Overview:
Backing up device configurations is good practice and can save a lot of downtime should a device need to be upgraded or swapped out.
Study Notes:
There are multiple ways to backup and restore configurations. TFTP and FTP are covered below.
Use a TFTP server to backup a router configuration
- Start the TFTP server on your PC
- Connect your PC to the router being backed up
- Configure your PC in the same subnet as your router
- Ping the router from your PC to verify IP connectivity
- Console into the router
- Copy the running configuration file from the router to the TFTP server
Router# Router#copy running-config tftp: Address or name of remote host []? 172.16.10.2 Destination filename [Router-confg]? Writing running-config....!! [OK - 497 bytes] 497 bytes copied in 3.011 secs (165 bytes/sec) Router#
Use a TFTP server to restore a router configuration
- Start the TFTP server on your PC
- Connect your PC to the router being backed up via a network cable
- Configure your PC in the same subnet as your router
- Ping the router from your PC to verify IP connectivity
- Console into the router
- Copy the running configuration file from the TFTP server to the router
Router#copy tftp run Address or name of remote host []? 172.16.10.2 Source filename []? Router-confg Destination filename [running-config]? Accessing tftp://172.16.10.2/Router-confg... Loading Router-confg from 172.16.10.2: ! [OK - 497 bytes] 497 bytes copied in 0.01 secs (49700 bytes/sec) Router# %SYS-5-CONFIG_I: Configured from console by console
Use an FTP server to backup a configuration
- Start the FTP server on your PC
- Connect your PC to the router being backed up
- Configure your PC in the same subnet as your router
- Ping the router from your PC to verify IP connectivity
- Console into the router
- Configure the FTP username and password on the router
- Copy the running configuration file from the router to the FTP server
