msLoopbackConfig

Module: ACMIB

OID (symbolic): ACMIB::msLoopbackConfig

OID (numeric): 1.3.6.1.4.1.1751.2.18.2.4.1.22

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: This variable represents the loopback configuration of the Serial port.

What is msLoopbackConfig?

This OID selects the loopback testing mode for the multiserial port, allowing local or remote loopback of transmitted data for diagnostic purposes. Network engineers use this to isolate whether a link problem is in the local equipment, the cable, or the remote end. For example, setting this to local loopback sends outgoing data directly back to the receiver; if you then see clean data echoed back, the port hardware is functional.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.2.4.1.22
snmpwalk -v2c -c public <target> ACMIB::msLoopbackConfig

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.2.4.1.22.1
snmpget -v2c -c public <target> ACMIB::msLoopbackConfig.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.1751.2.18.2.4.1.22.1 i <value>
