H3C端口负载和问题

 Last 300 seconds input:  262 packets/sec 31831 bytes/sec 0%

 Last 300 seconds output:  51 packets/sec 6123 bytes/sec 0%

 Input (total):  694679148 packets, 315833220069 bytes

         244852258 unicasts, 255899789 broadcasts, 193881864 multicasts, 0 pauses

 Input (normal):  694679148 packets, 315833220069 bytes

         244852258 unicasts, 255899789 broadcasts, 193881864 multicasts, 0 pauses

 Input:  45237 input errors, 626 runts, - giants, - throttles

         30448 CRC, - frame, 0 overruns, 14163 aborts

         - ignored, - parity errors

 Output (total): 216737156 packets, 40899811934 bytes

         184448899 unicasts, 1625282 broadcasts, 30662975 multicasts, 0 pauses

 Output (normal): 216737156 packets, 40899811934 bytes

         184448899 unicasts, 1625282 broadcasts, 30662975 multicasts, 0 pauses

 Output: 0 output errors, - underruns, - buffer failures

         0 aborts, 0 deferred, 0 collisions, - late collisions

 Last 300 seconds input:  262 packets/sec 31831 bytes/sec 0% 中的 0%是负载吗，本交换机是S2626-PWR，端口带宽为100M

假如是1%，那么负载在是1M每秒吗？

另外， Input:  45237 input errors, 626 runts, - giants, - throttles

         30448 CRC, - frame, 0 overruns, 14163 aborts

         - ignored, - parity errors

这段话中626 runts 30448CRC 16163aborts等这些帧的处理方式，是什么原因导致它们出现的呢？

最后怎么判断，一个端口负载是否过大，尤其是这个端口是级联口的情况下？
