一個查埠連線交換機的一條線的技術

1.一個查埠連線交換機的案例:

到核心層，查到mac
Internet 10.2.13.79 2 001c.2326.e3f5 ARPA Vlan131
透過mac表，查到進入埠
* 131 001c.2326.e3f5 dynamic Yes 10 Po12

Port-channel12 unassigned YES NVRAM up up
查到 進入埠所連是哪個交換機
ALY-HX-2#show int Port-channel12
Port-channel12 is up, line protocol is up (connected)
Hardware is EtherChannel, address is 0015.6251.5837 (bia 0015.6251.5837)
Description: Link to AJH-MZHJ002

查到這個交換機的ip

-------------------------
Device ID: AJH-MZHJ002
Entry address(es):
IP address: 10.2.6.21
Platform: cisco WS-C3750G-12S, Capabilities: Switch IGMP
Interface: GigabitEthernet9/4, Port ID (outgoing port): GigabitEthernet1/0/10
Holdtime : 115 sec

10.2.6.21這個交換機是一個匯聚層,透過拓樸圖，知道它連線七樓的.121的機器,
登入到121機器， show mac-add查出它是連線如下埠

131 001c.2326.e3f5 DYNAMIC Fa0/9
