Parameters
These parameters are displayed:
◆ Host-Key Type – The key type used to generate the host key pair (i.e., public
and private keys). (Range: RSA (Version 1), DSA (Version 2), Both; Default: Both)
The SSH server uses RSA or DSA for key exchange when the client first
establishes a connection with the switch, and then negotiates with the client to
select either DES (56-bit) or 3DES (168-bit) for data encryption.
Note: The switch uses only RSA Version 1 for SSHv1.5 clients and DSA Version 2 for
SSHv2 clients.
