Okay so I've been trying to figure out exactly what IOS XR has a problem with regarding our internal NTP servers. I was seeing things like this: RP/0/RSP0/CPU0:Oct 31 15:18:37.422 EDT: ntpd[263]: %IP-IP_NTP-5-HP_CONN_LOST : High priority NTP peer connection lost - Stratum 2->3. RP/0/RSP0/CPU0:Oct 31 15:34:14.370 EDT: ntpd[263]: %IP-IP_NTP-5-HP_CONN_RECOVERED : High priority NTP peer connection recovered - Stratum 3->2. RP/0/RSP0/CPU0:Oct 31 16:09:25.511 EDT: ntpd[263]: %IP-IP_NTP-5-SYNC_LOSS : Synchronization lost : 192.168.123.6 : System clock selection failed RP/0/RSP0/CPU0:Oct 31 16:09:25.511 EDT: ntpd[263]: %IP-IP_NTP-5-HP_CONN_LOST : High priority NTP peer connection lost - Stratum 2->3.

RP/0/RSP0/CPU0:Oct 31 22:19:58.036 EDT: ntpd[263]: %IP-IP_NTP-5-HP_CONN_RECOVERED : High priority NTP peer connection recovered - Stratum 3->2.

So I created 5 more NTP servers and configured it to use all 6 of them. It is actually now having sync issues MORE often. I am considering just suppressing the logs for this particular type of log message but before I do that, has anyone ever actually figured out what problem IOS XR has with standards compliant and fully functional NTP servers? Is there a special way that you have to configure ntpd on a linux host to get this to.. stop? _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
