问题描述
问题现象：将光模块从旧设备S7506E换到新设备S6805上，接口都是up的，但是无法学习到ARP和mac地址
1、接口up

过程分析
1、做过替换测试，将这块光模块替换到其他接口，还是学会不到arp和mac地址；重新插入另外一块光模块到该接口也学习不到arp和mac地址；将这块光模块插回旧设备7506E就能正常学习到arp和mac地址
2、 查看接口光模块是H3C原厂模块
Ten-GigabitEthernet1/0/36 transceiver manufacture information:
Manu. Serial Number : 210231A962X16A018635（过保）
Manufacturing Date : 2016-10-28
Vendor Name : H3C
3、光模块型号：SFP-GE-LX-SM1310-D；查看官网也是适配的
4、收集debugging arp packet，发现设备只收到一个arp请求报文，没有回应一个ARP应答报文
<AS_JZSJY_HJ_S6805-IRF>*Dec 15 15:11:53:946 2022 AS_JZSJY_HJ_S6805-IRF ARP/7/ARP_RCV: Received an ARP message, operation: 1, sender MAC: 90e7-1009-0d0a, sender IP: 10.3.159.156, target MAC: 0000-0000-0000, target IP: 10.3.159.183
5、接口收光弱，接近阈值
Ten-GigabitEthernet1/0/36 transceiver diagnostic information:
Current diagnostic parameters:
Temp.(¡ラ Voltage(V) Bias(mA) RX power(dBm) TX power(dBm)
28 3.35 14.75 -18.89 -6.05
Alarm thresholds:
Temp.(¡ラ Voltage(V) Bias(mA) RX power(dBm) TX power(dBm)
High 85 3.60 60.00 -3.00 -1.00
Low -5 3.00 0.00 -19.00 -11.00
解决方法
SFP+口使用除了SFP-GE-T、SFP-GE-T-D之外的其他千兆SFP模块与对端连接时，对端需要关闭自协商（autonegotiation）功能。
端口安装SFP-GE-T、SFP-GE-T-D模块时仅支持1G速率。
