portstatsshow
output shows very high value for the paratmeter "tim_txcrd_z
", which is again a clear indication of the port being over utilized.- The "tim_txcrd_z "(Time TX Credit Zero (2.5Us ticks))parameter in the "portstatshow" command output tells us the number of times, the port was unable to transmit frames because the transmit BB (buffer-to-buffer)credit was zero.
