public key for authenticating

[WILLIAM STEGMAN]

is there a way to use public key authentication in addition to user based authentication in IOS similar to the authentication feature available in Linux where you can create a pair, copy the public key to the remote server and use your private key to authenticate?

thank you,

Bill

You can achive through this RADIUS and TACACS server for authentiaction.

Remote Authentication Dial-In User Service (RADIUS)

TACACS.

I see, so instead of putting a public key on the router, put a certificate on the radius server and the client wanting to connect. EAP/TLS

thank you
