Command Usage
◆ 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.
