Wrap-A - The flow of the primary ring is entering through port A (primary in) and is wrapped by the MAC, causing the ring to exit through port A (secondary out). Port B is disconnected from the ring. If the HSIM-F6 MAC Configuration reads “Wrap-A” the ring has lost the redundancy of the secondary ring due to the wrapped condition. This configuration should be repaired, as additional problems could isolate stations from the FDDI ring.
