N9K-C9508-FM-E2

[xudan]

N9K-C9508- 有五块交换矩阵（FM-E2），有一块矩阵在show module命令行下显示 powered-dn，C9508 vPC等其它功能均不能正常运行，请问各位大侠有解决方案么

[Rps-Cheers]

您提供的信息太少了，vPC相关端口是在powered-dn的板卡上吗？如果是硬件问题，建议尽快联系供应商RMA。

你好，感谢回复，2台9508做的vPC，在测试时有热插拔线卡和引擎的动作，以下是报错信息和日志

这个log提示是Fabric module不支持，和vpc的的功能正常与否没什么关系，我看你附件的log里面9508-1的 show vpc有一部分是正常的，vpc的问题还是检查一下配置情况吧；

Fabric powered-dn的问题是由于n9k的线卡混插的原因，目前你的两台9k 1,2槽位是两块N9K-X97160YC-EX，3,4槽位是两块N9K-X9736C-FX，仅有N9K-X9736C-FX是需要5块Fabric来达到最大带宽支持的，N9K-X97160YC-EX仅支持4个Fabric module，两种类型线卡导致了只能有4块fabric可用。

如果需要5个fabric同时工作，需要是纯N9K-X9736C-FX的线卡，N9K-X97160YC-EX不支持
