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.
