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).
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_rx_c3_timeout
The number of receive class 3 frames received at this port and discarded at the
transmission port due to timeout (platform-and port-specific).
er_tx_c3_timeout
The number of transmit class 3 frames discarded at the transmission port due to
timeout (platform- and port-specific).
er_c3_dest_unreach
The number of class 3 frames discarded because the transmit port, although it is
determined, cannot send the frame at the moment when the error occurs.
er_other_discard
The number of other discarded due to route lookup failures or other reasons.
er_zone_discard
The number of class 3 frames discarded due to zone mismatch.
