在Tunnel路径的各个节点上检查告警,查看网管是否有active/linkDown的告警,记录时间T1。然后执行display interfaceinterface-type interface-number命令,查看Last line protocol up time字段,记录该字段显示时间为T2。 如果T1>T2,说明Tunnel经过的物理接口问题导致Tunnel Down,请参考物理接口故障问题。
排查接口物理状态Down的原因。 Tunnel接口物理状态为Down,通常情况下为本端配置问题,需要根据隧道接口下配置进行故障排查。 Tunnel接口的配置信息如下:# interface Tunnel1 //一维口模式 ip address 172.22.1.1 255.255.255.0 //Tunnel接口IP地址 tunnel-protocol gre //Tunnel接口配置绑定GRE协议 keepalive period 3 /...

Administratively down:网络管理员在该接口执行了shutdown命令。 一般情况下,Tunnel接口刚创建时其物理层状态就为UP。 Line protocol current state Tunnel0/0/2的接口协议状态: UP:接口网络层协议正常运行。 DOWN:接口网络层协议没有正常运行。 Description
