现场两台交换机做的堆叠,想增加bfd配置,然后将1/0/47----2/0/47,2/0/47----2/0/48连接起来时发现接口不up,两个46口互连也不up。但是接口直接连接服务器就能up,服务器网卡是25G。
此交换机接口大部分是25G接口,接的25G光模块,接其他设备都能up。 目前发现互连的接口除了堆叠的100G口,都不能up。

查了光模块适配性没问题,光收发正常。

查看端口的fec mode不一致:
Twenty-FiveGigE1/0/47
Current state: DOWN
Line protocol state: DOWN
IP packet frame type: Ethernet II, hardware address: hhhh-hhhh-hhhh
Description:
Bandwidth: 25000000 kbps
Loopback is not set
Media type is optical fiber, port hardware type is 25G_BASE_SR_SFP28
FEC mode: RS-528
Twenty-FiveGigE2/0/47

Media type is optical fiber, port hardware type is 25G_BASE_SR_SFP28
FEC mode: BASE-R
需要进端口视图手动修改下,“port fec mode base-r/rs-fec” ,两侧要一致,建议调整成rs-fec,然后再对接;
端口历史上插过电模块或者电缆都是有可能刷新过FEC模式、或者历史上有人调整过,都有可能引起FEC mode变化的;
