Module: MERIDIAN2-MIB

OID (symbolic): MERIDIAN2-MIB::gntpSyncSource

OID (numeric): 1.3.6.1.4.1.13827.14.1.13

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 GPS, 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 gntpSyncSource if it is GPS. Otherwise it will be set to either an IP address or 0.0.0.0 (NONE).

What is gntpSyncSource?

An ASCII string naming what this NTP server is currently synchronized to: GPS, the IP address of an upstream stratum-1 server it's chained off of, or NONE if it isn't synchronized at all (in which case it also reports stratum 16 and an alarmed leap indicator). This is the field to check first when troubleshooting why a server's clients are getting bad or absent time.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.13827.14.1.13
snmpwalk -v2c -c public <target> MERIDIAN2-MIB::gntpSyncSource

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.13827.14.1.13.1
snmpget -v2c -c public <target> MERIDIAN2-MIB::gntpSyncSource.1

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> gntpSyncSource.1
