盛科CTC8096端口速率40G切换10G配置

Felven2026-05-13 11:26

1、背景介绍

公司现有交换模块上采用了盛科的CTC8096 40G交换芯片，其中有两路40G通过后板光模块直出，用于跨机箱互联，现在有新需求，需要将后出的40G全部改为10G直出。

2、配置过程

原来的状态在盛科的CTCSDK下通过show port mac-link命令看到的结果如下，全部都是40G

经过和原理图对比确认，两路后出的端口是port 8和port 12，对应serdesID为8-15

因为一路serdes最多支持10G，而一路40G是四路10G组合形成的，改成10G就是将原来组合在一起的serdes进行拆分，每个serdes独立成为一个port修改datapatch_cfg.txt文件，将原来8-15的serdes模式改成XFI 修改SERDES_MODE=1，SERDES_SWITCH从1变成0（意思为不进行组合）

修改后的datapath_cfg.txt文件如下

同时针对新产生的端口，为了能和其他端口互通，需要放在一个VLAN内，这个可以通过修改上电的启动脚本实现，在FFE_Param_startup.cfg(注：盛科原来的脚本名称叫startup.cfg，这里是因为sdk代码内把读取脚本名称改了 )中最前面添加下面代码。

bash 复制代码

port 13 vlan-filtering direction both enable

port 14 default vlan 10
vlan add port 14 vlan 10

port 14 vlan-filtering direction both enable

port 15 default vlan 10
vlan add port 15 vlan 10
port 15 vlan-ctl drop-all-tagged
port 15 vlan-filtering direction both enable

重启后执行show port mac-link查看结果如下：

以上就实现了后出两路40G变成8路10G的配置。
