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.
