◆
The SSH server supports up to eight 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.

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.
