Is HWTACACS compatible with TACACS+

HWTACACS and the TACACS+ protocols of other vendors support authentication, authorization, and accounting. HWTACACS and TACACS+ are identical in authentication process and implementation mechanism. That is, they are compatible with each other at the protocol layer. For example, a device running HWTACACS can communicate with a Cisco server (such as ACS); however, HWTACACS may not be compatible with Cisco extended attributes because different vendors define different fields and meanings for extended attributes.
