Secure Sockets Layer protocol

Secure sockets layer (SSL) protocol provides secure access to a fabric through Web-based
management tools like Web Tools. SSL support is a standard Fabric OS feature.
Switches configured for SSL grant access to management tools through hypertext transfer protocol
over SSL links (which begin with https://) instead of standard links (which begin with http://).
SSL uses public key infrastructure (PKI) encryption to protect data transferred over SSL
connections. PKI is based on digital certificates obtained from an Internet Certificate Authority (CA)
that acts as the trusted key agent.
Certificates are based on the switch IP address or fully qualified domain name (FQDN), depending
on the issuing CA. If you change a switch IP address or FQDN after activating an associated
certificate, you may have to obtain and install a new certificate. Check with the CA to verify this
possibility, and plan these types of changes accordingly.

Browser and Java support

Fabric OS supports the following Web browsers for SSL connections:
•Internet Explorer v7.0 (Microsoft Windows)
•Mozilla Firefox v2.0 (Solaris and Red Hat Linux)
NOTE
Review the release notes for the latest information and to verify if your platform and browser are
supported.
In countries that allow the use of 128-bit encryption, you should use the latest version of your
browser. For example, Internet Explorer 7.0 and later supports 128-bit encryption by default. You
can display the encryption support (called “cipher strength”) using the Internet Explorer Help:About
menu option. If you are running an earlier version of Internet Explorer, you may be able to download
an encryption patch from the Microsoft Web site at http://www.microsoft.com.
You should upgrade to the Java 1.6.0 Plug-in on your management workstation. To find the Java
version that is currently running, open the Java console and look at the first line of the window.
For more details on levels of browser and Java support, see the Web Tools Administrator’s Guide.
