Terminal Access Controller Access-Control System Plus (TACACS+) is an AAA server protocol that uses a centralized authentication server and multiple network access servers or clients. With TACACS+ support, management of devices seamlessly integrates into network fabric environments. After a device is configured to use TACACS+, it becomes a TACACS+ client.
The NPB application uses the TACACS+ server for authentication and accounting. You can access the device through SSH. The device goes through the same TACACS+ authentication process with either access method. Both IPv4 and IPv6 addresses are supported.
