1、SmartLink故障处理过程SmartLink故他处理过程_一、开始首先检查SnIartLink组状态是否正常。如果Smart1.ink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Smart1.ink保护VLAN、控制VLAN的配置,以及FIUSh报文的收发情况。如果Snlart1.ink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SmartLink组状态Smart1.ink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SnIar
2、t1.ink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:displaysmart-linkgroupgroup-id例如:通过命令查看,可以确认SnIart1.ink组中物理端口的角色和状态。H3Cdisplaysmart-linkgroup1Smartlinkgroup1information:DeviceID:c4ca-d9c-5138Preemptionmode:ROLEPreemptiondelay:l(s)ControlVLAN:10ProtectedVLAN:ReferenceInstance1Member

8、5、查看MAC、ARP/ND表项学习是否正确当发生链路切换,如果发生业务中断,则需要检查与成员端口相连设备的MAC、ARP/ND表项是否正确。6、检查数据报文流量统计如果MAC、ARP/ND表项学习正确,但业务数据转发不通,则对业务报文做流量统计,查看报文在哪里被丢弃。Administrator2015-12-13 09:31:307、检查保护VLAN配置一如果MAC、ARP/ND表项学习不正确,则检查是否正确配VLAN的映射关系,并且在SmartLink组中调用。命令:displaystpregion-configurationdisplaysmart-linkgroupgroup-id例如
