Tacacs configuration not working

Hi Community, I am having some difficulty making my two Routers (ISR4431 and ISR4451) to work on TACACS.

 

The configs are here:

 

Router# show run | sec aaa

 

aaa new-model

aaa group server tacacs+ ISE-TACACS

server name ISESERVERPAN01

server name ISESERVERPAN02

ip vrf forwarding mgmt-interface

aaa group server radius ISE-RADIUS

server name ISESERVERPAN01

server name ISESERVERPAN02

aaa authentication login default group ISE-TACACS local

aaa authentication dot1x default group ISE-RADIUS

aaa authorization config-commands

aaa authorization exec default group ISE-TACACS local

aaa authorization commands 1 default group ISE-TACACS local

aaa authorization commands 15 default group ISE-TACACS local

aaa authorization network default group ISE-RADIUS

aaa authorization auth-proxy default group ISE-RADIUS

aaa accounting update newinfo periodic 2880

aaa accounting dot1x default start-stop group ISE-RADIUS

aaa accounting exec default start-stop group tacacs+

aaa accounting commands 1 default start-stop group ISE-TACACS

aaa accounting commands 15 default start-stop group ISE-TACACS

aaa session-id common

 

Router# show run | sec tacacs

 

aaa group server tacacs+ ISE-TACACS

server name ISESERVERPAN02

server name ISESERVERPAN01

ip vrf forwarding mgmt-interface

aaa accounting exec default start-stop group tacacs+

ip tacacs source-interface GigabitEthernet0/0/3

tacacs server ISESERVERPAN01

address ipv4 10.10.10.10

key 7 1234567890987654321

tacacs server ISESERVERPAN02

address ipv4 10.10.10.11

key 7 1234567890987654321

 

 

 

The devices was added to ISE devices with these config

 

TACACS Authentication Settings
>Shared Secret = 1234567890987654321

>Enable Single Connection Mode = Unchecked and Radio Button is on Legacy Cisco Device

 

I tried to play on this section but still to no avail. I even don't get any logs for my account when I checked on TACACS Live Logs.

 

Take note that all other devices that we have are working. These Routers are the only devices that we cannot add to TACACS.

Hi there,

Can you ping the ISE servers form the routers via the mgmt-interface VRF?

 

What is the output of sh ip route vrf mgmt-interface

 

How come the RADIUS connection isn't being sourced from the mgmt-interface VRF?

 

What is the output of sh tacacs ?

 

cheers,

Seb.
