What Is Wellfleet-Modem-MIB?

Wellfleet-Modem-MIB is a vendor-specific MIB from Wellfleet Communications (later Bay Networks/Nortel) written to manage the internal V.34 modem daughter card used on the NEPTUNE platform. Its single wfModemTable, indexed by wfModemSlot and wfModemConnector, models per-line modem state through objects like wfModemLineState, wfModemConnectionFailReason, wfModemCfgState, and wfModemInitState, alongside configuration objects such as wfModemCfgInitString, wfModemPhoneNumber, and wfModemType that let Site Manager push AT command strings to the modem. It also exposes V.54 loopback test controls (wfModemV54Lpbk, wfModemV54Timer, wfModemV54Errors) for diagnosing line quality and remote loopback behavior. The MIB imports Counter from RFC1155-SMI, OBJECT-TYPE from RFC-1212, DisplayString from RFC1213-MIB, and wfModemGroup from Wellfleet-COMMON-MIB, tying it into Wellfleet's broader router MIB tree. Administrators managing legacy Wellfleet/Bay Networks routers with dial-backup modem cards can download the Wellfleet-Modem-MIB download file to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Wellfleet-Modem-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.

Monitoring Examples

An operator polls wfModemLineState and wfModemConnectionFailReason on a given wfModemSlot/wfModemConnector pair to check whether a dial-backup modem is connected, and a line stuck in busiedOut or repeatedly reporting lossOfCarrier or noResponseFromRemote in wfModemConnectionFailReason would indicate a failing modem or bad phone line.

What Can Be Monitored

Modem line state per slot/connector
Connection failure reason codes
V.54 loopback test results and error counts
Modem initialization/configuration state
Firmware and hardware revision strings

OIDs

OID symbolic	OID numeric	Type	Access	Description
INT wfModemCfgCountry	1.3.6.1.4.1.18.3.4.29.1.1.13	INTEGER	read-write	Identifies the country the modem is designed to operate in. This object is not read from the modem directly. It must be entered manually when configuring the modem.
STR wfModemCfgDefaultString	1.3.6.1.4.1.18.3.4.29.1.1.10	DisplayString	read-only	The string contains AT comands for initializing the modem every time the modem comes up, regardless of configuration.
INT wfModemCfgFactoryDefaults	1.3.6.1.4.1.18.3.4.29.1.1.8	INTEGER	read-write	This object indicates if factory defaults are to be loaded. If set to enabled(1), factory defaults are loaded. If set to disabled(2), the initialization string in wfModemCfgInitString is sent to the modem.
STR wfModemCfgInitString	1.3.6.1.4.1.18.3.4.29.1.1.9	DisplayString	read-write	An initialization string that will be sent to the modem each time the modem is rebooted.
STR wfModemCfgResultCodeString	1.3.6.1.4.1.18.3.4.29.1.1.11	DisplayString	read-only	The ASCII response string returned by the modem. Response strings will be returned in response to last command to the modem and in response to activity on the line.
INT wfModemCfgState	1.3.6.1.4.1.18.3.4.29.1.1.12	INTEGER	read-write	Indicates the state of AT command processing. When a new initialization string is to be sent to the modem, the sender sets the state to cfgInProgress(2). After the command has been sent to the modem, and a result code has been returned, the state is set to cfgResponseReturned(3). Once the sender has received the return code, the sender sets the state to cfgIdle(1).
INT wfModemConnectionFailReason	1.3.6.1.4.1.18.3.4.29.1.1.7	INTEGER	read-only	indicates the reason for the last failed connection
INT wfModemConnector	1.3.6.1.4.1.18.3.4.29.1.1.3	INTEGER	read-only	Instance ID Connector, filled in by the driver.
INT wfModemDelete	1.3.6.1.4.1.18.3.4.29.1.1.1	INTEGER	read-write	Create/Delete parameter
wfModemEntry	1.3.6.1.4.1.18.3.4.29.1.1		not-accessible	An entry in the MODEM table
STR wfModemIdHwRev	1.3.6.1.4.1.18.3.4.29.1.1.5	DisplayString	read-only	A textual description of the revision number of the modem daughter card.
STR wfModemIdSwRev	1.3.6.1.4.1.18.3.4.29.1.1.4	DisplayString	read-only	A textual description of the modem's firmware version number.
INT wfModemInitState	1.3.6.1.4.1.18.3.4.29.1.1.19	INTEGER	read-only	Indictes the state of the modem initialization sequence. The state will freeze in the state that fails when a failure is detected. Otherwise, the state will be set to initComplete when initialization completes successfully.
INT wfModemLineState	1.3.6.1.4.1.18.3.4.29.1.1.6	INTEGER	read-only	Indicates the state of the modem.
STR wfModemPhoneNumber	1.3.6.1.4.1.18.3.4.29.1.1.18	DisplayString	read-write	Contains the phone number for the modem to dial.
INT wfModemSlot	1.3.6.1.4.1.18.3.4.29.1.1.2	INTEGER	read-only	Instance ID Slot, filled in by driver
wfModemTable	1.3.6.1.4.1.18.3.4.29.1		not-accessible	Modem line record.
INT wfModemType	1.3.6.1.4.1.18.3.4.29.1.1.21	INTEGER	read-write	Enables a user to specify a modem type attached to the port thus enabling Site Manager to put a preconfigured modem init string in the wfModemInitString entry. The list of modems and init strings are stored in Site Manager for flexibility. This type can be set to Custom and a user defined string can be entered in wfModemInitString field.
INT wfModemUnitReset	1.3.6.1.4.1.18.3.4.29.1.1.20	INTEGER	read-write	Enables the operator to remotely reset the unit. Using this command will cause the unit to terminate all its connections and drop data.
CTR wfModemV54Errors	1.3.6.1.4.1.18.3.4.29.1.1.16	Counter	read-only	Indicates the number of errors reported during the last loopback test. This count will only be updated for loopbacks with test pattern.
INT wfModemV54Lpbk	1.3.6.1.4.1.18.3.4.29.1.1.14	INTEGER	read-write	Enables the operator to control, and examine the state of, V.54 loopbacks within the modem. This object equates to the AT&Tn command.
INT wfModemV54RemLpbkDetect	1.3.6.1.4.1.18.3.4.29.1.1.17	INTEGER	read-write	This object controls whether or not this modem will acknowledge V.54 Remote Loop 2 requests from a remote Site. When ENABLED, this modem can be put into a digital loopback from a remote site. When DISABLED, the modem will reject requests from the remote site.
INT wfModemV54Timer	1.3.6.1.4.1.18.3.4.29.1.1.15	INTEGER	read-write	Duration in seconds that a test specified in wfModemV.54Lpbk is to execute.
