The Cisco Nexus 5000 Series supports both the RADIUS and TACACS+ protocols. It also supports authentication, 

authorization, and accounting (AAA) services to verify the identity of, grant access to, and track the actions of 

engineers who manage the Cisco Nexus 5000 Series fabric.  

The TACACS+ or RADIUS server authenticates the user and returns to the switch the correct role in which the user 

should be placed. The user will then be limited to the functions and features contained in that role. 

The TACACS+ feature is disabled by default. To enable TACACS+ from the CLI, enter: 

switch# config terminal 

switch(config)# feature tacacs+ 

switch(config)# end 

 

To enable the feature through the GUI, follow these steps: 

1. 

In the Device Manager, choose Admin > Feature Control. 

 

 

2. 

In the Feature Control dialog box that appears, select TACACS and choose Action > enable to enable the 

TACACS+ feature.
