and implementation of the certificate file and can be downloaded to the Switch by utilizing a TFTP server. The Switch
supports SSLv3 and TLSv1. Other versions of SSL may not be compatible with this Switch and may cause problems
upon authentication and transfer of messages from client to host.

Download Certificate

This window is used to download a certificate file for the SSL function on the Switch from a TFTP server. The
certificate file is a data record used for authenticating devices on the network. It contains information on the owner,
keys for authentication and digital signatures. Both the server and the client must have consistent certificate files for
optimal use of the SSL function. The Switch only supports certificate files with .der file extensions. The Switch is
shipped with a certificate pre-loaded though the user may need to download more, depending on user circumstances.

Ciphersuite

This window 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.

Description
Enable or Disable the SSL status on the switch. The default is disabled.
This field will set the time between a new key exchange between a client and a host using
the SSL function. A new SSL session is established every time the client and host go
through a key exchange. Specifying a longer timeout will allow the SSL session to reuse the
master key on future connections with that particular host, therefore speeding up the
negotiation process. The default setting is 600 seconds.
