Description: Displays the peer server root dispersion.
What is usdNtpPeerRootDispersion?
This peer's own reported maximum error relative to the primary reference source at the root of its synchronization subnet, in seconds; only positive values are possible. Comparing this across peers helps identify which one sits on the most accurate synchronization path.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.4874.2.2.56.2.4.2.1.12 snmpwalk -v2c -c public <target> Unisphere-Data-System-Clock-MIB::usdNtpPeerRootDispersion
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.4874.2.2.56.2.4.2.1.12.1 snmpget -v2c -c public <target> Unisphere-Data-System-Clock-MIB::usdNtpPeerRootDispersion.1
