Hi guys,
I need to setup ISE 2.3 for dot1x, mab and webauth for guest self-registration with Catalyst 2960 switch. Can anyone point me to a good resource/documentation? Many thanks in advanced!

Adding to Ognyan's, it's good to reference Cisco ISE Design & Integration with Cisco Switches
and start with How To: Universal IOS Switch Config for ISE

Thank you guys for links and sorry for the late reply.
Anyway, I have now everything setup and from my search and Cisco's documentation I understood that if I want to authenticate my printer, it is recommended to add the MAC address of the printer in ISE instead of active directory group. Also the CWA redirection is not functioning for wired MAB guest PC.
My goal is to achieve the following:
1. DOT1X for domain computers (which works fine and was pretty easy to setup)
2. MAB for printers, security cams, etc (doen't really matter if I use ISE or active directory for me)
3. Wire MAB for guest PC using CWA. (now this didn't work when I used active directory group for wired/wireless_mab or it might be that my authorization wasn't correctly configured)
My concerns or questions:
1. How many MAC addresses can ISE handle? (what if I have more than 1500 MAC addresses, can I import all into ISE)
My issue:
CWA doens't work for my guest PC using wired_mab. When I try to go to cisco.com from the guest PC it can't redirect me to the portal to guest account registration. Event hough I see that I have obtained an IP, but when I copy the redirect url from my switchport and and register an account from another PC the guest PC is able to connect to the Internet. Now I have to mention that the PC is able to ping cisco.com but it can't access cisco.com, I tried FF, Chrome and even IE, but same issue I even tried IP but it was the same.
I tried to debug ip http all but didn't see ANYTHING in the switch.

I have checked dACL and CWA in the central_webauth profile and VLAN in surf_vlan profile
My dACL is at the moment permit ip any any.
All inputs are welcome and thank you in advanced for stepping by.

If you have plus license you can use logical profiles ,and not manually add every printer or etc.
Second thing ,in mine deployment new switch 3650 default acl on port deny all traffic except permited one . When dot1x come
it take ACl from ISE but not apply it .That is in mine deployment.

What is permitted in your default ACL and what is your dACL? Can you share your authorization policies for wired mab?

That's what i try to explain . I remove ACL from port ,and it take Dacl from ise correctly .I am not use Wired mab for guest,only for wireless. but ofc i can share it .
01-17-2018 03:21 AM
Thank you very much, could you share your Authorization policy as well? I don't think my problem is in authentication, it is in authorization. It might be either wrong or configured or missing something.
