Goal

This document explains how to check if the IMF has a good NTP sync and if it is properly configured to provide an NTP source for the eagle STP.

Solution

1. To verify NTP sync on IMF, use the following command:
   [root@IMF-1A ~]# ntpq -np
     remote refid st t when poll reach delay offset jitter
   ==============================================================================
   10.172.40.205 .INIT. 16 u - 64 0 0.000 0.000 0.000
   *10.109.3.108 .GPS. 1 u 7 16 377 0.989 -0.482 0.031
   "delay" should be below 10ms, "offset" and "jitter" below 1ms
2. To verify if NTP broadcast are sent over the yellow network, use the following command:
   [root@IMF-1A ~]# tcpdump -i bond0.100 -f 'port 123'
   tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
   listening on bond0.100, link-type EN10MB (Ethernet), capture size 96 bytes
   13:05:42.744688 IP yellow-1b.ntp > yellow-1a.ntp: NTPv4, symmetric active, length 48
   13:05:42.744842 IP yellow-1a.ntp > yellow-1b.ntp: NTPv4, symmetric active, length 48
   13:06:06.176113 IP yellow-1a.ntp > 224.0.1.1.ntp: NTPv4, Broadcast, length 48
   13:06:47.744422 IP yellow-1b.ntp > yellow-1a.ntp: NTPv4, symmetric active, length 48
   13:06:47.744513 IP yellow-1a.ntp > yellow-1b.ntp: NTPv4, symmetric active, length 48
   13:07:10.176623 IP yellow-1a.ntp > 224.0.1.1.ntp: NTPv4, Broadcast, length 48
    The bolded lines have to be present to confirm the NTP broadcast are sent to Eagle STP
