The Wired MAB(MAC Authentication Bypass) with Cisco ISE 3.0

This is a simple topic but I couldn't see any document related to ISE 3.0 on the web. I won't mince words and will pass my topic.

I will talk with pictures. I created a topology with the Eve-Ng simulation program.

1. Switch configuration:

aaa new-model
aaa authentication dot1x default group radius
aaa authorization network default group radius
aaa accounting dot1x default start-stop group radius

interface Ethernet0/3
 switchport access vlan 10
 switchport mode access
 authentication order dot1x mab
 authentication priority dot1x mab
 authentication port-control auto
 dot1x pae authenticator

radius server RAD2
 address ipv4 auth-port 1812 acct-port 1813
 key cisco123

2. Add network device to ISE:

3. Setup the Allow Protocol:

4. Setting Policy:

This part is important.

We define a policy like below;

Define the policy name and select a condition(Wired-MAB) from the condition studio. Choose the Company-Protocol which is defined before as an Allowed protocol.

Conditons Studio:

Click the arrow and go into Policy:

You will see a few sections below. We only use the authentication and authorization section.

4a. Authentication Policy:

If you want you can choose many conditions.

4b. Authorization Policy:

After defining the authentication and authorization policy, don't forget to save it.

5. Add the Mac address to Endpoint database:

You will see your Mac address on Endpoint then you will add the Mac address to Endpoint like below.

6. Check the Logs:

Click the detail.


You will see the " 5200 Authentication succeeded"

Thanks for Reading.
