Cisco router installation and maintenance steps and commands (1)

A router is a commonly used network device. How do we install a router for beginners? How can I maintain a fault? The following article will give you a detailed answer.

Installation steps:

Step 1: control port connection

First, connect one end of the control cable RJ45 in the CISCO2500/1000 series router accessories to the cisco console port, CISO7000/4000 Series routers connect one end of the DB25 of the MODEM cable to the cisco console port, and one end of DB9 to the COM1/2 of the PC.

Set the simulation TERMINAL program on the PC: for example, use the TERMINAL program in WINDOWS, use COM1/2, 9600BPS, 8 data bit, 2 stop bit. Others use the default value. After the control port is connected, turn on the power switch of the router.

Step 2: initial installation

Generally, it is recommended that you use a machine for installation, which is both beautiful and easy to maintain.

Note: The vro must use a valid power supply. Generally, the zero-ground voltage of the power supply is less than 4 V, and the zero-fire/ground-fire voltage is 220 V. Ground Wire Protection basically requires that the devices connected to the internet have a ground wire. These devices include hosts, workstations, hubs, switches, routers, and MODEM connected To routers. The terminal or PC that configures the router must also use a valid power supply.

CISCO synchronous serial interfaces are commonly used. Different interfaces, such as RS232 and V.35, can be obtained through different cables. In addition, the cables of CISCO synchronous serial interface cables are specially pre-fabricated.

During the first installation, the system automatically enters dialog setup. Answer the following questions in sequence: vro name, encrypted super logon password, super logon password, remote logon password, dynamic routing protocol, and interface configuration. Then, answer YES to save the configuration. Wait for 2 minutes and press Enter. The vro name is displayed. Run the ENABLE command to obtain the super logon password. The vro name # is displayed #. Enter config terminal to configure the vro:

NO SERVICE CONFIG

No ip domain-LOOKUP

Further configuration)

Exit by CTRL-Z and the vro name # appears #. Enter write memory to save the configuration.

Step 3: Configure synchronous dialing, leased line, and DDN connections
