration.

Normally router console port is an RJ45 port. Rollover cable is used to connect the Serial/COM port of the computer to the router or switch console port. It has to type RJ-45 to DB9 Console access cable and RJ-45 to RJ-45 Console access cable.

The terminal software is also required for accessing the router and switches. The Tera Term, Putty, and Hyper Terminal are usually used to access the router and switches on a console port. Most of the Peoples use Putty software for console access. The figure below shows the terminal window of putty.

The cable is used to connect the serial port of the host and the console port on the device. The majority of computers and notebooks are now manufactured without built-in serial ports.

If the host is using a computer without a serial port then the USB port can be used to establish a console access connection. For this purpose, a USB-to-RS-232 compatible serial port adapter is required when using the USB port.

The Cisco Integrated Service Router G2 supports a USB connection. It should use USB Type-A to USB Type-B cable, as well as an operating system device driver.

The driver for this type of cable is available from www.cisco.com. These routers are using two console ports, only one console port can be active at a time. When someone connects the USB cable into the USB console port, the RJ-45 console port becomes inactive.

If the USB cable is not plugged into the USB port, the RJ-45 port becomes active. In the case of connecting the USB cable, the Type-A side should be connected to the computer side and type-B side should be connected to the router side.
