1、假如知道192.168.1.100主机地址，如何查看该主机连接交换机的端口 在核心交换机上运用：show arp | in 192.168.1.100 Internet 192.168.1.100 - 8480.2d0d.1ccc ARPA Vlan1 通过以上知道192.168.1.100主机的MAC地址 2、运用：TEST#show mac address-table address 8480.2d0d.1ccc Mac Address Table ------------------------------------------- Vlan Mac Address Type Ports - --- ----------- -------- ----- 18 8480.2d0d.1ccc DYNAMIC Gi1/0/48 以上可以知道该主机的地址是从G1/0/48接口学习过来的； 3、运用：show cdp neighbors /detail 查看本地G1/0/48接口连接情况； TEST#show cdp neighbors（通过detail可以看到对端设备IP地址） 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 LAB Gig 0/47 148 S I WS-C3750G Gig 2/0/2 4、查到连接具体设备的时候，登录此设备运用： LAB#show mac address-table address 8480.2d0d.1ccc Mac Address Table ------------------------------------------- Vlan Mac Address Type Ports ---- ----------- -------- ----- 18 8480.2d0d.1ccc DYNAMIC Gi1/0/9 从而得知192.168.1.100主机接在交换机LAB的G1/0/9口； |
