Ethernet0/0/11              up    up       0.05%  1.30%          0          0 

2、display mac-address #来查看端口下的MAC 

<Quidway>dis mac-address 
MAC address table of slot 0:

3、display arp         #找IP对应的MAC，通过IP后面的端口号就可以知道二层某个端口下所连接的设备信息。 

<Quidway>dis arp 
IP ADDRESS      MAC ADDRESS  EXPIRE(M) TYPE INTERFACE      VPN-INSTANCE
