I use an SSH proxy server to connect to my switches, and we are required to rotate keys often. With my HP switches, I can use my current public key to copy up an authorized_keys file that has the new key in it. But with IOS 15.2, I don't see any way to handle this non-interactively. I can create a user that has the public key attached to it, but how do I push out a new pubkey to a bunch of 3750's without logging into each of them and manually configuring the admin user?
