一、SSH配置
[Huawei]rsa local-key-pair create #创建SSH key
[Huawei]aaa
[Huawei-aaa]undo local-user policy security-enhance #关闭用户安全策略
[Huawei-aaa]local-user admin password irreversible-cipher xxxxxxxxxx #设置用户密码
[Huawei-aaa]local-user admin service-type ssh
[Huawei-aaa]local-user admin user-group manage-ug
[Huawei]stelnet server enable #开启SSH服务
[Huawei]ssh server acl 2000 #ssh服务上调用acl
[Huawei]ssh server-source all-interface #在所有接口上启用ssh，先开启此命令才能进vty接口
[Huawei]user-interface vty 0 4
[Huawei-ui-vty0-4]authentication-mode aaa
[Huawei-ui-vty0-4]user privilege level 3
[Huawei-ui-vty0-4]protocol inbound ssh
二、配置还原
[Huawei] ssh client first-time enable
[Huawei] scp root@[backupserver]:/root/backup.cfg flash:/backup.cfg #拷贝配置文件到交换机
[Huawei] reset saved-configuration #清除配置
[Huawei] copy flash:/backup.cfg flash:/startup.cfg
注：
如提示error flash:/startup.cfg is protected错误请先清除配置
<Huawei> startup saved-configuration flash:/startup.cfg #修改交换机默认启动加载的配置文件为startup.cfg
[Huawei] clear configuration interface GigabitEthernet0/0/1 #清除接口配置
[Huawei-GigabitEthernet0/0/1] clear configuration this #清除接口配置
