Switch SSH and User Password Authentication . This option is a subset
of the client public-key authentication shown in figure 8-1. It occurs if the
switch has SSH enabled but does not have login access (login public-key)
configured to authenticate the client's key. As in figure 8-1, the switch authen-
ticates 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.
