Session-aware Load Balancing (SLBC) (5.6.1)
New SLBC features added to FortiOS 5.6.1.
FortiController-5000 series independent port splitting (42333)
FortiOS 5.6.1 supports splitting some 40G FortiController front panel fiber channel front panel interfaces in to 10G ports. In previous versions of FortiOS this configuration was not supported and all FortiController fiber channel front panel interfaces had to operate at the same speed.
