## Symptoms

- * On SSH screen: After entering the password for TACACS+ non-local user, screen disappears.

* Packet Capture shows a FIN-ACK packet from VSX to TACACS server.

* No drop is shown in kernel debug, since policy is set to allow port 49.

* SmartLog shows "Accept" logs.

* /var/log/messages is showing similiar logs:

  `  
  `
  [Date Time] VSX clish[PID]: User ABC logged out from CLI shell
  `

* On a working machine with TACACS, the following log is seen:

  `
  [Date Time] VSX clish[PID]: User ABC logged in with ReadWrite permission
