Hi,

 

You can try to start the TMM interfaces and see if you can achieve synchronization with NTP servers.

 

So until here for troubleshooting purpose:

 

  1. Configure/Check the System --> Platform with the IP/netmask/Gateway of Mgmt Interface.
  2. Configure/Check the Timezone (System --> Platform).
  3. Set via console/ssh the clock with date command.
  4. Configure DNS Servers.
  5. Configure multiple Public NTP Servers.
  6. Configure VLAN/SELF-IP/Route in the TMM interfaces.
  7. Restart your BIG-IP.
  8. Wait for Sync and check with ntpq -np
