IEA031I STP ALERT RECEIVED. STP ALERT CODE = nn
Explanation
This message was received because a change occurred with respect to the external time source for the Coordinated Timing Network (CTN).
In the message text:
- nn
- A hex code which uniquely identifies the STP Alert condition.
A list of these codes is given below.
- Hex
- Code Meaning
- 01
- ETS not in use - an External Time Source (ETS) has not been defined for the Coordinated Time Network (CTN).
- 02
- Dial-out time service is outside of allowable tracking range - the time provide by the ETS differs from Coordinated Server Time (CST) by 60 seconds or more.
- 03
- Dial-out time service within allowable tracking range - the difference between the time provided by the ETS and CST is now less than 60 seconds.
- 04
- Dial-out access failure - the CTN is configured for dial-out access but the console was not able to perform a dial out.
- 05
- Dial-out access successful after having recognized a dial-out access failure.
- 06
- NTP server failure - the CTN is in NTP or PPS mode and the console was not able to access any usable NTP server.
- 07
- NTP server operational - the console is now able to successfully access an NTP server that is at stratum level 1 or greater.
- 08
- NTP servers unsynchronized - the CTN is in NTP or PPS mode with both PPS ports enabled and the NTP-PRT offsets for the ports differ by one second or more.
- 09
- NTP servers synchronized - the CTN is in NTP or PPS mode with both PPS ports enabled and the NTP-PRT offsets for the ports now differ by less than one second.
- 0A
- NTP server switch to non-preferred NTP server- the CTN is in NTP mode with PPS ports disabled and the console has switched to the non-preferred NTP server to provide NTP information to the STP server.
- 0B
- NTP server switch to preferred NTP server- the CTN is in NTP mode with PPS ports disabled and the console has switched to the preferred NTP server to provide NTP information to the STP server.
- 10
- Preferred NTP server outside of allowable tracking range - the time provided by the preferred NTP server differs from Coordinated Server Time (CST) by 60 seconds or more.
- 11
- Preferred NTP server within allowable tracking range - the difference between the time provided by the preferred NTP server and CST is now less than 60 seconds.
- 12
- Preferred NTP server stratum level increase - the stratum level of the preferred NTP server has increased (e.g., from stratum level 2 to stratum level 3).
- 13
- Preferred NTP server stratum level decrease - the stratum level of the preferred NTP server has decreased (e.g., from stratum level 3 to stratum level 2).
- 14
- Preferred NTP server inaccessible - the preferred NTP server has transitioned from the accessible state to the inaccessible state.
- 15
- Preferred NTP server accessible- the preferred NTP server has transitioned from the inaccessible state to the accessible state
- 16
- Preferred NTP server stratum error - the preferred NTP server has reported a stratum level of 0 or an invalid stratum level.
- 17
- Preferred NTP server stratum valid - the preferred NTP server has now reported a valid stratum level.
- 18
- Preferred NTP server reference identifier (REFID) change - the REFID for the preferred NTP server has changed.
- 20
- Non-preferred NTP server outside of allowable tracking range - the time provided by the non-preferred NTP server differs from Coordinated Server Time (CST) by 60 seconds or more.
- 21
- Non-preferred NTP server within allowable tracking range - the difference between the time provided by the non-preferred NTP server and CST is now less than 60 seconds.
- 22
- Non-preferred NTP server stratum level increase - the stratum level of the non-preferred NTP server has increased (for example, from stratum level 2 to stratum level 3).
- 23
- Non-preferred NTP server stratum level decrease - the stratum level of the non-preferred NTP server has decreased (for example, from stratum level 3 to stratum level 2).
- 24
- Non-preferred NTP server inaccessible - the non-preferred NTP server has transitioned from the accessible state to the inaccessible state.
- 25
- Non-preferred NTP server accessible- the non-preferred NTP server has transitioned from the inaccessible state to the accessible state
- 26
- Non-preferred NTP server stratum error - the non-preferred NTP server has reported a stratum level of 0 or an invalid stratum level.
- 27
- Non-preferred NTP server stratum valid - the non-preferred NTP server has now reported a valid stratum level.
- 28
- Non-preferred NTP server reference identifier (REFID) change - the REFID for the non-preferred NTP server has changed.
- 81
- Switch to non-preferred Pulse Per Second (PPS) port - the STP facility has switched to the PPS port specified as the non preferred PPS port. This alert is sent by both the active and inactive stratum-1 servers.
- 82
- Switch to preferred PPS port - the STP facility has switched to the PPS port specified as the preferred PPS port. This alert is sent by both the active and inactive stratum-1 servers.
- 83
- PRT source ID change - the PRT source ID for the CTN has changed. The alert is sent by all servers when the PRT source ID for the CTN changes.
- 84
- No PPS Signal - the STP facility no longer has access to a PPS signal.
System action
The system continues processing.
Operator response
Notify the System Programmer. The same event might occur on all images in the Coordinated Timing Network (CTN).
System programmer response
Based upon the alert code from the message, determine what condition change caused the message. If appropriate to your installation, correct the condition. For more details on the alert code conditions, see Server Time Protocol Implementation Guide, SG24-7281.
