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 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 RSA host keys before enabling the SSH server.
Example
Console#ip ssh crypto host-key generate
