usdNtpSysClockRootDispersion
Module: Unisphere-Data-System-Clock-MIB
OID (symbolic): Unisphere-Data-System-Clock-MIB::usdNtpSysClockRootDispersion
OID (numeric): 1.3.6.1.4.1.4874.2.2.56.2.1.5
Node type: OBJECT-TYPE
Type: UsdNtpClockUnsignedTime
Access: read-only
Description: This indicates the maximum error relative to the primary reference source at the root of the synchronization subnet, in seconds. Only positive values greater than zero are possible.
What is usdNtpSysClockRootDispersion?
The maximum estimated error, in seconds, relative to the primary reference source at the root of the synchronization subnet; only positive values are possible. A growing root dispersion indicates the accuracy of the whole synchronization chain (not just this device) is degrading.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.4874.2.2.56.2.1.5 snmpwalk -v2c -c public <target> Unisphere-Data-System-Clock-MIB::usdNtpSysClockRootDispersion
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.4874.2.2.56.2.1.5.1 snmpget -v2c -c public <target> Unisphere-Data-System-Clock-MIB::usdNtpSysClockRootDispersion.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> usdNtpSysClockRootDispersion.1
