We can verify that with a show cdp neighbor command.įrom 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. AFAIK, the MAC address of the client does not change during. When a client moves from the area of one access point to another, it has to perform an access point change because its signal level went down.

Now, each client in the WLAN network has its own MAC address. Again, know the topology of your network to know if this is not another switch uplink. The WLAN access points are connected to each other by learning Ethernet switches. Run the same command as before to look at the mac address table. 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.Ĭonnect to the other switch via putty in the same way we connected to the first. 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. 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. 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. 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.

Now show the mac address table of the switch by entering either (depending on the code versions): This will show the mac address of the device. The example below shows searching for IP address 10.1.4.40. If it returns no entry, then generate traffic to the IP address by pinging the IP address and rerun the command. First connect using putty to the core switch of the site that is doing the routing. 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. There could be a compromised device generating too much traffic in your network.

Rather, the virtual mac addresses are assigned in order by how the SSID is assigned to the access point.It may be necessary to find which switch port a device is plugged into by using its IP address. Keep in mind, the assignment or order in which the virtual mac addresses are assigned in the above example has nothing to do with the WLAN IDs that are configured in the WLC.

NOTE: The VIRTUAL MAC ADDRESSES get reused by the access point on both the 2.4GHz and the 5GHz radios. 11 and so on.ĥGHz – Notice the sixteenth SSID ‘16’ is assigned the BASE RADIO MAC ADDRESS A9:10. Note: The access point base radio mac address ends in A9:10.Ģ.4 GHz – Notice the first SSID ‘01’ is assigned the BASE RADIO MAC ADDRESS A9:10.

I then fired up AirMagnet WiFi Analyzer Pro to conduct a capture. Cisco WLC access points have a limit of 16 SSIDs on each radio. I then enabled both the 2.4 GHz and 5 GHz radios. You can find the base radio mac address under WIRELESS->Select Access Point Pay very close attention to the 2.4GHz and 5 GHz radios and BSSIDs. What is interesting is how the virtual MAC addresses are selected. This allows for wireless network segmentation as well as for wireless clients to communicate via LAYER 2 with each access point BSSID.Ī Cisco access point takes the base radio mac address and then virtualizes the mac address as additional SSIDs are added. As you add SSIDs (Service Set Identification(s)) to an access point each BSSID (Basic Service Set Identifier) receives a virtual mac address.
