CLI – This example enables SSH, sets the authentication parameters, and displays
the current configuration. It shows that the administrator has made a connection via
SHH, and then disables this connection.
Generating the Host Key Pair
A host public/private key pair is used to provide secure communications between an
SSH client and the switch. After generating this key pair, you must provide the host
public key to SSH clients and import the client’s public key to the switch as
described in the section “Importing User Public Keys” on page 3-79.
Field Attributes
• Public-Key of Host-Key – The public key for the host.
- RSA (Version 1): The first field indicates the size of the host key (e.g., 1024), the
second field is the encoded public exponent (e.g., 65537), and the last string is
the encoded modulus.
