Syntax: aaa authentication ssh login public-key none
Allows SSH client access only if the switch detects a match
between the client's public key and an entry in the client-
public-key file most recently copied into the switch.
To enable client public-key authentication to block SSH clients whose public
keys are not in the client-public-key file copied into the switch, you must
configure the Login Secondary as none. Otherwise, the switch allows such
clients to attempt access using the switch's Operator password.
