  • Page 74: Ntp Associations

    Before synchronizing, NTP compares the time reported by several network devices and does not synchronize with one that is significantly different, even if it is a stratum 1. Because Cisco NX-OS cannot connect to a radio or atomic clock and act as a stratum 1 server, we recommend that you use the public NTP servers available on the Internet.

  • Page 75: Ntp Multicast Associations

    NTP as a Time Server The Cisco NX-OS device can use NTP to distribute time. Other devices can configure it as a time server. You can also configure the device to act as an authoritative NTP server, enabling it to distribute time even when it is not synchronized to an outside time source.

  • Page 76: Virtualization Support

    Virtualization Support If you are running a Cisco NX-OS Release prior to 5.2, up to one instance of NTP is supported on the entire platform. You must configure NTP in the default virtual device context (VDC), and you are automatically placed in the default VDC unless you specify otherwise.
  • Page 77 • If you configure NTP in a VRF, ensure that the NTP server and peers can reach each other through the configured VRFs. • You must manually distribute NTP authentication keys on the NTP server and Cisco NX-OS devices across the network.

    Cisco NX-OS automatically creates system checkpoints. You can use either a user or system checkpoint to perform a rollback. You can create a checkpoint copy of the current running configuration at any time. Cisco NX-OS saves this checkpoint as an ASCII file which you can use to roll back the running configuration to the checkpoint configuration at a future time.
