Description: Cisco UCS equipment:PfcMmuCap:fcoeJumboNodrop managed object property
What is cucsEquipmentPfcMmuCapFcoeJumboNodrop?
This CucsEquipmentMmuPercent value is the share of MMU buffer reserved specifically for no-drop FCoE traffic when jumbo frames (larger FC payload MTU) are in use. It matters because jumbo frames consume more buffer per packet, so if this percentage is undersized relative to the actual jumbo FCoE load, bursts can overrun the no-drop queue and cause drops even though PFC pausing is correctly configured. A value of 25 percent for jumbo mode versus a smaller normal-frame figure would show the extra headroom the ASIC allocates specifically for larger FC frames.
