radius vs. TACACS+

Answered Question
Dec 26th, 2007


I see implied comments regarding a difference in architecture between how radius views a NAS vs. how TACACS+ does. Is there anyone who is intimately familiar with call flow of each protocol who can comment on how this is different? Is there a difference in what functional part acts as the authenticator?

I have this problem too.

What so ever be the method of authentication there is no change in the role Authenticator performs. Refer the case study in the link http://cisco.com/en/US/products/hw/univgate/ps501/products_case_study_chapter09186a00800ee06a.html#xtocid3 for more information.
