8.2.4.3.15.2.6. Extra Counter

Obtains statistics concerning special errors received on a port since received statistics were cleared.

Corresponding low-level API class: PR_EXTRA

# RX Statistics - Extra Counter
resp = await port.statistics.rx.extra.get()
resp.fcs_error_count
resp.pause_frame_count
resp.gap_count
resp.gap_duration
resp.pause_frame_count
resp.rx_arp_reply_count
resp.rx_arp_request_count
resp.rx_ping_reply_count
resp.rx_ping_request_count

8.2.4.3.15.2.7. Received TPLDs

Obtain the set of test payload IDs observed among the received packets since receive statistics were cleared. Traffic statistics for these test payload streams will have non-zero byte and packet count.

Corresponding low-level API class: PR_TPLDS

# RX Statistics - Received TPLDs
await port.statistics.rx.obtain_available_tplds()

8.2.4.3.15.2.8. TPLD - Error Counter

Obtains statistics concerning errors in the packets with a particular test payload id received on a port. The error information is derived from analyzing the various fields contained in the embedded test payloads of the received packets, independent of which chassis and port may have originated the packets. Note that packet-lost statistics involve both a transmitting port and a receiving port, and in particular knowing which port originated the packets with a particular test payload identifier. This information requires knowledge of the global test environment, and is not supported at the port-level.

Corresponding low-level API class: PR_TPLDERRORS

# RX Statistics - TPLD - Error Counter
resp = await port.statistics.rx.access_tpld(tpld_id=0).errors.get()
resp.non_incre_payload_packet_count
resp.non_incre_seq_event_count
resp.swapped_seq_misorder_event_count

8.2.4.3.15.2.9. TPLD - Latency Counter

Obtains statistics concerning the latency experienced by the packets with a particular test payload id received on a port. The values are adjusted by the port-level P_LATENCYOFFSET` value. A special value of -1 is returned if latency numbers are not applicable. Latency is only meaningful when the clocks of the transmitter and receiver are synchronized. This requires the two ports to be on the same test module, and it requires knowledge of the global test environment to ensure that packets are in fact routed between these ports.

Corresponding low-level API class: PR_TPLDLATENCY

# RX Statistics - TPLD - Latency Counter
resp = await port.statistics.rx.access_tpld(tpld_id=0).latency.get()

8.2.4.3.15.2.10. TPLD - Jitter Counter

Obtains statistics concerning the jitter experienced by the packets with a particular test payload id received on a port. The values are the difference in packet-to-packet latency, and the minimum will usually be zero.A special value of -1 is returned if jitter numbers are not applicable. They are only available for TID values 0..31.

Corresponding low-level API class: PR_TPLDJITTER

# RX Statistics - TPLD - Jitter Counter
resp = await port.statistics.rx.access_tpld(tpld_id=0).jitter.get()
