1. 什么是lldpd？ LLDP 可以让你准确的知道服务器所连接的交换机端口号。 LLDP是一种工业标准协议，用于取代EDP或CDP等专用链路层协议。LLDP的目标是提供一个inter-vendor兼容机制，向相邻网络设备发送链路层通知。 lldpd是一个LLDP协议的一种实现，给各种Unixes使用。除此之外，它还支持一些专有协议。 1.1. lldpad与lldpd的对比实现交换机端口的抓取，目前我知道的有两种工具，一种是lldpad，另一种是lldpd。 这两个工具做了一下对比，最终选择了lldpd。原因如下： 1.2. 安装lldpd 需要先配置好配置好epel-release源，然后直接yum安装即可。 [root@controller ~]# yum install -y epel-release , \8 o j u T$ ?1 \8 q2 t) x& ]' W
