RX Statistics

Clear Counter

Clear all the receive statistics for a port. The byte and packet counts will restart at zero.

Corresponding CLI command: PR_CLEAR

# RX Statistics - Clear Counter
await port.statistics.rx.clear.set()

Calibrate

Calibrate the latency calculation for packets received on a port. The lowest detected latency value (across all Test Payload IDs) will be set as the new base.

Corresponding CLI command: PR_CALIBRATE

# RX Statistics - Calibrate
await port.statistics.rx.calibrate.set()

Total Counter

Obtains statistics concerning all the packets received on a port.

Corresponding CLI command: PR_TOTAL

# RX Statistics - Total Counter
resp = await port.statistics.rx.total.get()
resp.byte_count_since_cleared
resp.packet_count_since_cleared
resp.bit_count_last_sec
resp.packet_count_last_sec

Non-TPLD Counter

Obtains statistics concerning the packets without a test payload received on a port.

Corresponding CLI command: PR_NOTPLD

# RX Statistics - Non-TPLD Counter
resp = await port.statistics.rx.no_tpld.get()
resp.byte_count_since_cleared
resp.packet_count_since_cleared
resp.bit_count_last_sec
resp.packet_count_last_sec

PFC Counter

Obtains statistics of received Priority Flow Control (PFC) packets on a port.

Corresponding CLI command: PR_PFCSTATS

# RX Statistics - PFC Counter
resp = await port.statistics.rx.pfc_stats.get()
resp.packet_count
resp.quanta_pri_0
resp.quanta_pri_1
resp.quanta_pri_2
resp.quanta_pri_3
resp.quanta_pri_4
resp.quanta_pri_5
resp.quanta_pri_6
resp.quanta_pri_7

Extra Counter

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

Corresponding CLI command: 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

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 CLI command: PR_TPLDS

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

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 CLI command: 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

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 CLI command: PR_TPLDLATENCY

# RX Statistics - TPLD - Latency Counter
resp = await port.statistics.rx.access_tpld(tpld_id=0).latency.get()
resp.avg_last_sec
resp.max_last_sec
resp.min_last_sec
resp.avg_val
resp.max_val
resp.min_val

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 CLI command: PR_TPLDJITTER

# RX Statistics - TPLD - Jitter Counter
resp = await port.statistics.rx.access_tpld(tpld_id=0).jitter.get()
resp.avg_last_sec
resp.max_last_sec
resp.min_last_sec
resp.avg_val
resp.max_val
resp.min_val

TPLD - Traffic Counter

Obtains traffic statistics concerning the packets with a particular test payload identifier received on a port.

Corresponding CLI command: PR_TPLDTRAFFIC

# RX Statistics - TPLD - Traffic Counter
resp = await port.statistics.rx.access_tpld(tpld_id=0).traffic.get()
resp.byte_count_since_cleared
resp.packet_count_since_cleared
resp.bit_count_last_sec
resp.packet_count_last_sec

Filter Statistics

Obtains statistics concerning the packets satisfying the condition of a particular filter for a port.

Corresponding CLI command: PR_FILTER

# RX Statistics - Filter Statistics
resp = await port.statistics.rx.obtain_filter_statistics(filter=0).get()
resp.byte_count_since_cleared
