• 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.
• Save Host-Key from Memory to Flash – Saves the host key from RAM (i.e.,
volatile memory) to flash memory. Otherwise, the host key pair is stored to RAM by
default. Note that you must select this item prior to generating the host-key pair.
(Default: Disabled)
