Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is USR-DIALOUT-MIB?

This MIB, from the commWorks (U.S. Robotics/3Com) enterprise, manages dial-out connection profiles, security settings, and per-port call statistics on CommWorks/3Com dial access equipment. It exposes global dial-out configuration (config file name, security mode, timeouts) alongside a per-port table tracking each port's identity, naming, and current call/client state. For monitoring, the per-port state object reveals the live operational status of each dial-out port (e.g., idle, dialing, connected), letting an operator track active outbound calls and detect ports stuck in a failed or hung state, while the workstation/user timeout settings govern session-level fault recovery. It is a vendor-proprietary MIB specific to the commWorks enterprise, with no strong indicated dependency on external standard MIBs beyond general SNMPv2 conventions. Typically deployed on USR/CommWorks/3Com dial access servers providing remote access or dial-out connectivity in enterprise/carrier access networks, where USR-DIALOUT-MIB SNMP monitoring tracks per-port call state and session health.

IPNetwork Monitor allows you to monitor SNMP objects defined in USR-DIALOUT-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 administrator would poll usrDialoutPortTable/usrDialoutPortEntry keyed by usrDialoutPortNumber to see each port's usrDialoutPortState, identifying which ports currently have an active outbound call versus which are idle or stuck. Checking usrDialoutPortClientType alongside usrDialoutPortGeneralName/usrDialoutPortSpecificName helps identify which client or profile initiated a given call, while usrDialoutCFMStatusFlag and usrDialoutSecurity reveal whether call management/security features are enabled, useful when diagnosing why dial-out attempts are being rejected.

What Can Be Monitored

per-port dial-out call state
active outbound call tracking
dial-out security/authentication mode
session timeout configuration
client/profile identification per call

OIDs

OID symbolic	OID numeric	Type	Access	Description
usrDialout	1.3.6.1.4.1.429.4.25			The commWorks enterprise defined MIB objects for Dialout.
STR usrDialoutConfigFileName	1.3.6.1.4.1.429.4.25.1	DisplayString	read-only	The name of a ConfigFile to read/write permanent database records. If the value of this object is an empty string, then the Dial-out process uses the default name `@file://DialOutProcess.cfg'.
USR usrDialoutCFMStatusFlag	1.3.6.1.4.1.429.4.25.2	UsrConfigStatus	read-write	Setting the value of this object to `save' causes the values of the Dial-out Group to be written out to the current config file, which is stored in the usrDialoutConfigFileName object. While the new ConfigFile is being written, the Dial-out process will set the value of this flag to `saving''. Any attempts to set the value while it is not `normal' (i.e. the file is currently being written to the ConfigFile) while result in a badValue error being returned. Setting the value to `normal' will result in no action.
INT usrDialoutSecurity	1.3.6.1.4.1.429.4.25.3	INTEGER	read-write	Setting the value of this object to yes(2) will instruct the Dial-out process to authenticate all network users who attempt to connect to a virtual port. Setting the value of this object to no(1) will instruct the Dial-out process to bypass the user authentication process.
I32 usrDialoutWorkstationTimeout	1.3.6.1.4.1.429.4.25.4	Integer32	read-write	Even when it appears there is no activity on a connected virtual port, the client and server are still actively sending and receiving messages. If the client is re-booted, or if the client experiences a system error that interrupts this activity, the server will wait a certain amount of time before terminating the connection. Depending on what caused the interruption, this period of time may allow the client to restore the connection. This time-out value is specified in minutes. The default is 5 minutes. To disable workstation time-out, set this object to 0.
I32 usrDialoutUserTimeout	1.3.6.1.4.1.429.4.25.5	Integer32	read-write	The User time-out is provided so that a virtual port will be freed for use by others when the current user is not actively using the virtual port. If the server does not receive any transmit data requests from the client for the period of the time-out, the session is disconnected. The time-out value is specified in minutes. The default is 5 minutes. To disable user time-out, set this object to 0.
usrDialoutPortTable	1.3.6.1.4.1.429.4.25.6		not-accessible	A list of virtual ports available for dial-out.
usrDialoutPortEntry	1.3.6.1.4.1.429.4.25.6.1		not-accessible	An entry containing management information applicable to a particular virtual port.
I32 usrDialoutPortNumber	1.3.6.1.4.1.429.4.25.6.1.1	Integer32	not-accessible	The virtual port number of the dial-out port.
STR usrDialoutPortGeneralName	1.3.6.1.4.1.429.4.25.6.1.2	DisplayString	read-only	The general service name associated with a virtual port. When a network user requires access to a type of service, rather than a specific port, the user is able to request a service by its general name. This provides network users access to the communication server ports without requiring the user to know the specific name or location of a port.
STR usrDialoutPortSpecificName	1.3.6.1.4.1.429.4.25.6.1.3	DisplayString	read-only	The specific name associated with a virtual port. This allows a network user to locate a particular port for access to a specific service associated with that port.
INT usrDialoutPortState	1.3.6.1.4.1.429.4.25.6.1.4	INTEGER	read-write	The state of the virtual port. When a port is in the available(1) state, it is available to a network user. When a port is in the unavailable(2) state, it is not available to a network user. When a port is in the in-use(3) state, it is currently in use by a network user. Setting this object to disconnect(4) will cause a supervisory disconnect of the current user. Setting this object to any other value will have no effect.
INT usrDialoutPortClientType	1.3.6.1.4.1.429.4.25.6.1.5	INTEGER	read-only	The type of client that is attached to this port. This object is set to none(0) if no client is attached to the port.
OCT usrDialoutPortIpxClientAddress	1.3.6.1.4.1.429.4.25.6.1.6	OCTET STRING	read-only	The Ethernet address of the IPX client workstation attached to the port. If no client is attached to the port or an IP client is attached to the port, this object is set to all zeros.
IP usrDialoutPortIpClientAddress	1.3.6.1.4.1.429.4.25.6.1.7	IpAddress	read-only	The IP address of the IP client workstation attached to the port. If no client is attached to the port or an IPX client is attached to the port, this object is set to all zeros.
