Hi CAn u help me pls.I just want to know which port I have connected my pc.
when i do sh ip arp..will get as follows,
Protocol Address Age (min) Hardware Addr Type Interface
Internet 1.1.1.1 13 0026.9914.e63f ARPA Vlan150
Internet 192.168.80.80 158 0026.9914.e63f ARPA Vlan150
Internet 192.168.80.81 227 0026.9914.e67f ARPA Vlan150
Internet 192.168.40.50 103 0026.9914.e63f ARPA Vlan150
Internet 192.168.80.77 114 0026.9914.e67f ARPA Vlan150
Internet 192.168.80.68 181 0026.9914.e63f ARPA Vlan150
Internet 192.168.80.160 106 0026.9914.e63f ARPA Vlan150
Internet 192.168.150.12 50 0027.0d86.9cc1 ARPA Vlan150

since my pc’s ip is 192.168.80.160, mac address is 0026.9914.e63f acording to the above details(actually this is not my pc’s mac.I checked it) .so now

FirstFloor_SW1#sh mac address-table | include 0026.9914.e63f
20 0026.9914.e63f DYNAMIC Te0/1
31 0026.9914.e63f DYNAMIC Te0/1
33 0026.9914.e63f DYNAMIC Te0/1
50 0026.9914.e63f DYNAMIC Te0/1
60 0026.9914.e63f DYNAMIC Te0/2
70 0026.9914.e63f DYNAMIC Te0/1
80 0026.9914.e63f DYNAMIC Te0/2
150 0026.9914.e63f DYNAMIC Te0/1

And Te0/1 and Te0/2 are uplinks.So what is the solution??How to find the port which I have connected to my pc??

thx weer

Go back to the point of: “know your network”

As switch1 and switch3 show you on Fa0/24 i assume that this is the uplink both use, therefore port13 on switch2 it is for you.

Is there a method if you don’t have access (telnet) to the switch? Like the Fluke LinkRunner device.
