I have ip address of one of my remote server I cannot login remotely. I have the IP address and I and trying to find the mac address or interface that connected to the server. Could you tell me the command or the way to find the Switch port or mac address if you only have ip address. Type 'arp -a' in the command prompt. This lists a number of MAC addresses with the associated IP addresses. Since you have the MAC address, scroll down the list to find the associated IP address. The MAC address is shown in the 'Physical Address' column with the IP address in the 'Internet Address.
We can find mac address (physical address) of a computer using the command ‘getmac‘. This can be used to get mac address for remote computers also. Below are few examples on how to use this command. It works on XP, Vista, Windows 7, Server 2003 and Server 2008 operating systems.
Get mac addresses from CMD
Just run the command getmac to get the mac addresses. Find an example below.
This command does not show mac addresses for the network connections which are disabled. You can run ncpa.cpl and check which NICs are disabled. Further, I have received comments that this command does not help identify the mac address for a specific device. For example, if I need to get the mac address for my WiFi card, output of getmac command is not helpful. We can use ipconfig command to deal with this.
Get mac address of a remote computer
We can retrieve the mac addressses for a remote computer using nbtstat command.
Example:
Alternatively, We can run the below command to retrieve the mac addresses of a remote computer.
remote_computer : Full name of the remote computer or IP address
username and password are of the account on the remote computer.
Example:
If you do not want to specify the password, you can skip /p parameter. You will be prompted to enter the password and the command execution will take place after that.
Errors:
Using getmac command we can retrieve the mac addresses of the machines running windows OS only. If you try this for a Linux machine you would get the error 'The RPC server is unavailable.'
If you provide incorrect password, the command would fail with the error message 'Logon failure: unknown user name or bad password.'

This post explains getting MAC address and IP address of devices connected to ESP8266. Typically, the MAC address is only visible on each end of a 'hop' in a packet so if you are going from some device via WiFi through the router to some other device, the MAC address you would see would be from your device and the router. The router will typically have a table of IP addresses and associated MAC addresses for those devices that it has handed out an IP address to via DHCP.
A media access control address (MAC address) of a device is a unique identifier assigned to network interfaces for communications. In this Example we will get MAC address of all connected devices to the ESP8266. ESP8266 acts as WiFi access point.
