TACACS+

Terminal Access Controller Access Control System (TACACS) is a security protocol that provides centralized validation of users who are attempting to gain access to a router or NAS. TACACS+, a more recent version of the original TACACS protocol, provides separate authentication, authorization, and accounting (AAA) services.


Note

  1. RPD can configure 8 TACACS servers at the most. All configured servers use the same secret key.

  2. If multiple TACACS servers are configured, RPD will try to connect TACACS server in the order in which the servers are configured until the connection is established successfully.

  3. RPD and TACACS server must use same address family.

Configuring TACACS+

To enable TACACS+, user needs to setup a TACACS server with secret key configured. Then add this TACACS server's IPv4/IPv6 address and key to RPD configuration. 

R-PHY(config)#tacacs add-server 10.0.0.113 
Server '10.0.0.113' is configured on RPD successfully.

R-PHY(config)#tacacs add-key
Please add a secret key:
Please re-enter your secret key:
Add secret key successfully.

User can also delete server and change the secret key.

R-PHY(config)#tacacs delete-server 10.0.0.112
Delete server '10.0.0.112' successfully.

R-PHY(config)#tacacs change-key        
Please change secret key:
Please re-enter your secret key:
Change secret key successfully.

Displaying TACACS+ Configuration

To display the configured TACACS server, use the show tacacs-server command as shown in the following example: 

R-PHY#show tacacs-server 
TACACS server configured:
10.0.0.113
