What Is CT-DAWAN-MIB?

CT-DAWAN-MIB is a Cabletron Systems (later Enterasys) proprietary MIB for managing Direct-Attached WAN (DAWAN) interface modules on Cabletron networking chassis. Although no sample objects were extracted for this module, its name and vendor lineage indicate it exposes WAN interface configuration and operational status, such as line type, framing, and link state for serial/WAN ports attached directly to the switch/router. As with other Cabletron hardware MIBs, it would be used to monitor the operational status of WAN interface hardware, including link up/down state and interface-level configuration, complementing standard interface counters. It likely depends on or extends the standard IF-MIB interface table (ifTable/ifEntry) for indexing, since Cabletron device MIBs commonly layer vendor extensions onto RFC 1213/IF-MIB conventions. It would have been deployed on legacy Cabletron/Enterasys routers and multiservice switches providing WAN connectivity in enterprise networks of the 1990s-2000s, and today the CT-DAWAN-MIB download is mainly sought by those maintaining or documenting this older Cabletron/Enterasys hardware.

IPNetwork Monitor allows you to monitor SNMP objects defined in CT-DAWAN-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

Cabletron/Enterasys WAN router or multiservice switch

Monitoring Examples

An administrator would typically poll a DAWAN interface table (analogous to ctDawanIfTable/ctDawanIfEntry) to check the administrative and operational state of each WAN port, correlating it with the standard ifOperStatus to detect a down WAN link. Because the source module description and object list were not available for this MIB, exact object names cannot be confirmed, so integration should be validated directly against the vendor's ASN.1 source before building polling scripts. In practice such WAN interface MIBs are used to alert when a leased-line or serial WAN circuit drops, prompting investigation of physical layer or carrier issues.

What Can Be Monitored

WAN interface administrative status
WAN interface operational status
interface configuration parameters
link state changes

INT ctDAWanDeviceIfIndex	1.3.6.1.4.1.52.4497.16.2.1.2	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.
GAU ctDAWanDeviceSessionID	1.3.6.1.4.1.52.4497.16.2.1.3	Gauge	read-only	This is the unique identifier of the last session when a wan device was in the active state.
INT ctDAWanDeviceState	1.3.6.1.4.1.52.4497.16.2.1.4	INTEGER	read-only	This is the state of the device.
STR ctDAWanDeviceDescr	1.3.6.1.4.1.52.4497.16.2.1.5	DisplayString	read-only	A textual string that identifies the peer device.
INT ctDAWanDeviceConnectControl	1.3.6.1.4.1.52.4497.16.2.1.6	INTEGER	read-write	This object controls the desired state of the wan device. Setting this object to connect(1) will initiate the set of actions to bring the wan device to the active state. Only set the object to connect(1) when the current value of ctDAWanDeviceState is inactive. Setting this object to disconnect(2) will initiate the set of actions to bring the wan device to the inactive state. Only set this object to disconnect(2) when the ctDAWanDeviceState is active. After setting the device to connect(1) or disconnect(2), refer to ctDAWanDeviceState to determine the state of the wan device. Queries to ctDAWanDeviceConnectControl return unknown results.
INT ctDAWanDeviceConnectType	1.3.6.1.4.1.52.4497.16.2.1.7	INTEGER	read-only	This specifies the type of the wan connection.

TIM ctDAWanDeviceConnectTime	1.3.6.1.4.1.52.4497.16.2.1.19	TimeStamp	read-only	The value of sysUpTime at the time when the device entered its current active state. This object will be 0 if the device is currently inactive. This object will be upctDAted whenever there is a state transition to the active state.

STR ctDAWanDeviceLastDisconnectText	1.3.6.1.4.1.52.4497.16.2.1.24	DisplayString	read-only	ASCII text describing the reason for the last 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 ctDAWanDeviceLastDisconnectCause. This object will be upctDAted whenever a call is started or cleared.
