And then we’ll take a look at the Ethernet frame format. .ut to begin with, a switch is going to make intelligent forwarding decisions based on Mac addresses. Those are the 48 bits burned into the address es of each of our Ethernet clients’ network interface cards. And when the switch sees frames come in, it’s going to take a look at where the frame came from and start constructing a Mac address table. For example, a laptop user wants to talk to the printer , and the switch, let’s pretend, has just booted up. It has not learned any Mac addresses. When this laptop sends a frame into the switch with the allc’s Mac address as the destination, the switch will do a couple of things. It will be noted that the old A ’s Mac address just arrived on gig one. It’s going to make a note of that in the Mac address table. However, it will then duplicate that frame and send it out all ports other than the one it came in on. So it sends a copy to gig two, gig three, and gig fou r. That process is called flooding. The switch is desperately trying to make sure that the frame does make it to its intended destination. And the good news is that it did. It got to the printer. The printer says, “Yep, I’m the OLC’s Mac address,” and it r esponds to the laptop. And when it responds, notice that the switch does not flood that frame because it has learned that the destination Mac address is all AS, and it lives off of gig one. And when it sees that frame come in for the printer, it adds that OC’s Mac address to its Mac address table. So now, when the laptop wants to talk to the printer, it’s going to go directly to the printer. It’s not going to be flooded anymore. Let’s take a look at another example. Let’s say that laptop two with the old B’ s Mac address wants to talk with the server with the old D’s Mac address. Well, when the frame goes into the switch, the switch has not yet learned that the old DSMac address lives off of gig four. So what’s it going to do? Yeah, it’s going to flood it out of gigs one, three, and four to make sure it gets to its intended destination. But the switch is going to make a note that the all - bees Mac address lives off of gig two.
