  • Page 27  STATUS - GPS Bad Geometry: The geometry of the tracked satellites is unsatisfactory for a position solu- tion. Propagate Mode: A position estimation mode used in highly dynamic environments. 2d Solution: The receiver is able to perform position fixes for latitude and longitude but does not have enough satellites for altitude.

  • Page 28: Warning:gpspositionandaltitude

     Web Interface Status: "Current" means that the receiver is using the GPS signal in its timing solution. "Tracked" means the receiver is tracking the signal, but isn't using it in the timing solution. WARNING:GPSPositionandAltitude GPS position and altitude are for timing purposes only. They are not intended for navigation or other critical applications.
  • Page 29  STATUS - NTP basis. In this mode the identity of the peer need not be known in advance, since the asso- ciation with its state variables is created only when an NTP message arrives. Furthermore, the state storage can be reused when the peer becomes unreachable or is operating at a higher stratum level and thus ineligible as a synchronization source.
  • Page 30  Web Interface stratum 1 when the Hardware Clock (stratum 0) is synchronized to an input reference, in holdover mode, or in freerun mode. stratum 2 through 15 when it is synchronized to a remote NTP server. stratum 16 when it is unsynchronized, indicating that it is searching for a valid source of timing information.

  • Page 31: Status - Ptp

    STATUS - PTP jitter: Jitter (also called timing jitter) refers to short-term variations in frequency with com- ponents greater than 10 Hz. stability: Stability refers to how well the SyncServer can maintain a constant frequency over time. It is usually affected by aging, environment changes, etc. The value is expressed units of parts per million (ppm).

Usage: These icons summarize information about the port: (Checkmark): The user has changed the configuration, but hasn't clicked the APPLY button at the bottom of the page yet. (Management Port): This network port is configured as the management port (web interface, SNMP, email, DNS).
  • Page 34 In that case, the NTP clients would have to use an alternate NTP source or become unsynchronized. For this reason, Microsemi recommends using static IP addresses, only using DHCP for convenience during temporary installations.

  • Page 35: Network - Snmp

    Sometimes the network link between the port and its link partner may be lost due to changing of the speed and duplex settings. Microsemi recommends using the Auto setting. Side Effects Applying changes to the Ethernet port configuration restarts the NTP and xinetd daemons (services).

  • Page 39: Ntp - Sysinfo

     NTP - Sysinfo NTP - Sysinfo NTPDaemonStatus This page displays the status of the NTP daemon. Many of the fields below are based on the NTP Packet (on page 198). Also see http://www.ntp.org. system peer: The IP address of the clock source. The source is selected by the NTP dae- mon that is most likely to provide the best timing information based on: stratum, distance, dis- persion and confidence interval.
  • Page 40  Web Interface The Leap Indicator (LI) is a two-bit binary number in the NTP packet header that provides the following information: Advance warning that a leap second adjustment will be made to the UTC timescale at the end of the current day. Leap seconds are events mandated by the world time authority (BIPM) in order to synchronize the UTC time scale with the earth's rotation.
  • Page 41  NTP - Sysinfo uppermost 18 bits of the time stamp fractional component have value, indicating a precision in the microsecond range. root distance (also root delay): This is a measure of the total round trip delay to the root of the synchronization tree.

  • Page 42: Ntp - Assoc

     Web Interface automatically by the initial protocol exchanges between the client and server. This is the broadcast or multicast delay reported by the NTP daemon. The value is always set to 0.004 seconds on the SyncServer. authdelay: When NTP authentication is enabled and performed on outgoing NTP packets, this adds a trivial amount of fixed delay that can be removed based on the authdelay value.

  • Page 43: Ntp - Config

     NTP - Config synchronized. The stratum reported by the SyncServer is incremented by one from its syn- chronizing peer. For example, while synchronized to the Hardware Clock (Stratum 0), the stratum of the SyncServer is one (Stratum 1). Poll: The length of the interval (in seconds) with which the SyncServer polls the remote server, usually starting at 64 seconds and gradually increasing to 1024 seconds.
  • Page 44 NTP Stratum better or equal to that of the SyncServer (client). Often, the NTP server is another Stratum 1 server with a GPS reference that is outside the user's administrative jurisdiction. The NTP servers operated by Microsemi that are part of the factory default configuration are an example of this.
  • Page 45  NTP - Config configured, the two nodes can synchronize with each other in a variety of failure scenarios, such as loss of GPS and Internet connectivity. See system peer mode: symmetric-active under NTP Daemon Status (on page 28). Typical Usage: The user configures NTP associations on two NTP nodes that point to the each other.
  • Page 46  Web Interface association initiates a brief exchange with the server to calibrate the propagation delay. Afterwards, the multicast client association listens to and gets the time from the server messages. This type of association requires authentication on both the server and the clients. See Using NTP Authentication (on page 160). Typical Usage: Multicast client associations can get authenticated time on net- works that have a multicast server.

  • Page 47: Ntp - Md5 Keys

     NTP - MD5 Keys Time to Live: This option is used only with broadcast association. It specifies the time-to-live on broadcast server. Consult with the network administrator to specify a correct value. If this field is left blank, the value of TTL defaults to 127. RESTART Button After changing the NTP configuration, click the RESTART button to put the new configuration into effect.

  • Page 48: Ntp - Autokey

     Web Interface Note: Disregard the "Unable to Open Key File" message while the Current Keys field is empty. RESTART Button After changing the NTP configuration, click the RESTART button to put the new configuration into effect. While the NTP daemon restarts, its services are temporarily unavailable, and it generates the following alarm events: NTP Stratum Change, NTP System Peer Change, NTP Leap Change.

  • Page 49: Ntp - Autokey Client

     NTP - Autokey Client After using the GENERATE button, select the individual key or certificate files and click SAVE AS to download them to a secure location. For the PC scheme, save both the server host key and certificate files to a secure location and install them on the Autokey clients.

  • Page 50: Ntp - Prefs

    The settings on this page determine whether the NTP daemon, once synchronized, can report an unsynchronized state. Note: Microsemi recommends keeping the default Standard NTP Rules setting below. The Override Behavior setting is mostly a "compatibility" setting for custom systems built around legacy TrueTime GPS clocks such as the NTS-200.

  • Page 51: Ptp Option And Time Interval Test

    PTP Option and Time Interval Test Given a pool of NTP associations from which to choose, an NTP client typically syn- chronizes with the best one, and does not require Override Behavior to eliminate poor associations. Given a lack of NTP associations from which to choose, an NTP client may reject a Syn- cServer with better timing accuracy and stability than itself, if Override Behavior is enabled.

    Each reference shows its default priority. For example, "GPS [Default 1]". note: The SyncServer S350i does not include a GPS receiver. Microsemi recommends using the default priorities. The Forced Timing Source setting affects all timing outputs and displays: 997-01520-02 Rev.
  • Page 62 Hardware Clock's Input References. However, a synchronizing NTP asso- ciation can override the FreeRun setting: If the user intends to use UTC time, Microsemi recommends keeping the current NTP configuration. If the user intends to distribute non-UTC time, Microsemi recommends changing the current NTP configuration by deleting all synchronizing NTP associations.

  • Page 63: Timing - Holdover

     TIMING - Holdover TIMING - Holdover Overview The SyncServer uses holdover to continue operating as a stratum 1 NTP server/peer for a period of time if the Input References become unavailable. For example: A SyncServer in a downtown office building gets time from GPS .

  • Page 64: Timing - Sysplex

     Web Interface In Depth Before entering holdover: The Hardware Clock is synchronized to one of the Input References and reports Stratum 0 to the NTP daemon. The NTP daemon is synchronized to the Hardware Clock "reference clock" and reports Stratum 1 to the network. The Hardware Clock enters holdover when the Input Reference becomes unavailable and no other Input References are available.
  • Page 65  TIMING - Sysplex Autostart: Yes: The Sysplex Out connector automatically outputs the time of day after system star- tup. The user cannot stop or restart the output by entering the "C" or "R" commands. No: The user starts or stops the Sysplex output by sending the following characters to the Sysplex Out connector: "C"...
  • Page 66 The third state is "F", the Flywheel Quality Character. The Hardware Clock has no Input References and Holdover has expired. (On the SyncServer S300 and S350, if a syn- chronizing NTP association is present, the Hardware Clock is synchronized to the NTP daemon.)

Using Redundant Ethernet Ports AboutRedundantEthernetPorts The SyncServer's LAN2 and LAN3 network ports can be bonded together as a single, phys- ically redundant, Ethernet connection with a single IP address. Bonding can be used to reduce the Ethernet connection's susceptibility to a single-point failure.

    0.875ms/hr * 3 hrs or 2.625 milliseconds. If your SyncServer has a Rubidium oscillator, the time error would be 0.001ms/hr * 3 hrs or 0.003 milliseconds. Note: To minimize the accumulated time error during outages, Microsemi recommends pur- chasing SyncServer with the Rubidium oscillator option. A SyncServer equipped with a Rubidium oscillator can maintain time to better than one millisecond accuracy to UTC with GPS satellite outages of one month.

Leap Indicator The Leap Indicator (LI) is a two-bit binary number in the NTP packet header that provides the following information:...

  • Page 198: Ntp Daemon

     Glossary NTP Daemon The Network Time Protocol (NTP) Daemon (a.k.a. "ntpd") listens for and responds to requests from NTP clients. It also sends NTP requests to each of the NTP Associations and qualifies each one. It synchronizes with the best NTP association and makes that time avail- able to the See the NTP - Config (on page 43) topics for more information.
