两台网点的H3C交换机由堆叠改为链路聚合 47和48口为聚合口 ，其他端口偶尔会报ARP限速的日志，但不多，只有47和48这两个做聚合的端口频繁报这个限速日志。

说明接口收到了大量的ARP报文，检查一下聚合口对接的网络是否存在大量客户端，若不是的话则有终端在发大量ARP报文，存在ARP攻击可能性。

两台48口交换机，其他的接口偶尔会有几个报这样的ARP限速，端口接的大部分是接终端机，有一个access端口下面描述是监控 display arp 该接口下收到12个arp，会不会是这个原因，导致链路聚合口频繁报这个日志信息。
access口下面可能还有个小交换机 上面接了多个终端 ，所以从这个接口显示有12个ARP ，但也不排除下面只接了一个终端，终端有问题
如果那个接口接了小交换机12个终端，加上其他接口发的arp包，会不会导致聚合口产生这样的日志，这个日志会不会就是正常现象，就是存在这么多终端发了大量的arp包？
产生这个日志的原因就是 有大量ARP包导致的，具体为啥还需要现场实际排查看看。
