Device encounters a corrupt control symbol

6A. ACTION: Moves from the port OK state to the input error-stopped state

6B. ACTION: Sends a packet-not-accepted control symbol to the sending device

6C. ACTION: Device silently discards all packets until a restart-from-error (link-request/input-status)

control symbol is encountered

6D: ACTION: Moves from the input error-stopped state to the port OK state

Device detects protocol violations

7A. DETAIL: Any acknowledge control symbol with an unexpected ackID value

7B. DETAIL: Unsolicited acknowledge control symbol

7C. DETAIL: Received packet-accepted control symbol before packet transmission has completed

7D. DETAIL: Received link-request control symbol before sending link-response control symbol for

previous link-response/input-status control symbol

7E. DETAIL: Unexpected link-response control symbol

7F. DETAIL: Unexpected restart-from-retry control symbol

7G. DETAIL: Unexpected training pattern

7H. DETAIL: Unexpected stomp control symbol

7I. DETAIL: Unexpected EOP control symbol

Device encounters a protocol violation.

8A. ACTION: Moves from the port OK state to the output error-stopped state.

8B.ACTION: Device stops transmitting new packets

8C. ACTION: Device sends link-request/input-status (restart-from-error) control symbol if no

link-request control symbol is already outstanding (must wait for previous one to complete) and

waits for link-response control symbol

8D. ACTION: Moves from the output error-stopped state to the port OK state

8E. ACTION: Starts re-transmitting at the ackID value returned with the received link-response

control symbol

Device encounters a packet-not-accepted control symbol

9A. ACTION: Moves from the port OK state to the output error-stopped state

9B.ACTION: Device stops transmitting new packets

9C. ACTION: Device sends link-request/input-status (restart-from-error) control symbol if no

link-request control symbol is already outstanding (must wait for previous one to complete) and

waits for link-response control symbol

9D. ACTION: Moves from the output error-stopped state to the port OK state

9E. ACTION: Starts re-transmitting at the ackID value returned with the received link-response

control symbol
