35 解决单条链路故障问题-华三链路聚合

InLoopBack接口是一种虚拟接口。InLoopBack接口由系统自动创建，用户不能进行配置和删除，但是可以显示，其物理层和链路层协议永远处于up状态。InLoopBack接口主要用于配合实现报文的路由和转发，任何送到InLoopBack接口的IP报文都会被认为是送往设备本身的，设备将不再转发这些报文

一 在同一网段没有网关为啥能ping通

PC机配置信息

如果我中间的的链路断了,业务无法通过,这样可以吗？做为专业的网络工程师这样的操作不能发生的？

链路聚合的本质是提高网络的可靠性，模式分为静态模式和动态模式，一般采用动态模式

二 华三二层静态链路聚合

操作

命令

说明

进入系统视图

system-view

-

创建二层聚合接口，并进入二层聚合接口视图

interface bridge-aggregation interface-number

创建二层聚合接口后，系统将自动生成同编号的二层聚合组，且该聚合组缺省工作在静态聚合模式下

退回系统视图

quit

-

进入二层以太网接口视图

interface interface-type interface-number

多次执行此步骤可将多个二层以太网接口加入聚合组
