Features
MCG-101 v2 SNMP Functionality
Simple Network Management Protocol SNMP is a widely used protocol for monitoring the health and welfare of network equipment. The MCG-101 provides some limited information over SNMP to query various values. SNMPD is the master daemon/agent for SNMP, from the net-snmp project. For more information on SNMP, see resources below.
SNMP Functionality
SNMPD can be configured to either run over UDP or TCP. The protocol and port can be set in the SNMPD configuration User Interface. SNMPD listens to a variety of GPS and Iridium broadcast messages, and some events that require polling. The behavior, source, and possible delay of each is noted below:
| NMP Service | Object Identifier (OID) | Format | Source | Instantaneous /Delayed | Instantaneous /Delayed |
|---|---|---|---|---|---|
| Real Time Clock | 1.3.6.1.4.1.3804 0.11.6.0 | string | GPS | Instantaneous | Report time acquired from GPS chipset after GPS signal has been acquired. Does require a GPS antenna to be connected NMEA date and time as YY:MM:DD:HH:MM:SS. If no fix, then the string 00:00:00:00:00:00 |
| Link Quality | 1.3.6.1.4.1.3804 0.11.15.0 | integer | Iridium DPL Port | Instantaneous | Report last known signal level broadcasted from the Iridium DPL port. Does not force a query, but instead reports the signal level based on what would be displayed on an Iridium handset. Values are 0-5 |
| Lock/Unlock Status | 1.3.6.1.4.1.3804 0.11.13.0 | integer | Iridium Data Port | Delayed, must query Iridium Data port | Query the CULK status using an AT command that shares the single port between dial up data, SMS, and SBD. The Iridium Data port is first come first serve and this command can be denied if already busy. Values are 0 - not locked (can do SBD), 1 - locked (cannot do SBD), 2 - permanently locked |
| Error Status | 1.3.6.1.4.1.3804 0.11.16.0 | integer | Iridium Data Port | Delayed, must query Iridium Data port | Query the CMEE status using an AT command that shares the single port between dial up data, SMS, and SBD. The Iridium Data port is first come first serve and this command can be denied if already busy Values: 0 - disabled, 1 - numeric error reporting enabled, 2 verbose error reporting enabled |
