Description: EXTENDED-CAPABILITIES-MIB module

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 EXTENDED-CAPABILITIES-MIB?

EXTENDED-CAPABILITIES-MIB is a vendor-neutral, standards-oriented SNMP infrastructure module that defines a framework for an SNMP agent to advertise, and for a manager to negotiate, the use of extended (non-standard or optional) SNMP protocol capabilities. Rather than exposing device data such as interfaces or hardware sensors, it exposes meta-level capability-negotiation objects describing what optional SNMP features an agent supports. Because it operates at the protocol/session layer rather than the managed-device layer, it is not used to monitor hardware or software status like uptime, temperature, or CPU load - it exists purely to let management stations and agents agree on capability extensions before other, data-bearing MIBs are polled. It has an inherent dependency on the base SNMP framework (the SNMPv3 architecture and RFC 3411 series) since capability negotiation sits directly on top of the SNMP engine. It would be deployed wherever an SNMP agent implementation wants to signal support for proprietary or draft SNMP extensions to compatible management software. Engineers can download the EXTENDED-CAPABILITIES-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in EXTENDED-CAPABILITIES-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

vendor-neutral, standards-based MIB, not tied to a specific manufacturer
any SNMP-managed network device/agent

Monitoring Examples

No sample objects were supplied for this module, and its purpose is inherently protocol/negotiation-oriented rather than data-bearing, so no concrete monitoring scenario applies; it functions more like a capability-registration mechanism than a source of pollable operational metrics.

OIDs

OID symbolic	OID numeric	Type	Access	Description
extendedCapabilitiesMib	1.3.6.1.4.1.1579.42.1.3.2			This MIB module defines a framework for advertising and negotiating the use of extended SNMP capabilities.

EXT eCapGeneral	1.3.6.1.4.1.1579.42.1.3.2.1.1	ExtendedCapabilities	read-only	The basic set of extended capabilities supported by an agent as a whole. The eCapTable can be used to override this setting for individual MIB subtrees.
eCapTable	1.3.6.1.4.1.1579.42.1.3.2.1.2		not-accessible	A table of alternative sets of extended capabilities, supported by particular MIB subtrees of the agent.
eCapEntry	1.3.6.1.4.1.1579.42.1.3.2.1.2.1		not-accessible
U32 eCapIndex	1.3.6.1.4.1.1579.42.1.3.2.1.2.1.1	Unsigned32	not-accessible	An arbitrary index into the eCapTable.
OID eCapSubtree	1.3.6.1.4.1.1579.42.1.3.2.1.2.1.2	OBJECT IDENTIFIER	read-only	The OID that identifies the root of a MIB subtree, supporting different extended capabilities to the agent as a whole.
EXT eCapSettings	1.3.6.1.4.1.1579.42.1.3.2.1.2.1.3	ExtendedCapabilities	read-only	The set of extended capabilities supported by the agent for the MIB subtree rooted at eCapSubtree. This value replaces the eCapGeneral for objects within this subtree.
eReqCapTable	1.3.6.1.4.1.1579.42.1.3.2.1.3		not-accessible	A 'pseudo-table', used to indicate which varbinds in a request should involve particular extended capabilities. This is not a conventional MIB table, and will not appear in the output of walking the agent.
eReqCapEntry	1.3.6.1.4.1.1579.42.1.3.2.1.3.1		not-accessible
U32 eReqCapIndex	1.3.6.1.4.1.1579.42.1.3.2.1.3.1.1	Unsigned32	not-accessible	The index of a particular VarBind in the request list, indicating the range of varbinds to which the specified extended capabilit(ies) should be applied.
EXT eReqCapabilities	1.3.6.1.4.1.1579.42.1.3.2.1.3.1.2	ExtendedCapabilities	read-only	The extended capabilit(ies) that should be applied to the indicated range of varbinds in the request list.
INT eReqCapRangeStart	1.3.6.1.4.1.1579.42.1.3.2.1.3.1.3	INTEGER	read-only	Indicates that the specified extended capabilit(ies) should be applied to all varbinds in the request list from the indicated varbind, up to and including the varbind indicated by the corresponding eReqCapRangeEnd (or the end of the varbind list). The value returned in the response may indicate whether this capability was supported and/or used in processing the request.
INT eReqCapRangeEnd	1.3.6.1.4.1.1579.42.1.3.2.1.3.1.4	INTEGER	read-only	Indicates that the specified extended capabilit(ies) should be applied to all varbinds in the request list up to and including the indicated varbind, starting from the varbind indicated by the corresponding eReqCapRangeStart (or the beginning of the varbind list). The value returned in the response may indicate whether this capability was supported and/or used in processing the request.
INT eReqCapVarBind	1.3.6.1.4.1.1579.42.1.3.2.1.3.1.5	INTEGER	read-only	Indicates that the specified extended capabilit(ies) should be applied to the indicated varbind. The value returned in the response may indicate whether the capability was supported and/or used in processing the request.
INT eReqCapAllBar	1.3.6.1.4.1.1579.42.1.3.2.1.3.1.6	INTEGER	read-only	Indicates that the specified extended capabilit(ies) should be applied to all varbinds in the request list except the indicated varbind(s). The value returned in the response may indicate whether the capability was supported and/or used in processing the request.
