Wired WebAuth support in SDA fabric

Hello,

I know that ISE and Cat 9000 switches do support multiple authentication fallback configuration, including WebAuth.

I would like to confirm if wired WebAuth based on ISE DB (eg. wired guest access) is supported in a SDA fabric, and in detail:

1) Can you configure on a wired switch port in a SDA fabric a 3-steps fallback auth method chain such as: 802.1x, then MAB, then WebAuth?

2) Is this fully supported by BU and TAC? Any caveats?

thank you,

Luca

AKAIK you can use WebAuth. The caveat is as of the latest DNAC version 1.3.1.3 engineers cannot create their own authentication template under Design->Authentication Template. The issue here is that the default Cisco templates deploy IBNS service templates with pre-defined configs to your edge nodes within your fabric. The current workaround is to utilize the template editor for any things you wish to modify. I am currently running an SDA fabric where we deploy the default Closed Auth template, but then tweak items via the template editor which in regard to your topic include:
-Modification of dot1x/mab order & priority
-Modification of the default critical auth and voice vlans
-8021x timers
-Modification of the default webauth acl
Via ISE I have setup the default 8021x/mab authz policy to redirect users to a guest modified hotspot portal that essentially has access to VERY little and is a generic splash page with help desk number etc. This works like a charm.
