今天有用户cisco 3850插入多模千兆光模块后报错日志如下：
*Oct 18 13:48:54: %PLATFORM_PM-6-MODULE_ERRDISABLE:The inserted SFP module with interface name Gi1/0/18 is not supported
*Oct 18 13:48:54: %PM-4-ERR_DISABLE:gbic-invalid error detected on Gi1/0/18, putting Gi1/0/18 in err-disable state
*Oct 18 13:48:56: %LINK-3-UPDOWN: InterfaceGigabitEthernet1/0/18, changed state to down
思科官网查看文档后处理如下：
3850(config)# no errdisable detect causegbic-invalid
3850(config)# service unsupported-transceiver
