Output The port error counter data is displayed as a table that includes the
following properties.
◆ 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 Errs — The number of frame CRC errors detected by the
port.
◆ Dlim 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.
