These MAC addresses are 48 bits or 6 bytes long, so they are also known as MAC-48 or EUI-48. EUI stands for Extended Unique Identifier. It is written in hexadecimal characters as shown below:

When you connect your server or storage, it will send a Fabric login (FLOGI) request. This FLOGI request serves two purposes: Fibre Channel ID is the WWPN connection to this port from the FLOGI server Exchange buffer credits with the switch To better understand the first function, it is exactly the same if I rewrite it as, “request an IP address for a MAC address from the DHCP server”.
