Usage
Information This command specifies the file used for the host-based authentication. The
creates/ file overwrites the flash://ADMIN_DIR/ssh/knownhosts file and
deletes the user-specified file. Even though this command is a global configuration
command, it does not appear in the running configuration because you only need
to run this command once.
The file contains the OpenSSH-compatible public keys of the host for which host-
based authentication is allowed. An example known host file format:
poclab4,123.12.1.123 ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAIEAox/

NOTE: For rhostfile and pub-key-file, the administrator must FTP the
file to the chassis.
Example Dell#conf
Dell(conf)# ip ssh pub-key-file flash://knownhosts
