show ip arp命令可以得到IP地址与MAC地址的对应关系，show mac-address-table可以得到MAC地址与端口的对应关系，根据这两组对应关系，大家就可以得到IP地址与端口的对应关系。
命令总结：
1.静态绑定arp表项后，无老化时间
R2(config)# arp 192.168.1.2 cc01.0614.0000 arpa
2.show ip ARP —查看arp表
R2# show ip arp
Protocol AddressAge (min) Hardware Addr Type Interface
Internet 192.168.1.1 1 cc00.0614.0000 ARPA FastEthernet0/0
Internet 192.168.1.2 – cc01.0614.0000 ARPA
Internet 192.168.1.3 0 cc02.0614.0000 ARPA FastEthernet0/0
Internet 192.168.1.4 1 cc03.0614.0000 ARPA FastEthernet0/0
R2#
3. show mac-address-table—查看mac-address-table,适用于二层接口
4.修改arp老化时间
R2(config)#int f0/0
R2(config-if)# arp timeout ?
<0-2147483> Seconds
5.静态绑定mac-address-table
R1(config)# mac-address-table static cc01.0614.0000 interface fastEthernet 1/2 vlan 2
6.清除arp缓存，刷新arp表
R1# clear arp-cache ?
A.B.C.D IP address
interface Clear the entire ARP cache on the interface
vrf Clear entries for a VPN Routing/Forwarding instance
<cr>
R1# clear arp-cache interface fastEthernet 1/2
R1#
7.no mac-address-table static 后需要刷新mac-address-table
clear mac-address-table
