pre-6.1.1.0 Introduced on the E-Series.
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/
