docsMcastDefGrpSvcClassDef

Module: DOCS-MCAST-MIB

OID (symbolic): DOCS-MCAST-MIB::docsMcastDefGrpSvcClassDef

OID (numeric): 1.3.6.1.4.1.4491.2.1.18.1.6.1

Node type: OBJECT-TYPE

Type: SnmpAdminString

Access: read-write

Description: This attribute references an instance of the SNMP table docsIetfQosServiceClassName object. This attribute is used to expand the QoS parameter Set of QoS for multicast sessions that uses a default QoS policy. The CMTS persists all instances of this attribute across reinitializations.

What is docsMcastDefGrpSvcClassDef?

Names the default DOCSIS Service Class applied to multicast sessions that don't match any more specific QoS rule; this setting persists across CMTS reboots so the fallback QoS policy survives reinitialization.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.4491.2.1.18.1.6.1
snmpwalk -v2c -c public <target> DOCS-MCAST-MIB::docsMcastDefGrpSvcClassDef

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.4491.2.1.18.1.6.1.1
snmpget -v2c -c public <target> DOCS-MCAST-MIB::docsMcastDefGrpSvcClassDef.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.4491.2.1.18.1.6.1.1 s <value>
