A port can become diagnostically disabled (D-Disable) when DOT1S experiences a severe
error condition. The most common cause is when the DOT1S software experiences BPDU
flooding. The flooding criteria is such that DOT1S receives more than 15 BPDUs in a
3-second interval. The other causes for DOT1S D-Disable are extremely rare.
