Description: Provides Cisco-specific extensions for DS0 bundle management, supplementing standard DS0 bundle objects with additional configuration.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is CISCO-DS0BUNDLE-EXT-MIB?

CISCO-DS0BUNDLE-EXT-MIB provides Cisco-specific extensions to the IETF draft DS0 Bundle MIB, supplementing the standard objects used to manage bundles of DS0 timeslots (fractional T1/E1 channels) with additional Cisco configuration and information objects. The data it exposes is primarily configuration and informational status for DS0 bundle groupings, extending what the base IETF MIB tracks about timeslot bundling for WAN interfaces. As a configuration/status MIB it lets an administrator verify Cisco-specific bundle attributes are correctly applied on top of the standard bundle definition, supporting proper channel-group provisioning on fractional T1/E1 interfaces. It explicitly depends on and supplements the IETF draft ds0Bundle MIB, meaning it cannot be interpreted without that base module's bundle table and index structure. It is typically deployed on Cisco routers with channelized T1/E1 WAN interfaces where fractional bandwidth is allocated via DS0 bundles. Engineers can download the CISCO-DS0BUNDLE-EXT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-DS0BUNDLE-EXT-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 cross-references entries under cdsx0BundleConfig and cdsx0BundleInfo against the base ds0Bundle MIB's bundle index to confirm Cisco-specific configuration attributes are correctly applied to a given channel group. Because this MIB only supplements the standard bundle table rather than replacing it, an operator would typically poll the base ds0BundleTable for the timeslot list and status, then check ciscoDs0BundleExtMIBObjects for any Cisco-added configuration flags affecting that same bundle. A mismatch between the expected Cisco extension settings and actual channel-group behavior would point to a provisioning error on the fractional T1/E1 interface.

OIDs

OID symbolic	OID numeric	Type	Access	Description
ciscoDs0BundleExtMIB	1.3.6.1.4.1.9.10.33			The MIB module for managing DS0 Bundles. This MIB contains additional objects to supplement the the IETF draft ds0Bundle MIB.
ciscoDs0BundleExtMIBObjects	1.3.6.1.4.1.9.10.33.1
cdsx0BundleConfig	1.3.6.1.4.1.9.10.33.1.1
cdsx0BundleExtTable	1.3.6.1.4.1.9.10.33.1.1.1		not-accessible	This table is used to supplement the dsx0BundleTable.
cdsx0BundleExtEntry	1.3.6.1.4.1.9.10.33.1.1.1.1		not-accessible	Contains objects to configure a ds0Bundle. The values of objects cdsx0BundleExtDs1Index and cdsx0BundleExtChannelMap must be specified for the associated row to become active.
NUM cdsx0BundleExtDs1Index	1.3.6.1.4.1.9.10.33.1.1.1.1.1	InterfaceIndex	read-write	The ifIndex of the DS1 line containing the ds0 timeslots in this bundle. The ds0 bundle interface is layered on top of the DS1 line. This layering is represented in the ifStackTable. This object is not instantiated until the value is specified. The value may be set only when the ds0 bundle is created.
DS0 cdsx0BundleExtChannelMap	1.3.6.1.4.1.9.10.33.1.1.1.1.2	Ds0ChannelList	read-write	A list of ds0 timeslots that comprise this ds0 bundle. This object is not instantiated until the value is specified. The value may be set only when the ds0 bundle is created.
INT cdsx0BundleExtEncapType	1.3.6.1.4.1.9.10.33.1.1.1.1.3	INTEGER	read-write	The type of encapsulation for this bundle. A ds0 bundle is a logical serial port. Setting this object defines the type of the serial port. If not specified, the value is none(1), indicating that the encapsulation type on this serial port is not defined. If the value is changed to atmFuni(2), the agent will create an entry in the ifTable with ifType equal to atmFuni(106). If the value is changed to frameRelay(3), the agent will create an entry in the ifTable with ifType equal to frameRelayService(44). The new atmFuni or frameRelayService interface is layered on top of the ds0 bundle interface. This layering will be represented in the ifStackTable. The value of this object can be changed only if the ifOperStatus of the associated atmFuni or frameRelayService interface is down. When the value is changed, the agent removes all existing connections on the interface, and also deletes the ifEntry that was created because of the previous value.
INT cdsx0BundleExtChannelRate	1.3.6.1.4.1.9.10.33.1.1.1.1.4	INTEGER	read-write	The data rate of each ds0 in this bundle. rate56 - 56kb/s rate64 - 64kb/s For ds0's on a T1 line, the value should be rate56(1) if 'robbed bit' signaling is used, and rate64(2) if clear channel signaling is used. For ds0's on a E1 line, the value should always be rate64(2). The value can be set only when the entry is created.
cdsx0BundleInfo	1.3.6.1.4.1.9.10.33.1.2
cdsx0BundleUseTable	1.3.6.1.4.1.9.10.33.1.2.1		not-accessible	Shows the ds0 timeslots that are currently in use (i.e., part of a ds0 bundle) on channelized DS1 lines. There is an entry in this table for each channelized DS1 line which has an ifEntry.
cdsx0BundleUseEntry	1.3.6.1.4.1.9.10.33.1.2.1.1		not-accessible	Contains the ds0 timeslots that are currently part of various ds0 bundles on the DS1 line identified by the ifIndex. This information can be useful for an NMS when creating new ds0 bundles on this DS1.
DS0 cdsx0BundleUseDs0Used	1.3.6.1.4.1.9.10.33.1.2.1.1.1	Ds0ChannelList	read-only	A list of ds0 timeslots on this DS1 line that are currently in use, i.e., are part of some ds0 bundle.
ciscoDs0BundleExtMIBConformance	1.3.6.1.4.1.9.10.33.3
ciscoDs0BundleExtMIBCompliances	1.3.6.1.4.1.9.10.33.3.1
ciscoDs0BundleExtMIBCompliance	1.3.6.1.4.1.9.10.33.3.1.1			The compliance statement for DS0Bundle interfaces.
ciscoDs0BundleExtMIBGroups	1.3.6.1.4.1.9.10.33.3.2
ciscoDs0BundleExtConfigGroup	1.3.6.1.4.1.9.10.33.3.2.1			A collection of objects providing the ability to configure a ds0 bundle.
ciscoDs0BundleExtInfoGroup	1.3.6.1.4.1.9.10.33.3.2.2			A collection of objects providing information about which ds0 timeslots are in ds0 bundles.
