或者查看MAC地址對應的端口
display mac-address

2.通過查詢配置信息查詢商品名字
display current-configuration
interface GigabitEthernet6/0/42
port access vlan 110
#
interface GigabitEthernet6/0/43
port access vlan 110
#
interface GigabitEthernet6/0/44
port access vlan 20
#
interface GigabitEthernet6/0/45
#
interface GigabitEthernet6/0/46
#
interface GigabitEthernet6/0/47
#
interface GigabitEthernet6/0/48
port access vlan 220
3.查看端口狀態

4.對于一個端口對應多個IP的需要查到這個網卡地址
先登陸第一臺路由器，查看IP

再登陸第二臺路由器

--- 16 mac address(es) found in vlan 10 ---

這樣就可以查出10.248.2.13這個IP用的是GigabitEthernet6/0/33這個端口
