Work item tracking

• Microsoft ADO: 26156377

How I did it

Setup TACACS server on PTF device and bind to port 49. Because one test bed may run test case in parallel with multiple DUT: For none TACACS test case, run test case with new TACACS server on port 49. For TACACS test case, run test case with old TACACS server on port 59. Force user login with TACACS account, account name is 'admin' password is the value in 'ansible_altpasswords' variable or 'ansible_altpassword' variable.

How to verify it

Pass all test case.
