What Is ATT-CNM-SYSTEM-MIB?

ATT-CNM-SYSTEM-MIB is a MIB from AT&T supporting its Customer Network Management (CNM) service offering, providing system-level managed objects for customer-facing visibility into AT&T-managed network equipment. It exposes general system/inventory objects such as device identification, contact information, and overall operational status, giving customers a standardized view of the health of equipment AT&T manages on their behalf. Its monitoring emphasis is on system-level software/operational status rather than granular hardware sensors — essentially a high-level "is this managed element up and correctly identified" check, akin to a customer-facing sysDescr/sysContact/sysUpTime style view layered with AT&T CNM semantics. It parallels and likely builds on standard SNMPv2-MIB system-group conventions, tailored for AT&T's managed-service reporting model. It is deployed on customer premises equipment and network elements that are part of AT&T's Customer Network Management managed-service offerings. Engineers can download the ATT-CNM-SYSTEM-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ATT-CNM-SYSTEM-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

AT&T-managed customer premises equipment / network element (Customer Network Management service)

Monitoring Examples

A customer or AT&T operations engineer would poll system inventory and contact objects to confirm equipment identification details are current, and check the operational status object to verify a managed element is reporting healthy rather than in a fault or offline condition. An operational status object unexpectedly showing a fault state while the device otherwise responds to SNMP would indicate a service-affecting condition AT&T's CNM system needs to escalate.

What Can Be Monitored

OIDs

OID symbolic	OID numeric	Type	Access	Description
att_2	1.3.6.1.4.1.74
att_products	1.3.6.1.4.1.74.1
att_cnmAgent	1.3.6.1.4.1.74.1.9
att_mgmt	1.3.6.1.4.1.74.2
att_cnm	1.3.6.1.4.1.74.2.15
att_cnm_system	1.3.6.1.4.1.74.2.15.1
STR attCNMsysDescr	1.3.6.1.4.1.74.2.15.1.1	DisplayString	read-only	A printable ASCII string that is a textual description of this system. This value typically includes the full name and version identification of the system. This identification can be used to distinguish this system from other systems for the purpose of fault identification/isolation, trouble reporting etc.
OID attCNMsysObjectID	1.3.6.1.4.1.74.2.15.1.2	OBJECT IDENTIFIER	read-only	The vendor's authoritative identification of the network management subsystem contained in the entity. This value is allocated within the SMI enterprises subtree (1.3.6.1.4.1) and provides an easy and unambiguous means for determining `what kind of box' is being managed. For example, if vendor `Flintstones, Inc.' was assigned the subtree 1.3.6.1.4.1.4242, it could assign the identifier 1.3.6.1.4.1.4242.1.1 to its `Fred Router'. This identification can be used to distinguish this system from other systems.
TIK attCNMsysUpTime	1.3.6.1.4.1.74.2.15.1.3	TimeTicks	read-only	The time (in hundredths of a second) since the SNMP interface portion of the system was last re-initialized. This value may be used to determine the last time this system was re-initialized (i.e. the most recent reset for the SNMP interface).
STR attCNMsysContact	1.3.6.1.4.1.74.2.15.1.4	DisplayString	read-only	The textual identification of the contact person(s) or organization(s) for this system, along with information on how to contact them.
STR attCNMsysName	1.3.6.1.4.1.74.2.15.1.5	DisplayString	read-only	An administratively-assigned name for this system. By convention, this is the system's fully-qualified domain name. This variable distinguishes this system from other systems in the network.
STR attCNMsysLocation	1.3.6.1.4.1.74.2.15.1.6	DisplayString	read-only	The physical location of this system. This variable distinguishes this system from others for location purposes.
INT attCNMsysServices	1.3.6.1.4.1.74.2.15.1.7	INTEGER	read-only	A value which indicates the set of services offered by the managed network elements. The value is a sum. This sum initially takes the value zero, Then, for each layer, L, in the range 1 through 7, that this node performs transactions for, 2 raised to (L - 1) is added to the sum. For example, a node which performs primarily routing functions would have a value of 4 (2^(3-1)). In contrast, a node which is a host offering application services would have a value of 72 (2^(4-1) + 2^(7-1)). Note that in the context of the Internet suite of protocols, values should be calculated accordingly: layer functionality 1 physical (e.g., repeaters) 2 datalink/subnetwork (e.g., bridges) 3 internet (e.g., IP gateways) 4 end-to-end (e.g., IP hosts) 7 applications (e.g., mail relays) For systems including OSI protocols, layers 5 and 6 may also be counted. For SMDS and Frame Relay Service, this agent will return a value of 2 which indicates that the managed network elements offer a subnetwork-level service.
att_cnm_interfaces	1.3.6.1.4.1.74.2.15.2
INT attCNMifNumber	1.3.6.1.4.1.74.2.15.2.1	INTEGER	read-only	The number of network interfaces (regardless of their current state) that can be managed by a specific subscriber.
attCNMifConfigTable	1.3.6.1.4.1.74.2.15.2.2		not-accessible	A list of entries containing general information for all interfaces managed by this system.
attCNMifConfigEntry	1.3.6.1.4.1.74.2.15.2.2.1		not-accessible	An entry containing general configuration information for a particular interface.
INT attCNMifConfigIndex	1.3.6.1.4.1.74.2.15.2.2.1.1	INTEGER	read-only	A unique value assigned to each interface by the administrator of this system.
STR attCNMifDescr	1.3.6.1.4.1.74.2.15.2.2.1.2	DisplayString	read-only	A textual string containing information about this interface. This string typically contains the name of the service provider, the service offered by this interface, and the name of the subscriber to this interface.
INT attCNMifType	1.3.6.1.4.1.74.2.15.2.2.1.3	INTEGER	read-only	The type of interface being managed.
INT attCNMifMtu	1.3.6.1.4.1.74.2.15.2.2.1.4	INTEGER	read-only	The size of the largest data PDU which can be sent/received on the interface, specified in octets. For SMDS, this value represents the maximum L3 PDU size that is supported on this interface.
GAU attCNMifSpeed	1.3.6.1.4.1.74.2.15.2.2.1.5	Gauge	read-only	An estimate of the interface's current nominal bandwidth in bits per second.
STR attCNMifContact	1.3.6.1.4.1.74.2.15.2.2.1.6	DisplayString	read-only	A printable ASCII string that identifies the contact person(s) or organization(s) responsible for support of this interface.
STR attCNMifLocation	1.3.6.1.4.1.74.2.15.2.2.1.7	DisplayString	read-only	A printable ASCII string that identifies the physical location of the switching system that terminates this interface.
STR attCNMifSubscriber	1.3.6.1.4.1.74.2.15.2.2.1.8	DisplayString	read-only	A printable ASCII string that identifies the contact person(s) or organization(s) that have subscribed to this interface.
attCNMifStatusTable	1.3.6.1.4.1.74.2.15.2.3		not-accessible	A list of entries containing status information for all interfaces managed by this system.
attCNMifStatusEntry	1.3.6.1.4.1.74.2.15.2.3.1		not-accessible	An entry containing status information for a particular interface.
INT attCNMifStatusIndex	1.3.6.1.4.1.74.2.15.2.3.1.1	INTEGER	read-only	A unique value for each interface. The interface identified by a particular value of this index is the same interface as identified by the same value of an attCNMifConfigIndex object instance.
INT attCNMifAdminStatus	1.3.6.1.4.1.74.2.15.2.3.1.2	INTEGER	read-only	The desired state of this interface.
INT attCNMifOperStatus	1.3.6.1.4.1.74.2.15.2.3.1.3	INTEGER	read-only	The current operational state of this interface.
