What is hdlcLoopbackState?

Puts the HDLC port into a diagnostic loopback: internal loops all data coming from the network port back on itself, external loops data coming in from the line back out, and disable turns loopback off; an admin uses this to isolate whether a link problem is on the local equipment or further out on the circuit.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.164.3.1.6.5.1.1.5
snmpwalk -v2c -c public <target> RAD-HDLC-MIB::hdlcLoopbackState

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.164.3.1.6.5.1.1.5.1
snmpget -v2c -c public <target> RAD-HDLC-MIB::hdlcLoopbackState.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.164.3.1.6.5.1.1.5.1 i <value>
