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/ X3 i$ g6 O1 f6 o L

x710关闭lldp- 现象症状：8 i- G1 n1 e; _! |+ v- Z" z
使用x722 LOM，当lldpad启动时，lldptool -L adminStatus = rxtx -i < interface name>然后lldptool -tni < interface name>运行时，NIC端口连接到启用了LLDP的交换机，不会返回LLDP信息。 （其中LLDP =链路层发现协议） - 解决办法：2 A- |( C$ v" J' `: v- q. T
运行commnand " echo lldp stop > / sys / kernel / debug / i40e / < PCIe路径> / command" ;.由于LOM沒有FCoE功能，沒有DCBx要求，所以沒有真正的功能影响。 （FCoE =以太网光纤通道） - 附加信息：
, l [ v8 I! x: d% i2 B9 a$ h5 M0 K
根据Intel设计，x722适配器默认处理所有LLDP流量，LLDP流量将不会转到主机CPU，除非使用在x722中停止LLDP功能的命令。
