网络工程师在做日常网络维护的时候可能经常会遇到这种情况：发现某个IP地址流量特别大，或者收发特别异常的时候，想找出该IP对应的用户出来。而在思科交换机搭建的环境中，是能做到通过对方MAC/IP地址来查找对端对应的交换机端口的，具体步骤如下： 　　假设对端的MAC地址为：192.168.1.101 　　在中心交换机（核心层交换机或汇聚层交换机）上输入: switch-6509#show ip arp | in 192.168.1.101 Internet 192.168.50.47 2 0011.2233.4455 ARPA Vlan50 　　在ARP表中我们找到了和192.168.1.101对应的MAC地址，如果要根据MAC地
