型号nexus 7k
sh int transceiver details 查看光信号强度的参数,不显示其中E10/44-48 口都是up的,已经接了设备,但是E10/44是有显示光衰,但是其他口不显示光衰的参数
这是为什么?

可以仔细的看一下,能够show出详细信息的模块是GLC-SX-MMD,注意最后的D,是DOM的缩写,而DOM是Digital Optical Monitoring的缩写,也就是带D的才可以看那些详细的信息,不带的就无法show出。这个结论不是万能的,1000M模块基本是这样,但是现在很多10G的模块已经不用这个规则了,会在模块的datasheet里直接告诉你支持DOM。
详细信息可以看该模块的datasheet,不过这个模块有点儿老,datasheet不太好找,我就不找链接了。
