juniNtpTimeSynUp

Module: Juniper-System-Clock-MIB

OID (symbolic): Juniper-System-Clock-MIB::juniNtpTimeSynUp

OID (numeric): 1.3.6.1.4.1.4874.2.2.56.2.0.3

Node type: NOTIFICATION-TYPE

Description: This trap indicates that some kind of time synchronization has started. This trap will be generated at the start of time synchronization with the configured time servers irrespective of whether time synchronization is done with all the configured time servers or any one of them (there may be reachability or other problems) when NTP is enabled on the router.

Examples

Send this trap to an SNMP manager — replace <manager> with the IP or hostname of your monitoring server (SNMPv2c):

snmptrap -v2c -c public <manager> '' Juniper-System-Clock-MIB::juniNtpTimeSynUp
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.4874.2.2.56.2.0.3

Listen for incoming traps on the manager host (-f keeps it in the foreground, -Lo prints to stdout — useful for testing):

snmptrapd -f -Lo -c /dev/null authCommunity log public

Example snmptrapd log entry:

zoo11-linux.zoo [UDP: [192.168.30.111]:59608->[192.168.30.10]:162]:
  DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (119446232) 13 days, 19:47:42.32
  SNMPv2-MIB::snmpTrapOID.0 = OID: Juniper-System-Clock-MIB::juniNtpTimeSynUp

Start monitoring Juniper Networks E-series router (system clock/timezone/NTP) with a free 30-day trial of IPNetwork Monitor. Create custom SNMP monitor using the Juniper-System-Clock-MIB::juniNtpTimeSynUp OID value, configure state conditions and alerts, and monitor any Juniper Networks E-series router (system clock/timezone/NTP) from a single console.
