Sample configuration: periodic upload of router configuration
Pete Vickers sent me a very interesting configuration sample:
To get an IOS device to upload it’s configuration periodically to an external FTP server:
ip ftp source-interface loopback 0
ip ftp username ftp_username
ip ftp password ftp_password
file prompt quiet
!
kron policy-list backup
cli copy running-config ftp://10.20.30.40
!
kron occurrence daily-backup at 0:30 recurring
policy-list backup
The beauty of this example is that you can use it on platforms that don't support Embedded Event Manager (which has a very similar cron functionality) as the kron commands were introduced in 12.2T and 12.3 IOS releases.
Note: You have to use the file prompt quiet configuration command as the commands executed by kron cannot supply any user input
router(config)#archive
! configure config archival
router(config-archive)#path scp://user:password@host/
! where to archive
router(config-archive)#write-memory
! archive every "write mem"
router(config-archive)#time-period 1440
! also archive daily
e.g. I've got
"scp -q administrator@$ROUTER:running-config $CONFIGFILE"
and on my linux box I've generated a public/private key pair, and I'm wanting to put the public key onto the router...
I know I could save from the router to a server as per this blog post, but I want to have the server make the request as I have it doing it for other devices and it makes sense to have it all in one place.
do show run | redirect tftp://192.168.0.43/router.txt
as the kron policy? Then you don't need additional commands to copy the config. I'm putting these on all my routers, naming the file after the router, so I have a central repository of backups that get automatically replaced once a week.
