stat_mc_rx
The number of multicast frames received.
stat_mc_to
The number of multicast timeouts.
stat_mc_tx
The number of multicast frames transmitted.
tim_rdy_pri
The number of times that sending R_RDY or VC_RDY primitive signals was a
higher priority than sending frames, due to diminishing credit reserves in the
transmitter at the other end of the fiber. This parameter is sampled at intervals of
1.8 microseconds, and the counter is incremented by 1 if the condition is true.
tim_txcrd_z
The number of times that the port was unable to transmit frames because the
transmit BB credit was zero. The purpose of this statistic is to detect congestion or
a device affected by latency. This parameter is sampled at intervals of 2.5
microseconds, and the counter is incremented if the condition is true. Each
sample represents 2.5 microseconds of time with zero Tx BB Credit. An increment
of this counter means that the frames could not be sent to the attached device for
2.5 microseconds, indicating degraded performance.
tim_txcrd_z_vc
The number of times that the port was unable to transmit frames because the
transmit BB credit was zero for each of the port's 16 Virtual Channels (VC 0-15).
The purpose of this statistic is to detect congestion or a device affected by latency.
This parameter is sampled at intervals of 2.5 microseconds (microseconds), and
the counter is incremented if the condition is true. Each sample represents 2.5
microseconds of time with zero Tx BB Credit. An increment of this counter means
that the frames could not be send to the attached device for 2.5 microseconds,
indicating degraded performance (platform- and port-specific).
fec_cor_detected
The number of errors corrected by FEC.
fec_uncor_detected
The number of errors left uncorrected by FEC.
er_enc_in
The number of encoding errors inside frames.
er_crc
The number of frames with cyclic redundancy check (CRC) errors.
er_trunc
The number of frames shorter than the minimum frame length.
er_toolong
The number of frames longer than the maximum frame length.
er_bad_eof
The number of frames with bad end-of-frame.
er_enc_out
The number of encoding error outside frames.
er_bad_os
The number of invalid ordered sets (platform- and port-specific).
er_pcs_blk
The number of Physical Coding Sublayer (PCS) block errors. This counter records
encoding violations on 10 Gbps or 16 Gbps ports. This is applicable only on
platforms that support 10 Gbps or 16 Gbps ports.
