gpsFaultStatus

Module: MERIDIAN2-MIB

OID (symbolic): MERIDIAN2-MIB::gpsFaultStatus

OID (numeric): 1.3.6.1.4.1.13827.14.2.1

Node type: OBJECT-TYPE

Type: Bits

Access: read-only

Description: This is a bit string contained in one character representing the least significant two nibbles of the GPS fault status word. Unfortunately, SNMP numbers the bits in the reverse order, so that the enumerated values are backwards from the description contained in the User's Manual for the fault status field returned by the gpsstat command. Each bit indicates a fault when set. Currently defined fault states encoded in this value:

Bit 7: DAC controlling the TCXO is near the high or low limit. Bit 6: Time Figure of Merit has been >= TFOM Fault Level for 1 hour. Bit 5: Field Programmable Gate Array (FPGA) did not configure properly. Bit 4: FLASH memory had a write fault. Bit 3: GPS receiver communication fault. Bit 2: GPS reference time fault (fails sanity checks). Bit 1: NTP daemon is not polling the GPS reference clock. Bit 0: GPS receiver fault.

ATTENTION: This object is deprecated for use in snmpget queries due to a defect in reporting for one specific combination of bits. It remains in this MIB for use with the gpsTrapFaultStatusChange object, where it reports accurately.

Use the new gpsFaultNibble0Status and gpsFaultNibble1Status objects for querying via snmpget.

What is gpsFaultStatus?

A BITS value packing the low two nibbles of the legacy GPS fault status word (receiver fault, NTP not polling GPS, reference-time sanity-check fault, receiver comm fault, flash write fault, FPGA config fault, no-signal timeout, and DAC near limit); each bit is set when that fault is active. The DESCRIPTION flags this object as deprecated for snmpget due to a reporting defect on one bit combination -- it's kept only for the gpsTrapFaultStatusChange trap, and gpsFaultNibble0Status/gpsFaultNibble1Status should be polled instead.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.13827.14.2.1
snmpwalk -v2c -c public <target> MERIDIAN2-MIB::gpsFaultStatus

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.13827.14.2.1.1
snmpget -v2c -c public <target> MERIDIAN2-MIB::gpsFaultStatus.1
