Back up and Restore Configuration Files (Router)

Use a TFTP Server to Backup and Restore a Configuration

This is a step−by−step approach to copy a configuration from a router to a TFTP server, and back to another router. Before you proceed with this method, make sure you have a TFTP server on the network to which you have IP connectivity.

1. At the Router> prompt, issue the enable command, and provide the required password when prompted.

The prompt changes to Router#, which indicates that the router is now in privileged mode.

2. Copy the running configuration file to the TFTP server:

Router#copy running−config tftp:
Address or name of remote host []? 64.104.207.171

Destination filename [Router−confg]? backup_cfg_for_my_router !!

1030 bytes copied in 2.489 secs (395 bytes/sec)

Router#

3.  Open the configuration file with a text editor. Search for and remove any line that starts with "AAA".

Note: This step is to remove any security commands that can lock you out of the router.

4. Copy the configuration file from the TFTP server to a new router in privileged (enable) mode which has a basic configuration.

Router#copy tftp: running−config
Address or name of remote host []? 64.104.207.171

Source filename []? backup_cfg_for_my_router
Destination filename [running−config]?
Accessing tftp://10.66.64.10/backup_cfg_for_my_router...
