Module: DOCS-IETF-QOS-MIB

OID (symbolic): DOCS-IETF-QOS-MIB::docsIetfQosServiceFlowPrimary

OID (numeric): 1.3.6.1.2.1.127.1.3.1.4

Node type: OBJECT-TYPE

Type: TruthValue

Access: read-only

Description: Object reflects whether Service Flow is the primary or a secondary Service Flow.

A primary Service Flow is the default Service Flow for otherwise unclassified traffic and all MAC messages.

What is docsIetfQosServiceFlowPrimary?

True if this is the primary service flow -- the default flow that carries otherwise-unclassified traffic and all MAC management messages -- and false for any secondary flow. Every cable modem has exactly one primary flow per direction, so this field is key to distinguishing 'the default path' from special-purpose flows like a dedicated VoIP flow.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.127.1.3.1.4
snmpwalk -v2c -c public <target> DOCS-IETF-QOS-MIB::docsIetfQosServiceFlowPrimary

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.127.1.3.1.4.1
snmpget -v2c -c public <target> DOCS-IETF-QOS-MIB::docsIetfQosServiceFlowPrimary.1
