DNOS-TIMEZONE-PRIVATE-MIB

Description: Controls time zone settings and daylight saving time behavior on Dell DNOS network devices.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

DNOS-TIMEZONE-PRIVATE-MIB is a Broadcom-authored private MIB used within Dell's DNOS (Dell Networking Operating System) for configuring the system clock's time zone and daylight saving time (summer time) behavior on Dell networking devices. It exposes configuration objects for the system time source, time zone offset and acronym, summer-time mode, and detailed recurring DST start/end rules covering week, day, month, and time of day. While primarily a configuration MIB, it supports monitoring the device's software/system status indirectly: the time source and summer-time state objects let an admin confirm the switch is deriving its clock from the intended source (e.g., NTP vs. local) and whether DST is currently active, both important for correlating event/log timestamps during fault diagnosis. As a Broadcom-authored MIB used across DNOS-based platforms, it is tied to Broadcom's switch silicon/software management framework rather than a generic IETF standard. It is typically deployed on Dell EMC Networking switches running DNOS in enterprise data center and campus environments. Engineers can download the DNOS-TIMEZONE-PRIVATE-MIB file directly to load it into their MIB browser.

An admin would check agentSystemTimeSource to confirm the switch is synchronized from the expected authoritative time source, and agentSystemSummerTimeState to verify daylight saving time is correctly applied or not depending on the calendar date. agentTimeZoneMinutesOffset and agentTimeZoneAcronym would be read to confirm the configured time zone matches the site's actual location, catching a misconfigured device whose logs would otherwise show a confusing offset. The agentStRecurringStartingWeek/Day/Month/Time objects and their corresponding ending objects define the exact DST transition rule, useful when validating that a device will correctly switch clocks at the right moment for its region.
