Use the COPY command to back up the cisco router configuration file

The COPY command is often used during vro configuration. Next we will introduce how to use the COPY command to back up the configuration file, and how to COPY the backup configuration file from the TFTP server.

Figure 1

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 because 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]? !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! 624 bytes copied in 7.05 secs it168#

After the network administrator enters the command and press enter, the router requires that the IP address of the TFTP server be entered. After the Server IP address is correctly entered, the router also requires the network administrator to provide the configuration file name to be backed up. 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 configuration file from the TFTP server. The specific configuration is as follows:

it168#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 (via fastethernet 0/0): !!!!!!!!!!!!!!!!!!!!!!! [ok-624 bytes] 624 bytes copied in 9.45 secs it168#
