NTP over Management VRF Limitations

Be aware of the following limitations before implementing NTP over Management VRF.

  • The communication channel between the NTP client and the server is through the In-Band data port only. An Out-Of-Band (OOB) management port is not supported.
  • One external NTP server must exist to synchronize an NTP client with an NTP server.
  • If you configure NTP in a VRF, ensure that the NTP server and clients can reach each other through the configured VRFs.
  • A source interface must be configured to support the management VRF.
  • The management VRF for NTP broadcast clients is supported only on one interface, using the management source-interface protocol ntp command, because the outgoing port is determined by the routing table.
  • The management VRF for peers is supported only on “symmetric active” (not "symmetric passive") NTP association modes because the management VRF is related to the NTP management source-interface protocol ntp command.
