Ciphersuite
This screen will allow the user to enable SSL on the Switch and implement any one or combination of listed ciphersuites
on the Switch. A ciphersuite is a security string that determines the exact cryptographic parameters, specific encryption
algorithms and key sizes to be used for an authentication session. The Switch possesses four possible ciphersuites for the
SSL function, which are all enabled by default. To utilize a particular ciphersuite, disable the unwanted ciphersuites,
leaving the desired one for authentication.
When the SSL function has been enabled, the web will become disabled. To manage the Switch through the web based
management while utilizing the SSL function, the web browser must support SSL encryption and the header of the URL
must begin with https://. (Ex. https://10.90.90.90) Any other method will result in an error and no access can be authorized
for the web-based management.
