Module: TIME-MIB
OID (symbolic): TIME-MIB::swClockLostOnReboot
OID (numeric): 1.3.6.1.4.1.171.12.10.3
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-only
Description: Indication of whether the system can preserve knowledge of current date and time across a system reboot. A value of 'true' indicates the clock must be reset from some external source each time the system reboots. A value of 'false' indicates the system has the ability to keep time across reboots.
What is swClockLostOnReboot?
This true/false value indicates whether the switch loses its knowledge of the current date and time across a reboot; true means the clock must be reset from an external source (like SNTP) after every reboot, false means the hardware retains time across reboots. Admins check it to know whether they need to configure SNTP or manually reset the clock after every restart of that model. A switch reporting swClockLostOnReboot as true would need SNTP configured so its time is automatically corrected after each reboot rather than reverting to a default.
