Description: MICROSENS G6 switch MIB for NTP client configuration, server selection, and time synchronization status.

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.

What Is G6-NTP-MIB?

This is a Microsens private MIB for their Generation 6 (G6) family of managed Ethernet switches, focused on Network Time Protocol (NTP) client configuration and time synchronization. It exposes configuration data such as enabling/disabling NTP, selecting main and backup NTP servers, DHCP-provided server options, sync interval, and trusted server settings, alongside status/display objects for current time, date, and timezone. Rather than physical sensors, its primary monitoring value is verifying software-level time synchronization status on the switch, confirming whether the device's clock is actually syncing to its configured servers and displaying the correct time, which is critical for accurate event and log timestamps. It is a switch-vendor MIB that operates independently but is conceptually related to standard NTP management approaches where present. It is deployed on Microsens G6-series industrial/managed Ethernet switches where accurate time synchronization is needed for logging, security, or protocol correlation. Engineers can download the G6-NTP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in G6-NTP-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Monitoring Examples

An administrator would check ntpEnableNtp and ntpSyncNow to confirm NTP is active and force an immediate resync, then read ntpMainNtpServer and ntpBackupNtpServer to verify the correct time sources are configured. Polling ntpShowTimeDate against a trusted external clock reveals drift or failed synchronization, while ntpSyncInterval shows how frequently the switch checks in. If ntpDhcpProvidesNtpServer is enabled but ntpTrustedServer doesn't match expectations, it could indicate a rogue or misconfigured DHCP-supplied time source.

What Can Be Monitored

OID symbolic	OID numeric	Type	Access	Description
management	1.3.6.1.4.1.3181.10.6.3			Microsens private MIB for Generation 6 Ethernet Switches
ntp	1.3.6.1.4.1.3181.10.6.3.73
INT ntpEnableNtp	1.3.6.1.4.1.3181.10.6.3.73.1	INTEGER	read-write	When enabled the local clock will be synchronized with the time provided by a time server.
STR ntpSyncNow	1.3.6.1.4.1.3181.10.6.3.73.2	DisplayString	read-write	Action command to read time server now and setup the internal clock.
INT ntpDhcpProvidesNtpServer	1.3.6.1.4.1.3181.10.6.3.73.3	INTEGER	read-write	Enable DHCP to automatically retrieve NTP server address(es). When disabled, the locally defined addresses are used instead.
STR ntpMainNtpServer	1.3.6.1.4.1.3181.10.6.3.73.4	DisplayString	read-write	This is the preferred NTP server address. IP address or symbolic name may be used.
STR ntpBackupNtpServer	1.3.6.1.4.1.3181.10.6.3.73.5	DisplayString	read-write	This defines an optional alternate ntp server address. IP address or symbolic name may be used.
INT ntpTrustedServer	1.3.6.1.4.1.3181.10.6.3.73.6	INTEGER	read-write	Some NTP server (Windows) indicate a too large deviation or indicate they are unreliable when they are not externally synchronized. To be able to still use such a server set this option to true.
I32 ntpSyncInterval	1.3.6.1.4.1.3181.10.6.3.73.7	Integer32	read-write	Resynchronization interval (minutes), default once per day.
STR ntpShowTimeDate	1.3.6.1.4.1.3181.10.6.3.73.8	DisplayString	read-write	Show system time and date.
STR ntpListTimeZones	1.3.6.1.4.1.3181.10.6.3.73.9	DisplayString	read-write	Displays a long list of available timezones. Pick the timezone that matches your location and use this name for the time_zone parameter.
STR ntpTimeZone	1.3.6.1.4.1.3181.10.6.3.73.10	DisplayString	read-write	Enter a string exactly as obtained via list_time_zones command. Note that a change of the time zone if only effective after a system reboot.
STR ntpTimeFormat	1.3.6.1.4.1.3181.10.6.3.73.11	DisplayString	read-write	This parameter permits definition of the time format displayed under ntp.local_time. When left blank the default format hrs:min:sec is used. The parameter follows the Linux date command syntax. Please refer to external documentation for details. Use %k:%M for time without seconds. Use %P to add AM/PM where is applies. There are more options.
STR ntpDateFormat	1.3.6.1.4.1.3181.10.6.3.73.12	DisplayString	read-write	This parameter permits definition of the data format displayed under ntp.local_date. When left blank the default format year-month-date is used. The parameter follows the Linux date command syntax. Please refer to external documentation for details. It is also possible to add weekday %A or month %B or week of year %V, etc.
