通常我使用以下命令来显示端口利用率：
monitor port 1/1/8 rate interval 5
例如，这将导致每隔几秒产生以下输出：
===============================================================================
Monitor statistics for Port 1/1/8
===============================================================================

1000Mbps 端口如何Utilization (% of port capacity)计算？
对于 1000Mbps 端口，解决方案似乎不是 (octets*8)/1E9。例如，在 t = 5 秒时，(1185742 个八位字节 * 8)/1E9 * 100% = .95% 而不是 1.11%。
我认为诺基亚/ALU 使用的数学有一些我没有看到的东西。
