What Is CT-DAWANCONN-MIB?

CT-DAWANCONN-MIB is a Cabletron/Enterasys vendor MIB for monitoring direct-attached WAN (DAWAN) connections, covering call-level connection state, statistics, and link quality for WAN interfaces directly attached to Cabletron networking equipment. It exposes data about individual WAN connections/calls, including their establishment state and accumulated statistics that describe link performance over the life of the connection. Its monitoring emphasis is on WAN link and connection-fault status: detecting when a WAN call fails to establish, drops unexpectedly, or exhibits degraded link quality, which are the primary hardware/circuit-level faults operators care about on WAN-attached routing equipment. It is a companion to CT-DAWANDEVCONN-MIB, which covers device-level connection parameters, so the two are typically read together for full circuit visibility. It is deployed on legacy Cabletron/Enterasys routers or WAN concentrators providing direct WAN circuit attachment. Network engineers evaluating or troubleshooting this functionality can download the CT-DAWANCONN-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CT-DAWANCONN-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 monitor per-connection call state objects to catch a WAN call that failed to establish or dropped mid-session, and review accumulated link-quality statistics to detect a circuit with rising error rates before it fails outright. Since no sample objects were provided for this MIB, exact object names cannot be cited; this reflects the general call-state/link-quality monitoring pattern typical of Cabletron DAWAN connection MIBs.

What Can Be Monitored

WAN call/connection state
connection establishment failures
link quality statistics
connection uptime

OIDs

OID symbolic	OID numeric	Type	Access	Description
ctSSA	1.3.6.1.4.1.52.4497
daWanConnection	1.3.6.1.4.1.52.4497.17
INT daWanNumConnections	1.3.6.1.4.1.52.4497.17.1	INTEGER	read-only	This is the total number of connection objects currently in the system.
daWanConnectionTable	1.3.6.1.4.1.52.4497.17.2		not-accessible	A list of Demand Access remote WAN connections
daWanConnectionEntry	1.3.6.1.4.1.52.4497.17.2.1		not-accessible	An entry containing wan connection information and statistics.
INT daWanConnectionIndex	1.3.6.1.4.1.52.4497.17.2.1.1	INTEGER	read-only	This is the index into this table. This index uniquely identifies the Connection.
INT daWanConnectionIfIndex	1.3.6.1.4.1.52.4497.17.2.1.2	INTEGER	read-only	This is the ifIndex value of the wan connection group. If the ifIndex value is unknown, the value of this object will be zero.
INT daWanConnectionState	1.3.6.1.4.1.52.4497.17.2.1.3	INTEGER	read-only	This is the state of the Connection.
INT daWanConnectionConnectControl	1.3.6.1.4.1.52.4497.17.2.1.4	INTEGER	read-write	This object controls the desired state of the wan Connection. Setting this object to connect(1) will initiate the set of actions to bring the wan Connection to the active state. Only set the object to connect(1) when the current value of daWanConnectionState is inactive. Setting this object to disconnect(2) will initiate the set of actions to bring the wan Connection to the inactive state. Only set this object to disconnect(2) when the daWanConnectionState is active. After setting the Connection to connect(1) or disconnect(2), refer to daWanConnectionState to determine the state of the wan Connection. Queries to daWanConnectionConnectControl return unknown results.
INT daWanConnectionConnectType	1.3.6.1.4.1.52.4497.17.2.1.5	INTEGER	read-only	This specifies the type of the wan connection.
INT daWanConnectionDeviceIndex	1.3.6.1.4.1.52.4497.17.2.1.6	INTEGER	read-only	This is the index of the device that is associated with this connection. This value will be zero if there is no device associated with this device.
GAU daWanConnectionConnectSpeed	1.3.6.1.4.1.52.4497.17.2.1.7	Gauge	read-only	The information transfer speed in bits/second when calling this peer. The detailed media specific information, e.g. information type and information transfer rate for ISDN circuits, has to be extracted from this object. If the transfer speed to be used is unknown the value of this object may be zero.
STR daWanConnectionLocalAddress	1.3.6.1.4.1.52.4497.17.2.1.8	DisplayString	read-only	Call Address at which the connection will originate from. Think of this as the set of characters following 'ATDT ' or the 'phone number' included in a D channel call request. The structure of this information will be switch type specific. If there is no address information required for reaching the peer, i.e., for leased lines, this object will be a zero length string.
STR daWanConnectionPeerAddress	1.3.6.1.4.1.52.4497.17.2.1.9	DisplayString	read-only	Calling Party Number information element, as for example passed in an ISDN SETUP message by a PBX or switch, for incoming calls. This address can be used to identify the peer. If this address is either unknown or identical to daWanConnectionLocalAddress, this object will be a zero length string.
STR daWanConnectionSubAddress	1.3.6.1.4.1.52.4497.17.2.1.10	DisplayString	read-only	Subaddress at which the connection will originate from. If the subaddress is undefined for the given media or unused, then the value is zero.
INT daWanConnectionInfoType	1.3.6.1.4.1.52.4497.17.2.1.11	INTEGER	read-only	The Information Transfer Capability to be used for this connection. speech(2) refers to a non-data connection, whereas audio31(6) and audio7(7) refer to data mode connections.
INT daWanConnectionChargedUnits	1.3.6.1.4.1.52.4497.17.2.1.12	INTEGER	read-only	The number of charged units for this connection. For incoming calls or if charging information is not supplied by the switch, the value of this object will be zero.
TIM daWanConnectionConnectTime	1.3.6.1.4.1.52.4497.17.2.1.13	TimeStamp	read-only	The value of sysUpTime when this connection was completed. This object will be updated whenever a call is completed.
INT daWanConnectionConnectDirection	1.3.6.1.4.1.52.4497.17.2.1.14	INTEGER	read-only	The direction from which this connect occurred.
TIM daWanConnectionDisconnectTime	1.3.6.1.4.1.52.4497.17.2.1.15	TimeStamp	read-only	The value of sysUpTime when this call was disconnected. This object will be updated whenever a call is disconnected.
INT daWanConnectionDisconnectDirection	1.3.6.1.4.1.52.4497.17.2.1.16	INTEGER	read-only	The direction from which this disconnect occurred.
INT daWanConnectionDisconnectCause	1.3.6.1.4.1.52.4497.17.2.1.17	INTEGER	read-only	The encoded network cause value associated with this call. This object will be updated whenever a call is started or cleared. The value of this object will depend on the interface type as well as on the protocol and protocol version being used on this interface.
STR daWanConnectionDisconnectText	1.3.6.1.4.1.52.4497.17.2.1.18	DisplayString	read-only	ASCII text describing the reason for this call termination. This object exists because it would be impossible for a management station to store all possible cause values for all types of interfaces. It should be used only if a management station is unable to decode the value of daWanConnectionDisconnectCause. This object will be updated whenever a call is started or cleared.
