Description: Provides physical layer (PHY) diagnostics and configuration objects for Dell switch ports.

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 Dell-PHY-MIB?

This Dell private MIB provides Layer 1 physical-layer diagnostic testing for switch ports, such as cable diagnostics used to detect wiring faults. It exposes a test-set table for initiating a diagnostic test and a corresponding test-get table for retrieving the test's status, result, units, and any alarm condition. It is squarely a hardware-health monitoring tool: the test result, alarm flag, and timestamp reveal cable faults such as opens, shorts, or impedance mismatches on a specific port, which is directly useful for troubleshooting suspected physical-link problems. It complements the standard IF-MIB physical interface objects for the same ports. It is typically deployed on Dell switches where technicians run on-demand cable diagnostics to isolate physical-layer link issues. Engineers can download the Dell-PHY-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Dell-PHY-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.

Supported Devices

Dell network switch (PowerConnect/N-Series family)

Monitoring Examples

A technician initiates a cable test by writing to rlPhyTestSetTable/rlPhyTestSetEntry with a chosen rlPhyTestSetType, then polls rlPhyTestGetTable/rlPhyTestGetEntry for rlPhyTestGetStatus to see when the test completes. The rlPhyTestGetResult and rlPhyTestGetUnits objects report the measured value (such as estimated cable length to a fault), while rlPhyTestGetAlarm flags whether an abnormal condition like an open or short was detected. rlPhyTestGetTimeStamp records when the test ran, letting the technician correlate results with a specific troubleshooting session.

What Can Be Monitored

physical layer test status
test result value and units
test alarm flag
test execution timestamp

OIDs

OID symbolic	OID numeric	Type	Access	Description
rlPhy	1.3.6.1.4.1.89.90			The MIB module describes the private MIB for testing Layer1 interfaces supported by Dell's software and products.
rlPhyTest	1.3.6.1.4.1.89.90.1
rlPhyTestSetTable	1.3.6.1.4.1.89.90.1.1		not-accessible
rlPhyTestSetEntry	1.3.6.1.4.1.89.90.1.1.1		not-accessible	An entry containing objects for invoking tests on an interface.
RLP rlPhyTestSetType	1.3.6.1.4.1.89.90.1.1.1.1	RlPhyTestType	read-write	A control variable used to start operator initiated interface tests.1 indicates that no test has been initiated. Only operator initiated interface tests can be set to this variable.
rlPhyTestGetTable	1.3.6.1.4.1.89.90.1.2		not-accessible
rlPhyTestGetEntry	1.3.6.1.4.1.89.90.1.2.1		not-accessible	An entry containing results of tests on an interface.
RLP rlPhyTestGetType	1.3.6.1.4.1.89.90.1.2.1.1	RlPhyTestType	read-only	A control variable used to, 1 to indicate that this test can be done on the specified port, 2 to initiate the test whenever the user wishes
INT rlPhyTestGetStatus	1.3.6.1.4.1.89.90.1.2.1.2	INTEGER	read-only	This object contains the status of the most recently requested test for operator initiated tests or the value none(1) if no tests have been requested since the last reset. For non operator initiated tests the value is always none(1). Note that this facility provides no provision for saving the results of one test when starting another, as could be required if used by multiple managers concurrently.
INT rlPhyTestGetResult	1.3.6.1.4.1.89.90.1.2.1.3	INTEGER	read-only	This object holds the test result
INT rlPhyTestGetUnits	1.3.6.1.4.1.89.90.1.2.1.4	INTEGER	read-only	The test result unit of measure. The units can be standard unit or special units that are designed for special test. The alaskaPhyLength unit is design for the VCT diagnostic and its values are: less_than_50M(1), 50-80M(2), 80-110M(3), 110-140M(4), more_than_140M(5). The alaskaPhyStatus unit is design for the VCT diagnostic and its values are: 4_pair_cable(1), 2_pair_cable(2), no_cable(3), open_cable(4), short_cable(5), bad_cable(6), impedance_mismatch(7).
INT rlPhyTestGetAlarm	1.3.6.1.4.1.89.90.1.2.1.5	INTEGER	read-only	This object hold the Alarm for this Entry. only Test that have can have alarms use this field, other holds the Value notRelevant(1)
STR rlPhyTestGetTimeStamp	1.3.6.1.4.1.89.90.1.2.1.6	DisplayString	read-only	The time in string (formated DD-MMM-YYYY HH:MM:SS e.g 14-Apr-2002 10:33:31)
