Note

SSH in the ProCurve Series 2500 switches is based on the OpenSSH software toolkit. For more information

Switch SSH and User Password Authentication . This option is a subset of the client public-key authentication show in figure 26. It occurs if the switch has SSH enabled but does not have login access (login rsa) configured to authenticate the client’s key. As in figure 26, the switch authenticates itself to SSH clients. Users on SSH clients then authenticate themselves to the switch (login and/or enable levels) by providing passwords stored locally on the switch or on a TACACS+ or RADIUS server. However, the client does not use a key to authenticate itself to the switch.
