Usage Information
If you enable this command, clients can log in without a password prompt. This command provides two
levels of authentication:

• checking client host-keys is done with the le specied in the ip ssh pub-key-file command.
NOTE: Administrators must specify the two les (rhosts and pub-key-file) to congure
host-based authentication.
