ciscoSystemClockChanged

Module: CISCO-SYSTEM-MIB

OID (symbolic): CISCO-SYSTEM-MIB::ciscoSystemClockChanged

OID (numeric): 1.3.6.1.4.1.9.9.131.2.0.1

Node type: NOTIFICATION-TYPE

Description: A clock changed notification is generated when the current local date and time for the system has been manually changed. The value of csyClockDateAndTime reflects new date and time.

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> '' CISCO-SYSTEM-MIB::ciscoSystemClockChanged
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.9.9.131.2.0.1

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]:56970->[192.168.30.10]:162]:
  DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (413463690) 47 days, 20:30:36.90
  SNMPv2-MIB::snmpTrapOID.0 = OID: CISCO-SYSTEM-MIB::ciscoSystemClockChanged

SNMPv3 example:

snmptrap -v3 -l authPriv -u snmpv3user -a SHA -A "AuthPass1" -x AES -X "PrivPass1" <manager> '' CISCO-SYSTEM-MIB::ciscoSystemClockChanged
