Catalyst 9300配C9300-NM-4G:显示OEM 1000BASE-LX SFP但端口一直是notconnect

楼主部署了几台装有C9300-NM-4G网络模块的全新Cisco Catalyst 9300交换机,把GigabitEthernet1/1/1配置为trunk并启用,但换了好几个SFP都无法建立链路。'show interfaces'显示'GigabitEthernet1/1/1 is down, line protocol is down (notconnect)',media type是'1000BaseLX SFP',接口重置了6次。'show interface transceiver detail'里的DOM数据看起来正常:Tx功率-5.2 dBm,Rx功率-4.7 dBm,都在阈值范围内。'show idprom interface g1/1/1'识别出模块厂商为'OEM',型号M-SFP-LX-C,1000BASE-LX,1310nm单模,10公里,DDM已实现。抓取到的文本只有帖子正文,后面十二条回复没有采集到。

• 硬件: Cisco Catalyst 9300,Cisco C9300-NM-4G网络模块
• 收发模块: OEM M-SFP-LX-C(1000BASE-LX,1310nm,10公里),其他未说明型号的1G SFP
• 封装形态: SFP

症状/报错信息:

GigabitEthernet1/1/1 is down, line protocol is down (notconnect)
media type is 1000BaseLX SFP
Tx -5.2 dBm / Rx -4.7 dBm within thresholds but no link
6 interface resets
Vendor Name: OEM in idprom
