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.
