gntpSyncSource – ENDRUNTECHNOLOGIES-MIB

Object

scalar SNMPv2-TCDisplayString

This is an ASCII string identifying the synchronization source
for this NTP server. It is one of GPS, CPU or NONE. If it is NONE,
then the server is not synchronized, has its Leap Indicator Bits in the Alarm
state and is running at Stratum 16. If it is CPU, then the server is
running on its NTP disciplined CPU clock at Stratum 11.

Check the Stratum, Leap Indicator Bits and Time Figure of Merit for further
information. NTP reply packets from this server will have the reference
identifier field set to gntpSyncSource if it is GPS. Otherwise
it will be set to either 127.127.1.0 (CPU) or 0.0.0.0 (NONE).

Syntax

SNMPv2-TCDisplayString

Source: SNMPv2-TCDisplayString
Base type: OctetString
Display format: 255a

Type Description

Represents textual information taken from the NVT ASCII
          
character set, as defined in pages 4, 10-11 of RFC 854.
          
To summarize RFC 854, the NVT ASCII repertoire specifies:
          
  - the use of character codes 0-127 (decimal)
          
  - the graphics characters (32-126) are interpreted as
    US ASCII
          
  - NUL, LF, CR, BEL, BS, HT, VT and FF have the special
    meanings specified in RFC 854
          
  - the other 25 codes have no standard interpretation
          
  - the sequence 'CR LF' means newline
          
  - the sequence 'CR NUL' means carriage-return
          
  - an 'LF' not preceded by a 'CR' means moving to the
    same column on the next line.
          
  - the sequence 'CR x' for any x other than LF or NUL is
    illegal.  (Note that this also means that a string may
    end with either 'CR LF' or 'CR NUL', but not with CR.)
          
Any object defined using this syntax may not exceed 255
characters in length.
