交换机：Cisco 2960\Cisco 3560
1、查看IP对应交换机接口MAC地址
Switch_master#show arp | include 10.0.3.85
Internet 10.0.3.85 0 94de.80ff.c61a ARPA Vlan30
2、通过MAC地址查看对应交换机端口
Switch_master#show mac address-table dynamic address 94de.80ff.c6aa
Mac Address Table
-------------------------------------------
Vlan Mac Address Type Ports
---- ----------- -------- -----
30 94de.80ff.c61a DYNAMIC Gi1/0/3
Total Mac Addresses for this criterion: 1
3、通过接口查看对应的设备
Switch_master#show cdp neighbors gigabitEthernet 1/0/3
Capability Codes: R - Router, T - Trans Bridge, B - Source Route Bridge
S - Switch, H - Host, I - IGMP, r - Repeater, P - Phone,
D - Remote, C - CVTA, M - Two-port Mac Relay
Device ID Local Intrfce Holdtme Capability Platform Port ID
switch_slave Gig 1/0/3 140 S I WS-C3750X Gig 1/0/1
Total cdp entries displayed : 1
#对应接口为Cisco交换机，继续登陆交换机查询
switch_slave#show mac address-table dynamic address 94de.80ff.c6aa
Mac Address Table
-------------------------------------------
Vlan Mac Address Type Ports
---- ----------- -------- -----
30 94de.80ff.c61a DYNAMIC Gi1/0/11
Total Mac Addresses for this criterion: 1
#先查看对应端口下活动的MAC地址，来判断接口下的活跃的设备
switch_slave#show mac address-table dynamic interface gigabitEthernet 1/0/11
Mac Address Table
-------------------------------------------
Vlan Mac Address Type Ports
---- ----------- -------- -----
30 94de.80ff.c61a DYNAMIC Gi1/0/11
Total Mac Addresses for this criterion: 1
4、通过交换机端口查看对应接口设备IP
#查看接口对接设备的mac地址
switch_slave#show mac address-table dynamic interface gigabitEthernet 1/0/11
Mac Address Table
-------------------------------------------
Vlan Mac Address Type Ports
---- ----------- -------- -----
30 94de.80ff.c61a DYNAMIC Gi1/0/11
#通过mac地址查看你对应设备IP
switch_slave#show arp | include 94de.80ff.c6aa
Internet 10.0.3.85 0 94de.80ff.c61a ARPA Vlan30
