show ntp associations [vsx-peer]


Shows the status of the connection to each NTP server. The following information is displayed for each server:

  • Tally code : The first character is the Tally code:
    • (blank): No state information available (e.g. non-responding server)

    • x : Out of tolerance (discarded by intersection algorithm)

    • . : Discarded by table overflow (not used)

    • - : Out of tolerance (discarded by the cluster algorithm)

    • + : Good and a preferred remote peer or server (included by the combine algorithm)

    • # : Good remote peer or server, but not utilized (ready as a backup source)

    • * : Remote peer or server presently used as a primary reference

    • o : PPS peer (when the prefer peer is valid)

  • ID: Server number.
  • NAME: NTP server FQDN/IP address (Only the first 24 characters of the name are displayed).
  • REMOTE: Remote server IP address.
  • REF_ID: Reference ID for the remote server (Can be an IP address).
  • ST: (Stratum) Number of hops between the NTP client and the reference clock.
  • LAST: Time since the last packet was received in seconds unless another unit is indicated.
  • POLL: Interval (in seconds) between NTP poll packets. Maximum (1024) reached as server and client sync.
  • REACH: 8-bit octal number that displays status of the last eight NTP messages (377 = all messages received).
