Security > SSL
Secure Sockets Layer (SSL) is a security feature that provides a secure communication path between a Web
Management host and the Switch Web UI by using authentication, digital signatures and encryption. These
security functions are implemented by Ciphersuite, a security string that determines the cryptographic
parameters, encryption algorithms and key sizes to be used for an authentication session and consists of
three levels: key exchange, encryption and has algorithm.
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
.

When SSL is enabled, it will take longer time to open
a web page due to encryption and HTTP will be disabled.
