msLOSDetection
Module: ACMIB
OID (symbolic): ACMIB::msLOSDetection
OID (numeric): 1.3.6.1.4.1.1751.2.18.2.4.1.23
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: State of detection of LOS by IO card. LOS detection is always enabled when msBitStuffing is enabled. When the interface is not circuit emulation, the IO card does not report any LOS.
What is msLOSDetection?
This OID enables or disables loss-of-signal detection on the multiserial port's input, allowing the IO card to recognize when the incoming signal disappears or degrades beyond usable thresholds. Network engineers enable this on circuit emulation links to trigger alarms when the physical layer fails. For instance, if you have a fiber optic connection and the cable is cut, enabling LOS detection will immediately alert you to the outage; however, if bit stuffing is enabled, the system forces LOS detection on automatically.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.2.4.1.23 snmpwalk -v2c -c public <target> ACMIB::msLOSDetection
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.2.4.1.23.1 snmpget -v2c -c public <target> ACMIB::msLOSDetection.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.1751.2.18.2.4.1.23.1 i <value>
