Description: Current status of the primary stratum card. synchronized3(1) stratum is synchronized with accuracy 4.6 x 10e-6 synchronized4(2) stratum is synchronized with accuracy 3.2 x 10e-5 holdover(3) an operating condition of a clock that has lost its controlling input and is using stored data acquired while in normal operation, to control its output freerun(4) an operating condition of the clock whose output signals are internally controlled cardRemoved(5) stratum removed

What is stratumMode?

This OID indicates the current synchronization state and accuracy level of the primary stratum card (stratum 3 synchronized, stratum 4 synchronized, or holdover). You monitor this to ensure the device is maintaining tight clock synchronization; stratum 3 provides nanosecond-level accuracy (4.6 × 10^-6), while stratum 4 is looser (3.2 × 10^-5), and holdover means no external reference. For example, a mode of 1 means synchronized to stratum 3 with high accuracy, 2 means degraded stratum 4 accuracy, and 3 means the device is in holdover and drifting.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.17.7
snmpwalk -v2c -c public <target> ACMIB::stratumMode

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.17.7.1
