配置LLDP兼容CDP协议的功能示例
组网需求
如图3-14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。NMS与SwitchA和SwitchB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SwitchA和SwitchB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。
操作步骤
- 使能SwitchA的全局LLDP功能
<Quidway> system-view [Quidway] sysname SwitchA [SwitchA] lldp enable
- 在SwitchA上配置LLDP兼容CDP协议的功能
# 在接口GigabitEthernet1/0/1上配置LLDP兼容CDP协议的功能。
[SwitchA] interface gigabitethernet 1/0/1 [SwitchA-GigabitEthernet1/0/1] lldp compliance cdp receive [SwitchA-GigabitEthernet1/0/1] quit [SwitchA] quit
- 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。
