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/
