ciscoBitsClockHoldover
Module: CISCO-BITS-CLOCK-MIB
OID (symbolic): CISCO-BITS-CLOCK-MIB::ciscoBitsClockHoldover
OID (numeric): 1.3.6.1.4.1.9.9.459.0.3
Node type: NOTIFICATION-TYPE
Description: An external clock source is unavailable. The internal clock will operate in holdover mode. The network clock module has stored information about the incoming clock signal, it can faithfully reproduce the lost signal while in holdover mode until a switchover to another clock source occurs.
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-BITS-CLOCK-MIB::ciscoBitsClockHoldover snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.9.9.459.0.3
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]:51364->[192.168.30.10]:162]: DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (464379556) 53 days, 17:56:35.56 SNMPv2-MIB::snmpTrapOID.0 = OID: CISCO-BITS-CLOCK-MIB::ciscoBitsClockHoldover
