Utilizing the show tech-support slowdrain Command
The show tech-support slowdrain is a single command on Cisco MDS switches that aggregates all the other commands normally necessary for troubleshooting congestion into a single output. From its output, you can find the individual commands needed for troubleshooting. 在 Cisco MDS 交换机上,show tech-support slowdrain 是一条单独的命令,它将排除拥塞故障通常所需的所有其他命令汇总到一个输出中。从其输出中,您可以找到故障排除所需的单个命令。
The following are best practices for collecting the show tech-support slowdrain command output: 以下是收集 show tech-support slowdrain 命令输出的最佳实践:
1. Collect the output of this command from all the switches. This is because before investigating a congestion problem, it is impossible to determine in advance, the source and cause of congestion or even all the victims. Having the information from all the switches allows the investigation to go where the congestion indications lead. 收集所有交换机的该命令输出。这是因为在调查拥塞问题之前,不可能事先确定拥塞的来源和原因,甚至不可能确定所有受害者。掌握了所有交换机的信息,就可以根据拥塞迹象进行调查。
2. Collect the outputs from all the switches in the fabric at the same time. This allows time correlation of the same events across multiple switches. 同时收集结构中所有交换机的输出。这
