Configuring an External TACACS+ Server
Configuring an External TACACS+ Server
The ASA provides support for TACACS+ attributes. TACACS+ separates the functions of
authentication, authorization, and accounting. The protocol supports two types of attributes: mandatory
and optional. Both the server and client must understand a mandatory attribute, and the mandatory
attribute must be applied to the user. An optional attribute may or may not be understood or used.
Note To use TACACS+ attributes, make sure that you have enabled AAA services on the NAS.
Table 1-10 lists supported TACACS+ authorization response attributes for cut-through-proxy
connections. Table 1-11 lists supported TACACS+ accounting attributes.
