When accessing the server again, the client will use thesaved server host public key to authenticate the server.• Without first-time authentication, a client not configured with the server host public key willdeny to access the server. To access the server, a user must configure in advance the serverhost public key locally and specify the public key name for authentication.Enable the device to support first-time authenticationFollow these steps to enable the switch to support first-time authentication:To do...
