TACAS not working - No TACACS packets in TCPDUMP

For the traffic is the interface for the interface for rotations to manage servers to TACACS.

For Example:

sys management-route TACACS-1 {
    gateway 10.24.131.1
    network 192.168.134.206/32 
} 
sys management-route TACACS-2 {
    gateway 10.24.131.1
    network 10.51.10.68/32
}

I had static route entries added for the tacacs server under sys management-route, but it appears that BigIP won't even attempt to use the management interface (I suspect that the management interface is not a part of the logical BigIP network, since it doesn't show up in the list of vlans and interfaces under "network".

The management interface is Out-of-band, you can not see it in the graphical interface.

To identify the correct interface, access via SSH and enter the command "ifconfig" in bash, the management is usually ETH0, check and see if the displayed IP is the same as the one used to access the BIG-IP.

The ideal is to leave a capture running while trying to access the BIG-IP via TACACs, to see what are the IPs of the TACACs, with the command "tmsh list auth tacacs"

Example:

root@(bigip-lb01) (cfg-sync Standalone) (Active) (/ Common) (tmos)  list auth tacacs
auth tacacs system-auth {
    authentication use-all-servers
    debug enabled
    ip protocol
    secret $M$Ju$LSrECPSSDDDDTfb0HDmgJ2Dj50Q ==
    servers *{10.1.1.230}*
    service ppp
}

Do both captures at the same time.

tcpdump -nni eth0 10.1.1.230 << This for capturing in the management interface

tcpdump -nni 0.0 10.1.1.230 -e << This for capturing at data traffic interfaces

Forward the result after the test.
