Description: MIB for on-demand port loopback tests and diagnostics on Smartoptics SiteLight optical networking equipment

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is SL-TESTS-MIB?

SL-TESTS-MIB is a vendor MIB from Smartoptics providing on-demand diagnostic loopback testing for interfaces on its SiteLight optical transport platform, letting operators trigger and read back the results of test loopbacks without needing separate test equipment. It defines a table of loopback test instances per interface, covering test type, mode, duration, and outcome. Its monitoring role is diagnostic rather than continuous telemetry: slTestsIfLoopStatus and slTestsIfLoopResult report whether a triggered loopback test is running or complete and whether it passed or failed, slTestsIfLoopErrors counts errors detected during the test, and slTestsIfLoopPassedSeconds shows how much of the test duration completed cleanly — useful for isolating a faulty span of fiber or a suspect line card. A trap (slTestsTrapsLoopbackActive) notifies when a loopback is active, which is important operationally since a loopback interrupts normal traffic. It is part of the SiteLight family and is used during commissioning or fault isolation on SiteLight optical transport links. Engineers can download the SL-TESTS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in SL-TESTS-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Monitoring Examples

A technician sets slTestsIfLoopType and slTestsIfLoopMode on slTestsIfLoopTable/slTestsIfLoopEntry indexed by slTestsIfLoopIfIndex, sets slTestsIfLoopDuration, and then polls slTestsIfLoopStatus to watch the test progress and slTestsIfLoopResult once it completes. A nonzero slTestsIfLoopErrors count together with a low slTestsIfLoopPassedSeconds relative to the configured duration would indicate the interface or its fiber path is faulty, while the slTestsTrapsLoopbackActive trap reminds other operators that the port is currently in loopback and not passing live traffic.

What Can Be Monitored

loopback test result (pass/fail)
error count during test
test duration and passed seconds

OIDs

OID symbolic	OID numeric	Type	Access	Description
slTests	1.3.6.1.4.1.4515.1.3.13			This MIB module describes the available on-demand tests.
slTestsIfLoop	1.3.6.1.4.1.4515.1.3.13.1
slTestsIfLoopTable	1.3.6.1.4.1.4515.1.3.13.1.1		not-accessible	The port loopback test table. This table controls the port loopback tests.
slTestsIfLoopEntry	1.3.6.1.4.1.4515.1.3.13.1.1.1		not-accessible	This entry is used to operate an port loopback test.
NUM slTestsIfLoopIfIndex	1.3.6.1.4.1.4515.1.3.13.1.1.1.1	InterfaceIndex	read-only	The Interface Index of the port that should be loopped back.
INT slTestsIfLoopDuration	1.3.6.1.4.1.4515.1.3.13.1.1.1.2	INTEGER	read-write	The test duration in 1/10 Sec. The maximum allowed duration is 1 hour. After this time the port configuration returns to its original setting and the Agent automatically deletes the entry from the table.
INT slTestsIfLoopStatus	1.3.6.1.4.1.4515.1.3.13.1.1.1.3	INTEGER	read-write	This variable is used to start or stop a loopback test. In order to start a test the NMS should set the value to start(1). If the test mode is toggle, the NMS should stop the test by setting the value to stop(2). In the case of prbs test, after the test has stopped, if the test fails the value of the status shall be fail(3).
INT slTestsIfLoopType	1.3.6.1.4.1.4515.1.3.13.1.1.1.5	INTEGER	read-write	The loopback type: facility The received signal at this interface is looped back out through the corresponding transmitter in the return direction. terminal The signal that is about to be transmitted is connected to the associated incoming receiver. prbs send and recieve prbs pattern. otnPrbs send and receive OTN prbs
INT slTestsIfLoopMode	1.3.6.1.4.1.4515.1.3.13.1.1.1.6	INTEGER	read-write	The loopback mode: timeout In this mode the duration of the loopback is determined by the slTestsIfLoopDuration object. toggle In this mode the loopback should be toggled explicitly by the user.
C32 slTestsIfLoopErrors	1.3.6.1.4.1.4515.1.3.13.1.1.1.7	Counter32	read-only	The prbs errors are counted only of the test succeeded.
INT slTestsIfLoopResult	1.3.6.1.4.1.4515.1.3.13.1.1.1.8	INTEGER	read-only	This variable is used for prbs test result indication.
INT slTestsIfLoopPassedSeconds	1.3.6.1.4.1.4515.1.3.13.1.1.1.9	INTEGER	read-only	Number of seconds passed since the test started.
slTestsTraps	1.3.6.1.4.1.4515.1.3.13.2
slTestsTraps0	1.3.6.1.4.1.4515.1.3.13.2.0
NTF slTestsTrapsLoopbackTableChanged0	1.3.6.1.4.1.4515.1.3.13.2.0.2			A slTestsTrapsLoopbackTableChanged trap is sent when the content of slTestsIfLoopTable changes. When the loop back is deleted the returned value of slTestsIfLoopActivity should be false.
T/F slTestsTrapsLoopbackActive	1.3.6.1.4.1.4515.1.3.13.2.1	TruthValue	read-only	The Loopback is active Yes/No.
NTF slTestsTrapsLoopbackTableChanged	1.3.6.1.4.1.4515.1.3.13.2.2			A slTestsTrapsLoopbackTableChanged trap is sent when the content of slTestsIfLoopTable changes. When the loop back is deleted the returned value of slTestsIfLoopActivity should be false.
