oc3LoopbackConfig

Module: ACMIB

OID (symbolic): ACMIB::oc3LoopbackConfig

OID (numeric): 1.3.6.1.4.1.1751.2.18.2.6.1.2

Description: This variable represents the loopback configuration of the OC3 interface

See above diagrams for explanations of loops.

What is oc3LoopbackConfig?

This OID controls the internal loopback configuration of an OC3 port, allowing it to loop traffic back to itself for testing. Network engineers enable loopback during maintenance or troubleshooting to verify the port's transmit and receive circuitry without affecting live traffic. Setting this to 'internalLoop' causes the port to forward its own transmitted data back to its receiver, enabling self-test diagnostics.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.2.6.1.2
snmpwalk -v2c -c public <target> ACMIB::oc3LoopbackConfig

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.2.6.1.2.1
snmpget -v2c -c public <target> ACMIB::oc3LoopbackConfig.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.1751.2.18.2.6.1.2.1 i <value>
