类似思科CDP的能看见邻居交换机。
- 使能SwitchA的全局LLDP功能。
- 在SwitchA上配置LLDP兼容CDP协议的功能，使得华为设备能够发现与之相连的其他厂商设备。
操作步骤
1、使能SwitchA的全局LLDP功能
[HUAWEI] **sysname SwitchA**
[SwitchA] **lldp enable**```
2、在SwitchA上配置LLDP兼容CDP协议的功能,在接口GigabitEthernet0/0/1上配置LLDP兼容CDP协议的功能。
```[SwitchA] **interface gigabitethernet 0/0/1**
[SwitchA-GigabitEthernet0/0/1] **lldp compliance cdp receive**
[SwitchA-GigabitEthernet0/0/1] **quit**
[SwitchA] **quit**```
3、验证配置结果
查看SwitchA的LLDP是否使能、CDP告警功能是否使能以及CDP告警的延迟时间是否为所配置的值。
>查看SwitchA的本地CDP信息。
```<SwitchA> **display cdp local**
