配置LLDP兼容CDP协议的功能示例

组网需求

图1所示,华为设备SwitchA和其他厂商设备SwitchB之间通过一个未知网络相连。NMSSwitchASwitchB之间路由可达且SNMP配置完成。

网络管理员希望在NMS上可以获取到SwitchASwitchB之间的二层配置信息,用于了解网络的详细拓扑信息、判断网络中是否有配置冲突的情况。

配置思路

采用如下的思路配置LLDP兼容CDP协议:

1.  使能SwitchA的全局LLDP功能。

2.  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> system-view

[HUAWEI] sysname SwitchA

[SwitchA] lldp enable

2.  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SwitchALLDP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
