juniNtpTimeServerSynDown

Module: Juniper-System-Clock-MIB

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

OID (numeric): 1.3.6.1.4.1.4874.2.2.56.2.0.6

Node type: NOTIFICATION-TYPE

Description: This trap will be generated to report the time synchronization status of each configured time server on the router when it stops time synchronization with the NTP client for any reasons.

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::juniNtpTimeServerSynDown
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.4874.2.2.56.2.0.6

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]:56407->[192.168.30.10]:162]:
  DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (358031447) 41 days, 10:31:54.47
  SNMPv2-MIB::snmpTrapOID.0 = OID: Juniper-System-Clock-MIB::juniNtpTimeServerSynDown
