Brocade 交换机上的端口

问题描述

Rx利用率达到高且defALL_TARGET_PORTSRX_90 在中触发规则 errdump。
Sfpshow 输出报告建议范围内的Tx和Rx功率。

============= Slot 3/Port 27: ============= RX Power: -0.8 dBm (833.4uW) TX Power: -0.6 dBm (877.8 uW)

Porterrshow 不会报告任何错误、因为在上传日志之前已清除统计信息。

portstatsshow 输出显示的副计""值非常高tim_txcrd_z、这再次清楚地表明端口已过度利用。
Brocade交换机上的portstatshow命令输出中的"Tim txcrd_z"是什么意思？ portstatshow命令输出中的"tim_xcrd_z "（Time TX Credit Zero (2.5U ticks)）参数告诉我们、由于传输BB (缓冲区到缓冲区)信用值为零、端口无法传输帧的次数。
