"The Packet Design Route Explorer (REX) appliance can be configured to make use of external authentication protocols such as TACACS+ and Radius (in addition to the default local authentication capability provided out of the box) This Holonomix AppNote describes how to enable TACACS+ authentication to a CiscoSecure ACS server"
(1) On the Packet Design REX Administration: User Administration screen you will need to define the TACACS+ Server and Shared Secret (selecting the Show Shared Secret button will show the entry in clear text – useful for validating you have entered it correctly). Click on Update to apply the change.

(a) Add Interface Definitions for protocols:
(b) Extend the Interface Configuration to enable per-user TACACS+/RADIUS Attributes:
(c) Configure the User to enable the appropriate rex-* protocol:
It should now be possible to login to the Packet Design REX appliance using the user credentials that you have just configured in CiscoSecure ACS.
