一台Quidway S3952P-SI交换机，保存后配置会丢失，交换机直接进入初始化配置。查看启动选项，当前保存的配置为NULL，如下：

[cheshisw] dis startup
UNIT1:
Current Startup saved-configuration file: NULL
Next main startup saved-configuration file: flash:/vrpcfg.cfg
Next backup startup saved-configuration file: NULL
Bootrom-access enable state: enabled

重启交换机，按[crtl]+[B]，会出现如下图的界面。

锐捷交换机的光电复用口 的转换，前阵子是把光口改成了电口来使用（默认开启的是电口），现在这交换机上有三个口又要改成用当电口来使用，光口改电口是使用med fiber参数来调整，通过med ?参数查看除fiber以外的值，发现只有copper和fiber，很明显电口的值就是copper，如下图：

这样，通过使用med copper参数就可以将光口改为电口了，这里我是修改gig 0/2-4口，步骤如下：

shixunlou5750#conf
Enter configuration commands, one per line. End with CNTL/Z.
shixunlou5750(config)#int range gig 0/2-4
shixunlou5750(config-if-range)#med copper
shixunlou5750(config-if-range)#end
shixunlou5750#wr

Building configuration…

[OK]
