When adding a TACACS server as a method of applying [AAA](/aaa) on a Cisco device, if the TACACS server is in a different [VRF](/vrf), then you must include that information when you configure the IP address of the TACACS server.

In general, if you want to add a TACACS server from a particular VRF, you can do so using the following commands:

```
Router(config)# tacacs server TACACS-SERVER
Router(config-server-tacacs)# address ipv4 10.0.0.10 vrf MGMT
Router(config-server-tacacs)# key <shared-secret>
Router(config-server-tacacs)# exit
```

Here you can see that the particular VRF on which the server is can be indicated. Here it is indicated as `MGMT`.
