思科交换机通过ip或Mac查询所在交换机的哪个端口

1、进入三层交换机 查询 ip地址对应的Mac地址。（反查也可以）

Core1#show arp | include 10.9.8.39
Internet 10.9.8.39 86 cc28.aaa8.18ba ARPA Vlan908

 2、查询cc28.aaa8.18ba地址的arp信息是从哪个接口学习到的

S9#show mac address-table | include cc28.aaa8.18ba 
 908    cc28.aaa8.18ba    DYNAMIC     Gi1/0/8

3、查询该交换机的网管信息

S9#show cdp neighbors gigabitEthernet 1/0/8 detail
