A few different ways

by Toivo Talikka In reply to how do i know, my pc conn ...

If your switches have a management interface, that may have a menu option which lists the MAC address of each device connected to the switch. You will see the MAC or the Physical Address if you right click the Local Area Connection and then select Status - Support - Details. Another way is to type in ipconfig /all in the command prompt.

Alternatively, if you do not have an uptodate cabling diagram, or if the wall outlets and the patch panel outlets are not marked, you need to jot down all the ports on each switch which are lit. Disconnect the network cable from your PC, go back to the rack and check the lights on the switches to find out which additional port is now off.

You can also get hold of a cabling technician with a tester unit which will be connected to the wall outlet to which your PC is connected. The technician will then swipe his magic wand on the patch panel and it will start beeping when it finds the signal from the tester.

Cisco stuff

by CG IT In reply to A few different ways

you can assign switches to ports via MAC address. The Web GUI will also tell you what address is on what switch port. even another way is to VLAN.

The most important question though is How do you know who's where?

Documentation. If you don't have any, then you have to create it.

To Track a Host

by SaeedZam In reply to how do i know, my pc conn ...

hopefully you have already found out how to track a network device by now.. if not...

Here is what you do to track a network device on a switch without physically mapping out the cables (if you know the IP address):

1. Log into the Cisco Switch

2. Ping the IP address of the device you are trying to track

3. show arp | include (ipaddress of device you are trying to locate)

4. copy or write down the mac address

5. show mac-address address xxxx.xxxx.xxxx (mac address that you copied above)

This will tell you exactly where the device is plugged in. If it points to your uplink ports, that means the device is on another switch.
You only have 3 switches so you can try this on one switch at at time to find the device; otherwise you can do this on your distribution switch to see which closet switch you need to go to.
