cntpSyncSource

Module: TEMPUSLXUNISON-MIB

OID (symbolic): TEMPUSLXUNISON-MIB::cntpSyncSource

OID (numeric): 1.3.6.1.4.1.13827.5.0.8

Node type: OBJECT-TYPE

Type: DisplayString

Access: read-only

Description: 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).

What is cntpSyncSource?

ASCII string naming what the NTP daemon is currently synchronized to: CDMA, the IP address of an upstream stratum 1 server, or NONE if unsynchronized; check this alongside cntpStratum when troubleshooting why clients report bad time.

Examples
