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

chassis.
