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

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 |
