The server key is a private key that is never shared outside the switch.
The host key is shared with the SSH client, and is fixed at 1024 bits.

The SSH server supports up to four client sessions. The maximum
number of client sessions includes both current Telnet sessions and
SSH sessions.
The SSH server uses DSA or RSA 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.
You must generate DSA and RSA host keys before enabling the SSH
server.
