Module: CADANT-CMTS-LAYER2CMTS-MIB

OID (symbolic): CADANT-CMTS-LAYER2CMTS-MIB::cadIfMacDomainCmUdcEnabled

OID (numeric): 1.3.6.1.4.1.4998.1.1.20.1.4.2.1.30

Node type: OBJECT-TYPE

Type: TruthValue

Access: read-write

Description: If set to true, this attribute instructs the CMTS MAC Domain to enable Upstream Drop Classifiers (UDC) for the CMs attempting registration in this MAC Domain.

What is cadIfMacDomainCmUdcEnabled?

This object controls whether the CMTS (Cable Modem Termination System) should enable Upstream Drop Classifiers (UDC) for cable modems attempting to register in a specific MAC Domain. When set to true, UDC functionality is active, allowing the CMTS to classify and manage upstream traffic from modems more effectively. An operator would enable this to improve traffic quality management and enforce QoS policies for cable modem uplink channels.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.4998.1.1.20.1.4.2.1.30
snmpwalk -v2c -c public <target> CADANT-CMTS-LAYER2CMTS-MIB::cadIfMacDomainCmUdcEnabled

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.4998.1.1.20.1.4.2.1.30.1
snmpget -v2c -c public <target> CADANT-CMTS-LAYER2CMTS-MIB::cadIfMacDomainCmUdcEnabled.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.4998.1.1.20.1.4.2.1.30.1 s <value>
