Troubleshooting
Problem
When the Chassis Management Module (CMM) is configured with a chassis security policy setting of Secure, Mozilla Firefox versions ESR 17 and ESR 24 are not able to connect to the management module. This limitation is due to these earlier browser levels using outdated Secure Sockets Layer (SSL) protocols, which have been determined not to be secure. The CMM security team has updated the CMM firmware to allow it to interact only with a browser level using the later, secure SSL versions.
