问题描述：

华为交换机如何根据已知一个IP查他对应的MAC地址和交换机端口命令

解决方案：

华为交换机根据已知一个IP查他对应的MAC地址，已知终端ip：192.168.1.11

1.首先在核心交换机上dis arp | include 192.168.1.11
显示

IP ADDRESS MAC ADDRESS E XPIRE(M) TYPE INTERFACE VPN-INSTANCE VLAN
192.168.1.11 6xxx-9xxx-fxxx 12 D-0 GE0/0/11
Total:113 Dynamic:196 Static:0 Interface:4

找到ip：192.168.1.11对应mac地址为6xxx-9xxx-fxxx

查哪些IP已绑定的对应该的MAC地址
display current-configuration | include 192.168.1
显示

dhcp server static-bind ip-address 192.168.1.9 mac-address xxxx-xxxx-xxxx
dhcp server static-bind ip-address 192.168.1.108 mac-address xxxx-xxxx-xxxx
dhcp server static-bind ip-address 192.168.1.149 mac-address xxxx-xxxx-xxxx

2.然后找到对应接入层交换机dis mac-address 6xxx-9xxx-fxxx

[ACCESS]dis mac-address 6xxx-9xxx-fxxx
MAC Address VLAN/VSI/BD Learned-From Type
6xxx-9xxx-fxxx 16/-/- GE0/0/18 dynamic

找到mac地址：6xxx-9xxx-fxxx对应端口号GE0/0/18

查看接口对应有哪些mac地址

dis mac-address g0/0/23

MAC Address VLAN/VSI/BD Learned-From Type

3d9c-232d-091a 16/-/- GE0/0/23 dynamic
