Hello Gowthamraj
@obertigiovannicesare is right, you can’t ping a host using the MAC address. Ping uses the ICMP protocol and functions at Layer 3. It is designed to send echo requests and echo replies and uses IP addresses as the source and destination of these messages. More about ping can be found at the following lesson.
However, you can ping a particular MAC address “indirectly”. If you know the MAC address you’re looking for, you can find IP address that corresponds to it using Address Resolution Protocol (ARP). Once you find this, you can ping that IP address, and if you get a response, you can be sure that the MAC address of that host has been successfully reached.
Remember that IP communication relies on the underlying Ethernet communication that uses the source and destination MAC addresses, so all IP communications have an underlying Layer 2 component.
I hope this has been helpful!
