OTN排故思路
打环 打环 再打环 简单--->复杂
前奏
开局简单核查命令：

针对具体业务查询，业务类型有：EOS业务 EOO业务 ，方式从上联口到下联口逐个节点向下查询
2. 目前多数业务都采用SDH+OTN的方式，所以从这涵盖基本。 ↩
- 现在有条业务通过8AT2对接华为大网，排查我司设备是否问题，可以这样操作：
节点1 OTU口有无告警
GPN7600(otn)# ioctl otu show 13/1 ## 查看OTU接口信息
节点2 oduk时隙有无告警
GPN7600(otn)# ioctl odu1 show 13 otu 1/1 ## 查看OTU接口下odu1信息
节点3 VP-SDH口有无告警
GPN7600(otn)# ioctl odu1 show 13 sdh 1/1 ## 查看sdh接口下的odu1信息
节点4 VP-SDH对应高阶有无告警
GPN7600(config-msap)#ioctl hpoh show 13/1/1 16 ## 查看高阶告警
节点 5 VP-SDH对应低阶有无告警
GPN7600(config-msap)#ioctl lpoh show 13/1/1/1 63 ## 查看低阶告警
节点6 VCG收发、扰码是否正常
GPN7600(config)# interface vcg 1/1
GPN7600(vcg-1/1)# show current-state ## 查看vcg告警
节点7 端口是否有up 是否有流量
GPN7600(config)# config msap
GPN7600(config-msap)# ioctl vcg info 1/1 ## 查看vcg控制字及端口双模模式
