RAP's coming in “default” ap-group 

Mar 29, 2017 02:06 AM

Problem:

RAP's coming in “default” ap-group even when they have another ap-group defined in the RAP-Whitelist



Diagnostics:

 

The reason being, the mac-address of the RAP would be its common name.

Thus, when we do certificate-based authentication the mac-address of the RAP would be used for authentication against the aaa server.

Hence when that knob is disabled the validation would not happen against the aaa server and thus the RAP falls back to the "default" ap-group.

 



Solution

 

The only instance when a certificate based RAP would come up in the "default" ap-group even when its whitelisted to another ap-group is when the "Check certificate common name against AAA server" is disabled (default: enabled) in the "default-iap" or in the "default-rap" L3 authentication profile - The RAP would come up in the "default" ap-group.
