Module: TN-QOS-EXT-MIB

OID (symbolic): TN-QOS-EXT-MIB::tnQosExtL2CosIfClassifDefaultClass

OID (numeric): 1.3.6.1.4.1.868.2.5.9.1.2.1.1.1

Node type: OBJECT-TYPE

Type: INTEGER

Description: Controls the default QoS class (the QoS class for frames not classified in any other way). There is a one to one mapping between QoS class, queue and priority. A QoS class of 0 (zero) has the lowest priority. tnQosExtL2CosIfClassifDefaultClass is a number in the range (0..(dot1dPortNumTrafficClasses-1))

What is tnQosExtL2CosIfClassifDefaultClass?

Sets the default QoS class (queue and priority) assigned to frames on this interface that aren't classified any other way; class 0 is the lowest priority, and each class maps one-to-one to a queue.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.868.2.5.9.1.2.1.1.1
snmpwalk -v2c -c public <target> TN-QOS-EXT-MIB::tnQosExtL2CosIfClassifDefaultClass

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.868.2.5.9.1.2.1.1.1.1
snmpget -v2c -c public <target> TN-QOS-EXT-MIB::tnQosExtL2CosIfClassifDefaultClass.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.868.2.5.9.1.2.1.1.1.1 i <value>
