Storing Last and Bad PDUs
Dell Networking OS stores the last notification sent/received and the last bad protocol data unit (PDU)
received on a per peer basis. The last bad PDU is the one that causes a notification to be issued.
In the following example, the last seven lines shown in bold are the last PDUs.
