• 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.
