Explore how to back up a cisco router configuration file

Vro is a commonly used network device. I believe everyone knows the importance of backing up the cisco router configuration file. Next we will introduce how to use the COPY command to back up the cisco router configuration file, and how to COPY and back up the cisco router configuration file backup from the TFTP server.

1. copy running-config startup-config. This Command copies the correct configurations stored in RAM to the nvram of the vro. In this way, the router will use this correct configuration during the next startup.

2. copy running-config tftp. This Command copies the correct configuration file in RAM to the TFTP server. We strongly recommend that the network administrator do this, if the router cannot load the configuration file normally from NVRAM, we can copy the correct configuration file from TFTP.

It168 # copy running-config tftp

Address or name of remote host

[]? 129.0.0.3

Destination file name [it168-confg]?

After the network administrator enters the command and press enter, the vro requires that the IP address of the TFTP server be entered. After the Server IP address is correctly entered, the vro also requires the network administrator to provide the name of the configuration file for backing up the cisco router. Generally, we recommend that you use a file name that is easily remembered by the Administrator. At this time, the router will prompt the Administrator to press YES to confirm the operation.

3. copy tftp running-config. If there is a problem with the vro configuration file, we can copy the backup cisco vro configuration file from the TFTP server. The specific configuration is as follows:

Copy tftp running-config

Address or name of remote host []?

129.0.0.3

Source filename []? It168-confg

Destination file name [running-config]?

Accessing tftp: // 129.0.0.3/it168-confg

Loading it168-confg from 129.0.0.3
