How Do I Locate An Ip Address How To Do So
At its core, an IP address is quite similar to a physical street address. First connect using putty to the core switch of the site that is doing the routing.IP Address basics. To find the port you must already have a good understanding of the network topology and have access to the switches CLI. This blog shows how to do so in a Cisco environment trying to find the IP address 10.1.4.40. It may just be that documentation is being created.

How Do I Locate An Ip Address Mac Address Table
In this example we found the port plugged into another switch which will likely be the case as end user devices are not likely to be plugged into your main core switch.Here we see the local interface port Ten 1/X/X is connected to another switch (which is model WS-C2960X switch) and the port that interconnects the two switches is Gi1/0/49.We have discovered that the device is not plugged into the core switch so we must connect to the next switch in line to find what port it may be plugged into.Connect to the other switch via putty in the same way we connected to the first.Run the same command as before to look at the mac address table.Here we find it in port Gi1/0/41. We could use the command “show cdp neighbor” to find if this port is connected to another switch. This is where knowing your network topology is important. Now show the mac address table of the switch by entering either (depending on the code versions):This will either give the exact port the device is plugged into or the port of the next switch in line it is plugged into. The example below shows searching for IP address 10.1.4.40.This will show the mac address of the device.
We do not see anything plugged into port Gi1/0/41 so this must be the port we are looking for. We can verify that with a show cdp neighbor command.From this switch we can see there are a few Meraki MR access points plugged into it, and we see our connection back to the core switch.
