Is HWTACACS supported by S series switches compatible with TACACS+

Both HWTACACS supported by Huawei S series switches (except S1700 switches) and TACACS+ supported by devices from other vendors provide authentication, authorization, and accounting functions, and use the same authentication process and implementation. That is, they are compatible with each other at the protocol layer. For example, a switch 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.
