我们遇到了这样一种情况：在服务器所在的接口上收到了大量广播。我知道这不是正常行为；ARP 缓存应该记住 100 个地址，并且交换机设置为记住 ARP 4 小时。以下是我们在 2 天后在两个特定端口上看到的广播数量。

FastEthernet0/7 is up, line protocol is up (connected)
     Received 47681 broadcasts (0 multicast)
FastEthernet0/8 is up, line protocol is up (connected)
     Received 6321 broadcasts (0 multicast)

它们的配置方式相同：接口 FastEthernet0/7

 switchport access vlan X
 switchport mode access
 switchport port-security
 switchport port-security maximum 2
 switchport port-security mac-address sticky
 spanning-tree portfast

关于如何排除故障的任何想法？该问题在公司内几乎所有容纳服务器的接口上都很普遍。
