H3C S5500-SI LLDP基本功能的典型配置

一、  组网需求：

NMS通过以太网与Switch A相连，Switch A分别通过GigabitEthernet1/0/1、GigabitEthernet1/0/2与MED设备、Switch B相连。

在Switch A和Switch B的相应端口配置LLDP功能，使得NMS可以对Switch A链路的通信情况进行判断。

二、  组网图：

三、  配置步骤：

1. 配置Switch A

# 全局使能LLDP功能。

<SwitchA> system-view

[SwitchA] lldp enable

# 分别在GigabitEthernet1/0/1和GigabitEthernet1/0/2端口使能LLDP功能并配置其工作模式为rx。

[SwitchA] interface gigabitethernet1/0/1

[SwitchA-GigabitEthernet1/0/1] lldp enable

[SwitchA-GigabitEthernet1/0/1] lldp admin-status rx

[SwitchA-GigabitEthernet1/0/1] quit

[SwitchA] interface gigabitethernet1/0/2

[SwitchA-GigabitEthernet1/0/2] lldp enable

[SwitchA-GigabitEthernet1/0/2] lldp admin-status rx

[SwitchA-GigabitEthernet1/0/2] quit

2. 配置Switch B

# 全局使能LLDP功能。

<SwitchB> system-view

[SwitchB] lldp enable

# 在GigabitEthernet1/0/1使能LLDP功能并配置其工作模式为tx。

[SwitchB] interface gigabitethernet1/0/1

[SwitchB-GigabitEthernet1/0/1] lldp enable

[SwitchB-GigabitEthernet1/0/1] lldp admin-status tx

[SwitchB-GigabitEthernet1/0/1] quit

3. 验证配置结果

# 在Switch A上显示全局和端口的状态信息。

[SwitchA] display lldp status
