# 5.交换机作为SSH客户端登录出错

使用华三交换机作为ssh客户端登录其他设备，报错如下,提示设备本地保存的密钥和对方返回的密钥不同，

```
<H3C> ssh 192.168.1.1
Username: admin
Press CTRL+C to abort.
Connecting to 192.168.1.1 port 22.
The server's host key does not match the local cached key. Either the server administrator has changed the host key, or you connected to another server pretending to be this server. Please remove the local cached key, before logging in!
```

### 1.查看本地保存到密钥

```
[H3C]display ssh client server-public-key

### 2.删除本地保存的密钥
