dot3ExtPkgOptIfSignalDetect

Module: DOT3-EPON-MIB

OID (symbolic): DOT3-EPON-MIB::dot3ExtPkgOptIfSignalDetect

OID (numeric): 1.3.6.1.2.1.155.1.4.1.5.1.12

Node type: OBJECT-TYPE

Type: TruthValue

Access: read-only

Description: When getting true(1), there is a valid optical signal at the receive that is above the optical power level for signal detection. When getting false(2) the optical signal at the receive is below the optical power level

for signal detection. This object is applicable for an OLT and an ONU. At the OLT, it has a distinct value for each virtual interface.

What is dot3ExtPkgOptIfSignalDetect?

This reports whether a valid optical receive signal above the detection threshold is currently present (true) or not (false) on this interface. It's the fastest way for an admin to check for a hard optical loss-of-signal condition, distinct from a signal merely below quality thresholds.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.155.1.4.1.5.1.12
snmpwalk -v2c -c public <target> DOT3-EPON-MIB::dot3ExtPkgOptIfSignalDetect

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.155.1.4.1.5.1.12.1
snmpget -v2c -c public <target> DOT3-EPON-MIB::dot3ExtPkgOptIfSignalDetect.1
