Backup and restore cisco

1. Connecting to a Cisco Router Using Console

Step 1: Attach a console cable to the console port (Rj-45) located at the back of the router.

Step 2: Open a new HyperTerminal instance from Start-All Programs-Accessories-Communications-HyperTerminal, enter a random name to this connection and choose the com port to use for connecting to the router. Adjust the following port settings to the com port:

Bits per second: 9600

Data bits: 8

Parity: none

Stop bits: 1

Flow control: Hardware

Step 3: After pressing [Enter] a few times you will see the Router> prompt. Go to menu view-font of the hyperterminal and select courier font with font size 14.

Write enable to enter into privileged mode (after issuing the correct enable secret). Here are the steps:

[Router name]>

[Router name]>enable

Password: ..........

[Router name]#

2. Connecting to a Cisco Router Using Telnet

Note that in order to be able to telnet onto a router, a telnet password must have been configured on the router and also telnet access should not be disabled on the specific router.

Before installing a new router you must provide a password for the telnet access on the router, otherwise you will not be able to telnet to it.

Use the console to connect to the router:

[Router name] enable

Password: ..........[insert enable secret here]

[Router name]# sh run

Press [enter] until you see a sentence like: line vty 0 4 (see the example below). Below this sentence you should see a password. If not then you should provide a password. If a password is set but no exec line is seen like in the example below, then telnet is blocked and you should unblock it.

Example:

Line vty 0 4

Password surpass

No exec

a. To Provide a telnet Password

Router#config t

Router(Config)#line vty 0 4

Router(Config)#login

Router(Config)#password [password name]

Press [Ctrl][z] and issue sh run to ensure that password has been set

b. To Unblock telnet Access on Router

Router#config t

Router(Config)#line vty 0 4

Router(Config)#exec

C:\>telnet 10.176.100.2

Password: ..........

[Router name]>enable

Password: ..........

[Router name]#

3. Backup setting routing with ftp/tftp server

[router name]#show run

[router name]#copy run tftp -- to copy the running configuration to TFTP server

[router name]#copy run ftp  --> -- to copy the configuration file from FTP server to the running configuration of the router

4. Restore

[router name]# show run

[router name]#copy ftp run  --> -- to copy the configuration file from FTP server to the running configuration of the router

[router name]#copy tftp run  --> -- to copy the configuration file from TFTP server to the running configuration of the router

[router name]#show run

[router name]#copy run start --> to copy the configuration from running configuration (DRAM) to Startup configuration (NVRAM).
