Configurar a autenticação baseada em MAC e o MAC Authentication Bypass (MAB)

Well, what about wired devices? How do we authenticate an authorized wired client? Well, it turns out we could do it right here in the same place. So we could create a couple of more rules. So we can say OK, if we look at wired devices that are using certificates to authenticate , we could just call this rule wired certificate authentication. We can effectively apply the same matching criteria as for wireless. There's no difference whatsoever here.

On the right-hand side, we'll decide where we want to move these devices after authentication and the right policy match. And finally, what about non-.1x capable devices on the wired side? So for example, I have here a Phillips hub that does not support .1x. How can I authenticate a Phillips app? So I could create a label for the Phillips device. The label will be client list. And I'll just say approved Phillips app. And I'll just put the MAC address of that device in. Oh. And you could put a list of MAC addresses. You can put the list of Mac OUIs. And remember that all of these labels that I'm creating in the UI - they're all available through the REST API. So there is always an endless possibility of integration with existing, say, inventory management systems that can just put all the new device MAC addresses in those lists for authentication and authorization.

So we'll just click Create. Create this label. And we'll create a rule. We'll call it approved Phillips devices. And here we are matching on wired devices that are doing MAC address authentication bypass that are part of this client list label. And in this case, we will move them to - well, I don't want to move them to Corp VLAN. That's not what I want. I will create an IoT VLAN. And in our case, that's going to be VLAN 3000. And I'm going to add this to an IoT VLAN. And now, we have our authentication policies configuration done.

OK, so how do we validate, right? So we've connected a couple of clients to the switch. One is a laptop that's doing .1x using certificate. Another one is the Phillips Hue app. That doesn't do any .1x, and just doing MAC authentication. So we could see those two clients are connected.

Let's take a look at the laptop one. So we could click on the port. We see that there is a client with a username flashing up. Let's take a look at the wired client insights. And what we can see here is that the user has been authenticated. You could see the port up and down events from the switch side. We see all the authentication phases, same as we saw in the wireless side. The client trusts the server. The server trusts the client certificate. We get all the metadata here. We then are saying client access is allowed. And voila. We matched the same authentication policy rule. Great. So now, we know that this part is working.

Now, we go to switch back. And let's look at the Philips device. That device is not doing any form of .1x authentication. So let's just take a look at the wired client insights. Yeah, and we are seeing that here the user is authenticated. And there is a client access allowed event here as well. And in this case, the authentication type is Mac address bypass - the MAC address that we've added to the client list. And voila. We are matching the right approved Phillips device rule.
