The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

The Per VRF for TACACS+ Servers feature allows per VRF AAA to be configured on TACACS+ servers. Prior to Cisco IOS Release 12.3(7)T, this functionality was available only on RADIUS servers.
The initial steps in this procedure are used to configure AAA and a server group, create a VRF routing table, and configure an interface. Steps 10 through 13 are used to configure the per VRF on a TACACS+ server feature:
To verify the per VRF TACACS+ configuration, perform the following steps:
Note |
The debug commands may be used in any order. |
The following output example shows that the group server tacacs1 is configured for per VRF AAA services:
aaa group server tacacs+ tacacs1 server-private 10.1.1.1 port 19 key cisco ip vrf forwarding cisco ip tacacs source-interface Loopback0 ip vrf cisco rd 100:1 interface Loopback0 ip address 10.0.0.2 255.0.0.0 ip vrf forwarding cisco
