What is ctUserDefNumTrafficClass?

This read-only INTEGER, ranging 1 through 8, reports the number of traffic classes (output queues) supported on each port of this device. An admin uses this to know how many distinct priority queues are actually available for mapping traffic. For example, a value of 4 tells the admin only four output queues exist per port, so the eight possible incoming priorities must be consolidated into those four queues via ctTrafClassValue.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.2.12.1.4.2.1.1.1.3
snmpwalk -v2c -c public <target> CT-PRIORITY-QUEUING::ctUserDefNumTrafficClass

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.2.12.1.4.2.1.1.1.3.1
snmpget -v2c -c public <target> CT-PRIORITY-QUEUING::ctUserDefNumTrafficClass.1
