1、Smart1ink故障处理过程Smart1ink故他处理过程_一、开始首先检查SnIart1ink组状态是否正常。如果Smart1ink组正常,则检查相关设备的MAC和ARP/ND表项学习是否正确。若正确,则对数据报文进行流量统计,找到丢包的节点;若不正确,则检查Smart1ink保护V1AN、控制V1AN的配置,以及FIUSh报文的收发情况。如果Sn1art1ink组不正常,则检查接口的配置、接口和链路状态以及角色抢占配置是否正确。1、查看Smart1ink组状态Smart1ink的端口状态分为ACTIVE、STANDBY和DOWN,如果状态为DOWN,则表明端口故障。检查SnIart1in
2、k组中物理端口角色是否符合预期,状态是否异常。正常情况下,主端口处于ACTIVE状态,从端口处于STANDBY状态。命令:disp1aysmart-1inkgroupgroup-id例如:通过命令查看,可以确认SnIart1ink组中物理端口的角色和状态。H3Cdisp1aysmart-1inkgroup1Smart1inkgroup1information:DeviceID:c4ca-d9c-5138Preemptionmode:RO1EPreemptionde1ay:1(s)Contro1V1AN:10ProtectedV1AN:ReferenceInstance1MemberRo1eSt
