- 查看mac地址表
<Huawei>display mac-address
交换机转发原理
- 初始状态
- MAC地址学习
- 广播未知数据帧
- 接收方回应
学习,学习源mac地址,记录对应的接口号
广播,向除了数据来源之外的所有接口发送信息
转发,1对1进行数据传递
更新,超过300秒无任何数据通讯,mac地址记录将被删除
接口设备更换,或者接口down掉
快捷命令
ctrl + z 快速返回用户视图 等同于 return
ctrl + ] 快速退出系统
quit 一步步返回
三层交换机
三层交换机使用valn虚拟接口来配置地址，从而实现不通网段的通信

s5700为接口配置ip思路
1, 创建新vlan
2, 进入此vlan,配置ip
3, 将接口加入此vlan
