For the initial configuration of the router using the console port connected to a console or rollover cable and RJ-45 to DB-9 COM1 port to connect to the computer. This must have terminal emulation software such as HyperTerminal.
The configuration parameters are:
• The appropriate COM port
• 9600 baud
* 8 data bits
• No parity
• 1 stop bit
• No flow control
When a Catalyst switch or a Cisco router are implemented, there are three fundamental operations to be carried out within the network device:
Step 1
The device locates the hardware and performs a series of routines for detecting it. A term often used to describe this initial set of routines is power-on-self-test (POST), or evidence of initiation.
Step 2
Once your hardware is displayed in a correct position of operation, the device performs startup routines. These routines initiate the switch or router locating and loading the operating system software.
Step 3
After loading the operating system, the device tries to locate and apply the settings that define the details needed to operate the network. Usually there is a boot sequence of routines that provide alternatives to the start of the software when needed.
A router or a switch can be configured from different locations:
• In the initial installation, the network administrator usually configures the network devices from a console terminal connected through the console port.
• If the administrator needs to support remote devices, a local connection via modem to the auxiliary port of the device allows one to configure the network devices.
• Devices with IP addresses provided may allow Telnet connections to the task of configuration.
• Download a configuration file from a server Trivial File Transfer Protocol (TFTP).
• Configure the device using a browser Hypertext Transfer Protocol (http).
