How to get mac address of cisco switch
Lets start with an IP address on hand.
Find port by Device Mac Address –
If you have an IP address on hand quickly ping and check if the device is pingable. If yes, then simply logon to one of your core switches or routers and do a simple sh ip arp Core1 sh ip arp The leftmost six hexadecimal digits of the address correspond to a manufacturer's unique identifier, while the rightmost six digits correspond to the serial number of the network interface card NIC. MAC vs IP Address Relationship Initially it might seem that IP addresses and MAC addresses are redundant because both are unique identifiers of networked devices, but they actually serve different purposes, and are visible in very different ways.
MAC addresses are typically used only to direct packets from one device to the next device as data travels on a network. While when your computer wants to send a packet to some IP address x. The MAC address just gets the data packet to the next device but the IP address is responsible for getting it to the ultimate destination. Switches are unlike hubs or repeaters. A hub simply rebroadcasts every signal on every port to every other port, which while inefficient and slow is easy to create.

A switch, on the other hand, intelligently directs traffic between systems by routing packets only to their proper destination. MAC addresses need to be unique or at least highly unlikely to be repeated for switches to identify different ports and devices, which is why manually setting a MAC address can have unexpected consequences in a switched network. When forwarding a frame, the switch first looks up the MAC address table by the destination MAC address of the frame for the outgoing port.
If the outgoing port is found, the frame is forwarded rather than broadcast, so broadcasts are reduced. In the next packet,I receive the response from If I wanted to, I could then send the same request to Here's the problem with this whole thing.
