求助Cisco 12000系列POS口时钟问题（已解决）

redhat_fans

查看Cisco 12000系列的POS口（show int pos0/0），找了半天都没看到时钟配置项，不知道怎么回事，我的理解是：即便使用默认配置也应该会显示时钟模式的，POS口是10Gbit/s速率，烦请各位高手指点迷津，谢谢！

默认地 时钟配置是line，show run是看不到的，你show controller应该能看到

看了一下show interface pos 和 show controller pos 两个命令都没有显示时钟配置

    时钟属于底层的配置，不在show int里，而是在show controller里，我从你的output里看见了“CLOCK RECOVERY”，说明是从传输网络获取时钟的，这个配置是默认的，也是正确的。

    谢谢，已经找到了，确实是在sh controller det 里，要看详细的描述。
