◆

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.

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.
