小白白,当你看到这篇博客,那么你需要系统学习,多看看视频,别自己懵逼乱撞了
实验:
1.配置IP
为什么无法配置IP?
配置vlanif,完成和路由器的直连通信,然后远程管理
[SW1]interface g0/0/10
[SW1-GigabitEthernet0/0/10]ip add
[SW1-GigabitEthernet0/0/10]ip address 10.1.1.254 24 //交换接口无法执行配置IP地址的命令,因为这是一个二层接口。一些路由器上安装了2层板卡也会出现此问题(ensp的1220之类的ethernet接口)
[SW1]display interface g0/0/10 //验证命令
GigabitEthernet0/0/10 current state : UP
Line protocol current state : UP
Description:
Switch Port, //2层接口!!
真机可以支持2层接口转换成3层接口
interface GigabitEthernet0/0/10
undo portswitch //2层接口变成3层接口,模拟器支持该命令,但没有效果。反之亦然.如果想把路由接口变成2层接口也是如此,模拟器嘛,请不要大惊小怪
[SW1-GigabitEthernet0/0/10]ip add 10.1.1.254 24 //模拟器配置地址依旧报错。在物理接口不能配置IP地址,但是可以使用vlan接口
还有联系乾颐堂官网
非常不推荐把2层接口变为3层接口,会让广播域增加太多。推荐使用vlanif接口
[SW1]interface Vlanif 1
[SW1-Vlanif1]ip add
[SW1-Vlanif1]ip address 10.1.1.254 24
[SW1-Vlanif1]

ENSP如何保存配置,使得下次启动时依旧还有配置
save
The current configuration will be written to the device.
Are you sure to continue?[Y/N]y //在华为设备保存配置
然后点击ENSP的第四个按键“保存”
确保万无一失,在关闭ENSP时再保存
