ntpCommonDSCPValue
Module: SYMMNTP
OID (symbolic): SYMMNTP::ntpCommonDSCPValue
OID (numeric): 1.3.6.1.4.1.9070.1.2.5.1.2.2.1.1.5
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-write
Description: DSCP value for PTP packets leaving this port. Range is 0-63, and default value is 0.
What is ntpCommonDSCPValue?
This read-write object sets the DSCP value applied to this port's outgoing time-sync packets when ntpCommonDSCP is enabled, ranging from 0 to 63 with a default of 0; the source description refers to it as being for PTP packets, though it sits within the NTP configuration table. Admins set it to match their network's QoS policy for time-sensitive traffic, ensuring NTP packets get consistent priority treatment alongside other latency-sensitive flows. Setting ntpCommonDSCPValue to 46 would mark this port's time-sync packets with an expedited-forwarding DSCP value, once ntpCommonDSCP is enabled.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9070.1.2.5.1.2.2.1.1.5 snmpwalk -v2c -c public <target> SYMMNTP::ntpCommonDSCPValue
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.9070.1.2.5.1.2.2.1.1.5.1 snmpget -v2c -c public <target> SYMMNTP::ntpCommonDSCPValue.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.9070.1.2.5.1.2.2.1.1.5.1 i <value>
