User Guidelines
When using the keyword generate, a private key and a public key of the given type
(RSA/DSA) are generated for the SSH client. Downloading a configuration file with
a Key Generating command is not allowed, and such download will fail.
When using the keyword key-pair, the user can import a key-pair created by
another device. In this case, the keys must follow the format specified by RFC
4716.
If the specified key already exists, a warning will be issued before replacing the
existing key with a new key.
Use the no ip ssh-client key command to remove a key pair. Use this command
without specifying a key-type to remove both key pairs.
Ta b l e 2 describes the expected behavior of keys, default and users within the
various operations.
If no keys are included in text-based configuration file, the device generates it’s
own keys during initialization. If the Running Configuration contains default keys
(not user-defined), the same default keys remain.
Examples
Example 1 - In the following example, a key pair of the RSA type is created:
switchxxxxxx(config)# ip ssh-client key rsa generate
The SSH service is generating a private RSA key.
