What Is DIGI-MOBILE-INFORMATION-MIB?

This is a Digi International vendor MIB providing status information for the cellular mobile interface(s) on Digi's cellular-equipped routers and gateways. It exposes a generic name/value information structure that enumerates mobile interfaces and reports per-interface fields such as carrier, signal quality, and connection state under a flexible info table rather than fixed dedicated objects. As a monitoring module it is directly useful for confirming the software/hardware status of the device's cellular WAN connection -- whether the modem currently has signal and is attached to a carrier network -- which is critical for devices relying on cellular as a primary or backup WAN link. It layers on top of the standard interfaces model (paralleling ifIndex-style interface identification) to associate mobile info with a specific network interface. It is deployed on Digi cellular routers/gateways used for remote sites, kiosks, or IoT/M2M deployments where a cellular modem provides WAN connectivity, monitored via SNMP. Engineers can download the DIGI-MOBILE-INFORMATION-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in DIGI-MOBILE-INFORMATION-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

Digi cellular router/gateway (e.g. Digi TransPort or IX-series with embedded cellular modem)

Monitoring Examples

Polling miTable (miNumber, miIndex) enumerates the mobile interfaces present on the device, and for each one, miInfoTable rows keyed by miInfoInterface and miInfoIndex expose miInfoName/miInfoValue pairs such as signal strength or carrier name; a miInfoValue showing very low signal or a 'no service' condition would explain a cellular backhaul link that has become unreliable or dropped. miNumFields indicates how many such info fields are available per interface, letting a management script know how much data to expect.

What Can Be Monitored

mobile interface count/enumeration
carrier/signal strength info
cellular connection state
per-interface info field values

OBJECT-TYPE

OIDs

OID symbolic	OID numeric	Type	Access	Description
INT miNumber	1.3.6.1.4.1.332.11.6.3.1	INTEGER	read-only	The number of network interfaces (regardless of their current state) present on this system. The interface identifiedby a particular value of this index is the sameinterface as identified by the same value of ifIndex.
miTable	1.3.6.1.4.1.332.11.6.3.2		not-accessible	A list of mobile interface information entries. The number of possible entries is given by the value of miNumber.
miEntry	1.3.6.1.4.1.332.11.6.3.2.1		not-accessible	A mobile interface information entry containing the number of information name/value pairs available for read
INT miIndex	1.3.6.1.4.1.332.11.6.3.2.1.1	INTEGER	read-only	A unique value for each interface. Its value ranges between 1 and the value of miNumber. The value for each interface must remain constant at least from one re-initialization of the entity's network management system to the next re- initialization. The interface identified by a particular value of this index is the same interface as identified by the same value of ifIndex.
INT miNumFields	1.3.6.1.4.1.332.11.6.3.2.1.2	INTEGER	read-only	The number of information fields associated with this interface.
miInfoTable	1.3.6.1.4.1.332.11.6.3.3		not-accessible	A table of information name/value pairs
miInfoEntry	1.3.6.1.4.1.332.11.6.3.3.1		not-accessible	An information name/value pair entry
INT miInfoInterface	1.3.6.1.4.1.332.11.6.3.3.1.1	INTEGER	read-only	A unique value for each interface. Its value ranges between 1 and the value of miNumber. The value for each interface must remain constant at least from one re-initialization of the entity's network management system to the next re- initialization. The interface identified by a particular value of this index is the same interface as identified by the same value of ifIndex.
INT miInfoIndex	1.3.6.1.4.1.332.11.6.3.3.1.2	INTEGER	read-only	A unique value for each information Name/Value pair ranges between 1 and the value of miNumFields. The value for each interface must remain constant at least from one re-initialization of the entity's network management system to the next re- initialization.
OCT miInfoName	1.3.6.1.4.1.332.11.6.3.3.1.3	OCTET STRING	read-only	The name portion of this information name/value pair
OCT miInfoValue	1.3.6.1.4.1.332.11.6.3.3.1.4	OCTET STRING	read-only	The value portion of this information name/value pair
