SyncServer S600/S650 version 3.2.2 is now released!

Summary of Features


  • PTR12145: To improve security, added additional validation of user input for login banner contents.
  • PTR12146: To improve security, error messages for the password recovery mechanism do not give details on what the user entered incorrectly.
  • PTR12147: To improve security, disabled web browser auto-complete for password on login page.

Resolved Issues

  • KXX-1417: Removed extra characters that were incorrectly added to E1 SSM values.
  • KXX-1423: Corrected issue where several settings were not saved to non-volatile memory or to a configuration backup file. These settings include the J1 IRIG-B setting for the fiber input module, J3 IRIG-B setting for fiber output module, T1 isolated pulse and 2.048MHz square wave output for the E1/T1 timing I/O module.
  • KXX-1431: The SNMP ptpClientAdd and ptpClientDrop objects are now correct in the MIB file. The older SNMP MIB 201811130326Z version had these two objects reversed.
  • KXX-1439: The output phase offset range was corrected for the timing modules.
  • KXX-1442: With the telecom timing module, the J7 icon is now correctly displayed on the input control page after modifying the E1/T1 configuration on the web slot configuration page. In the 3.1 release, it would disappear after modification of the configuration.
  • KXX-1494: Corrected NTPd association display issue when IPv4 address had 15 characters. The data from two entries was combined and incorrect information was displayed in the fields.
  • KXX-1495: To improve security, support for 3DES ciphers was removed in revision 3.1. A side effect was that some web browsers would not connect if the SyncServer HTTPS web server configuration was set to TLS 1.1 with SSL_HIGH_ENCRYPTION. This has now been corrected by always supporting both TLS 1.1 and 1.2. Note that IE11 browser with advanced options set to TLS 1.1-only will still not connect if the SyncServer cipher suite is set to SSL_HIGH_ENCRYPTION.
  • PTR12126: For S650i chassis, input control and status now work correctly for a timing module in slot B.
  • PTR12152: Correctly add leading zeroes to latitude and longitude as required by NMEA-0183 for NMEA-format of TOD output.

Known Issues

Known issues have workarounds or are slated to be fixed in an upcoming release. Generally they are not deemed severe enough to postpone the availability of the release being documented in the System Release Notice.

  • KXX-603: If DHCP has been used to obtain an IP address for a LAN port, the SyncServer S6x0 will not attempt to obtain a new address from a new DHCP server until the DHCP lease expires, even if the old DHCP server is no longer reachable.
  • KXX-844: IPv6 interfaces only allow configuration of the prefix value to 64 in DHCP mode.
    Workaround: None
  • KXX-1129: System user interface will be slow when the unit is heavily loaded processing NTP/PTP traffic.
    Workaround: Be patient or reduce load. Priority is given to servicing time requests.
  • KXX-1395: If the Event Time feature is being used, if a signal with a frequency less than 1 Hz is connected to J1 of a Timing I/O module, then the unit will create LOS (loss of signal) set and clear log entries.
    Workaround: On the “Admin->Alarms” web page, clear the “Write Log” checkbox for the J1 input LOS alarm.
  • KXX-1399: System may prematurely report that it is locked to an NTP input before NTP was fully locked and had set the system time.
    Workaround: Wait until NTP leap indicator shows the system is synchronized (value is not 11).
  • KXX-1404: The Timing I/O Module digital outputs may glitch when the output is first squelched. They also may glitch when the squelch configuration is changed.
    Workaround: If possible, configure receiving device to be tolerant of a glitch when signal is squelched off.
  • KXX-1407: PTP power profile packets in VLAN mode on 10G Ethernet ports have a timestamp inaccuracy of 60ns for sync packets and 120ns for peer-delay packets.
    Workaround: Use a different PTP profile or don’t use VLAN with power profile.
  • KXX-1409: If PTP power profile is used on one port, with NTPr or other PTP profiles as a grandmaster on another port, then some packets will be dropped on the NTPr or non-power profile packet streams.
    Workaround: Do not use PTP power profile simultaneously with NTPr or other PTP profiles (grandmaster).
  • KXX-1424: Optical ports on fiber output module will continue to generate output signal even when squelched or turned off.
  • KXX-1485: IPv4 addresses with values of 100 to 109 in the first octet (for example will not be accepted for the RADIUS/TACACS+/LDAP server IP address. This will be corrected in a future release.


  • The LAN1 interface should not be configured with the same address as one of the other Ethernet ports. If this is done, then network access could be lost to the LAN1 management interface. Each port should be configured on a separate subnet.
  • Serial port settings on the DB9 interface are 115,200 baud, 8N1, Flow Control=None.
  • If using a gateway, then all IP interfaces should be configured with the proper gateway IP address and subnet mask. If a gateway address is programmed on LAN1, then the gateway/router must be present and reachable for the port to operate normally.
  • For SNMPv3 traps, both a user and a trapuser need to be configured identically, depending on the SNMP trap manager. In addition, the SNMP manager should use the specified user/trapuser to connect to the SyncServer S6x0. This will ensure that a SNMPv3 trap will be successfully received by the manager using the corresponding trapuser username.
  • If the browser is displaying a busy indicator, then please wait until the previous action is complete before starting another action. Depending on the browser used, the web page responsiveness will vary due to the use of the encryption cipher suite used in the S600/S650. Microchip recommends using the Google Chrome browser.
