8.2.4.4.7.2. RX Status

8.2.4.4.7.2.1. Lane Error Counters

Statistics about errors detected at the physical coding sub-layer on the data received on a specified physical lane.

Corresponding low-level API class: PP_RXLANEERRORS

# RX Status - Lane Error Counters
resp = await port.pcs_pma.lanes[0].rx_status.errors.get()
resp.alignment_error_count
resp.corrected_fec_error_count
resp.header_error_count

8.2.4.4.7.2.2. Lock Status

Whether the receiver has achieved header lock and alignment lock on the data received on a specified physical lane.

Corresponding low-level API class: PP_RXLANELOCK

# RX Status - Lock Status
resp = await port.pcs_pma.lanes[0].rx_status.lock.get()
resp.align_lock
resp.header_lock

8.2.4.4.7.2.3. Lane Status

The virtual lane index and actual skew for data received on a specified physical lane. This is only meaningful when the lane is in header lock and alignment lock.

Corresponding low-level API class: PP_RXLANESTATUS

# RX Status - Lane Status
resp = await port.pcs_pma.lanes[0].rx_status.status.get()
resp.skew
resp.virtual_lane

8.2.4.4.7.2.4. Clear Counters

Clear all the PCS/PMA receiver statistics for a port.

Corresponding low-level API class: PP_RXCLEAR

# RX Status - Clear Counters
await port.pcs_pma.rx.clear.set()

8.2.4.4.7.2.5. RX FEC Stats

Provides statistics on how many FEC blocks have been seen with a given number of symbol errors.

Corresponding low-level API class: PP_RXFECSTATS

# RX Status - RX FEC Stats
resp = await port.pcs_pma.rx.fec_status.get()
resp.stats_type
resp.data_count # number of values in stats
resp.stats # list of long integers, array of length value_count. The stats array shows how many FEC blocks have been seen with [0, 1, 2, 3....15, >15] symbol errors and the last one is the sum of FEC blocks with <=n symbol errors

8.2.4.4.7.2.6. RX Total Stats

Provides FEC Total counters.

Corresponding low-level API class: PP_RXTOTALSTATS

# RX Status - RX Total Stats
resp = await port.pcs_pma.rx.total_status.get()
resp.total_corrected_codeword_count
resp.total_corrected_symbol_count
resp.total_rx_bit_count
resp.total_rx_codeword_count
resp.total_uncorrectable_codeword_count
post_fec_ber = 1/resp.total_post_fec_ber
pre_fec_ber = 1/resp.total_pre_fec_ber
