5 Configuration D-Link Web Smart Switch User Manual This page allows you to configure the SSL global state and the Ciphersuite settings. Select Enable or Disable and then click Apply to change the SSL state or the Ciphersuite settings of the Switch. By default, SSL is Disabled and all Ciphersuites are Enabled.

After saving configuration, please wait around 10 seconds for the system summery page. Security > SSH > SSH Settings SSH is an abbreviation of Secure Shell, which is a program allowing secure remote login and secure network services over an insecure network. It allows a secure login to remote host computers, a safe method of executing commands on a remote end node, and will provide secure encrypted and authenticated communication between two non-trusted hosts. SSH, with its array of unmatched security features is an essential tool in today's networking environment. It is a powerful guardian against numerous existing security hazards that now threaten network communications.

The default is Disabled. Max Session (1 - 4): Enter a value between 1 and 4 to set the number of users that may simultaneously access the Switch. The default setting is 4. Connection Timeout (120 - 600): Allows the user to set the connection timeout. The use may set a time between 120 and 600 seconds. The default setting is 120 seconds. Authfail Attempts (2 - 20): Allows the Administrator to set the maximum number of attempts that a user may try to log on to the SSH Server utilizing the SSH authentication. After the maximum number of attempts has been exceeded, the Switch will be disconnected and the user must reconnect to the Switch to attempt another login. The number of maximum attempts may be set between 2 and 20. The default setting is 2.
