The page includes the following fields:
Object Description
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.
Public-Key of Host-Key
-DSA (Version 2): The first field indicates that the encryption method used by
SSH is based on the Digital Signature Standard (DSS). The
last string is the encoded modulus.
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: RSA
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.
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.
Generate This button is used to generate the host key pair. Note that you must first
generate the host key pair before you can enable the SSH server on the SSH
Server Settings page.
Clear This button clears the host key from both volatile memory (RAM) and non-volatile
memory (Flash).
The Managed Switch uses only RSA Version 1 for SSHv1.5 clients and DSA Version 2 for
SSHv2 clients.
