gpsFaultNibble0Status

Module: SONOMA-MIB

OID (symbolic): SONOMA-MIB::gpsFaultNibble0Status

OID (numeric): 1.3.6.1.4.1.13827.12.2.48

Node type: OBJECT-TYPE

Type: Bits

Access: read-only

Description: This is a bit string contained in one character representing the least significant nibble 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 3: DAC controlling the TCXO is near the high or low limit. Bit 2: Time Figure of Merit has been >= TFOM Fault Level for 1 hour. Bit 1: Field Programmable Gate Array (FPGA) did not configure properly. Bit 0: FLASH memory had a write fault.

What is gpsFaultNibble0Status?

Bit string giving the least-significant nibble of the GPS fault word (DAC near limit, TFOM at fault level, FPGA config fault, FLASH write fault), the reliable replacement for the deprecated gpsFaultStatus object when polling via snmpget.
