VIAVI TestCenter : Does the DX and DX2 modules support PFC counters and measurements?
DX and DX2 and DX3 Modules:
• Does not support PFC counters nor can it measure the Pause response time.
• It will process PFC frames but the entire port will pause.
• Basially it only supports 1 priority queue (if a PFC pause is received that matches one of the priorities, all streams on the port will pause)
• For multi speed modules each port speed will have this behavior.
