This article provides a guideline for troubleshooting the "NTP server not responding" alarm on the BTI7000 Series platform.

 

Refer to the following table to check whether the "NTP server not responding" alarm is visible via each tool/command.

Tools / Commands	Is the "NTP server not responding" alarm is visible?
TL1 command rtrv-alm-all	Yes
TL1 command rtrv-cond-all	Yes
CLI command show alarm all	No
CLI command show condition all	No
ProNX 900 Node Controller	Yes
ProNX Service Manager (PSM)	Yes

 

For users who prefer the command line rather than the Graphical User interface, the TL1 session will show the NTP related alarms.

• Use TL1 commands rtrv-alm-all and rtrv-cond-all when you would like to confirm if the "NTP server not responding" alarm is active on a BTI7000 platform.

• Use the TL1 command rtrv-ntpassoc to check device NTP configurations, and the TL1 command rtrv-ntp to check device NTP status.

See the following example:

 

BTI7000> rtrv-alm-all

   BTI7000 20-03-17 04:04:59
M  100 COMPLD
   "172.27.93.22,NE:MN,SRVR-UNRESPONSIVE,NSA,03-17,03-43-42,NEND,,:\"NTP server not responding.\",,,:,"
;
BTI7000> rtrv-cond-all

   BTI7000 20-03-17 04:05:17
M  100 COMPLD
   "172.27.93.22,NE:MN,SRVR-UNRESPONSIVE,NSA,03-17,03-43-42,NEND,,,\"NTP server not responding.\""
;
BTI7000> rtrv-ntpassoc

   BTI7000 20-03-17 04:02:42
M  100 COMPLD
   "ASSOCIPADDR=172.27.93.22"
;
BTI7000> rtrv-ntp

   BTI7000 20-03-17 04:01:21
M  100 COMPLD
   "POLLPERIOD=01-00,SYNCSTATE=N,STRATUM=0,REFIPADDR=0.0.0.0"
;

 

The CLI session has in its output the NTP configuration but not the NTP related alarms.

See the following example:

 

BTI7000> show ntp
Polling Period                 : 00:01 (HH:MM)
The system is using local date and time.
NTP associations (IP address) in random order
---------------------------------------------
172.27.93.22

BTI7000> show alarm all
BTI7000> show condition all        
BTI7000>

 

The ProNX 900 Node Controller shows the NTP related alarm as shown in the following example:

PSM shows the NTP related alarms as shown in the example below:

While the causes for the "NTP server not responding" alarm are usually either communications between the BTI7000 and the NTP server or NTP server malfunction, the BTI7000 platform does not display the "NTP server not responding" alarm in the show alarm all / show condition all CLI command output, which can cause confusion during troubleshooting.

 

The Command Line Interface (CLI) does not support NTP related alarms and conditions.

 

After confirming that the "NTP server not responding" alarm is active on the device, work with the operator of the NTP server that has displayed the alarm to resolve any issues related to the following factors:

 

• The NTP server at the IP address is not running/ is down.

• The NTP server at the IP address is not responding.

• The NTP communication is blocked by a firewall (NTP server listens to UDP port 123).
