Port The port number.
Prim Seq Err The number of state machine protocol errors detected
by the port hardware.
Disc Frms The number of received frames discarded due to a
frame size of less than size words or to frames
dropped because the BB_Credit was zero. This
number is counted during the first round of frame
verification and applies to both Class 2 and Class 3
traffic.
Inv Tx Wrds The number of 10-bit transmission words that the
port is unable to map to 8-bit bytes because of
disparity errors or misaligned K characters while in
the OL2 or OL3 state.
CRC Errors The number of frame CRC errors detected by the
port.
Delim Errs The number of invalid frame delimiters (SOF or EOF)
received by the port.
Addr Id Errs The number of frames received with unknown
addressing.
FrmsTooShrt The number of frames received that are too short.
