SCP2 from one switch to another with Public key authentication

[eyeV]

Hi everybody!

I'd like to copy configuration file (like switch.cfg) from one switch to another directly by SCP2. Can I set public key authentication between swithces? I know how to load public key to switch, but can XOS generate this public key?

I hope you get my idea.

If it impossible, can you suggest me another way to do it (TFTP or something) please?

You can use SCP2 to transfer files between switches. You just need to "enable ssh2" on the CLI and a key will be created. Are you trying to do this without a password login?

Switch# scp2 flowtrack.py johndoe@192.0.2.100:flowtrack.py
Upload /config/flowtrack.py to
Keyboard-interactive authentication
Enter password for johndoe:
Connected to 192.0.2.100.

Some backgound about it. I have some switches in production network and one switch in cold reserve. My idea is automaticaly copy all .cfg files from switches to reserve switch to minimize recovery time in case of replacement equipment.

Yes, it works perfectly. But I'd like to do it without keyboard-interactive authentication. I'm going to execute this command remotely by cron.
