Object

scalar SNMPv2-TCDisplayString

This is an ASCII string identifying the synchronization source for this
NTP server. It is one of CDMA, an IP address of a stratum 1 server, 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 an IP
address, then the server is operating as a stratum 2 server synchronized to
the network connected stratum 1 server whose IP address is shown.

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 cntpSyncSource if it is CDMA. Otherwise
it will be set to either an IP address or 0.0.0.0 (NONE).

How SNMP and these commands work

Scalars have one instance, identified by the .0 suffix.

Read the scalar instance

/usr/bin/snmpget -v2c -c '<community>' -Pud -Ir -OQUv -m 'SONOMA-MIB' -M '/opt/observium/mibs/endrun:/opt/observium/mibs/rfc:/opt/observium/mibs/net-snmp' 'udp:<hostname>:161' 'SONOMA-MIB::cntpSyncSource.0'

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.
