pwMplsExpBits

Module: PW-MPLS-STD-MIB

OID (symbolic): PW-MPLS-STD-MIB::pwMplsExpBits

OID (numeric): 1.3.6.1.2.1.181.1.1.1.3

Node type: OBJECT-TYPE

Type: Unsigned32

Access: read-write

Description: This object is set by the operator if pwMplsExpBitsMode is set to specifiedValue(2) to indicate the MPLS EXP bits to be used on the PW shim label. Otherwise, it SHOULD be set to zero.

What is pwMplsExpBits?

This value, from 0 to 7, is the MPLS EXP bits value to use on the pseudowire shim label, applicable when pwMplsExpBitsMode is set to specifiedValue; it should otherwise be left at its default of zero. Admins set it to control the QoS class-of-service marking carried directly on the exposed PW label. Setting pwMplsExpBits to 5 marks that pseudowire's traffic with a higher-priority EXP value for QoS handling along the path.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.181.1.1.1.3
snmpwalk -v2c -c public <target> PW-MPLS-STD-MIB::pwMplsExpBits

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.181.1.1.1.3.1
snmpget -v2c -c public <target> PW-MPLS-STD-MIB::pwMplsExpBits.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.2.1.181.1.1.1.3.1 i <value>
