Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is AIILINKTABLE-MIB?

AIILINKTABLE-MIB is a vendor MIB for AI-series WAN access devices defining a single link table used to enumerate and describe WAN/data links configured on the device. It exposes per-link configuration attributes: link type, description, and the mapping between a logical link and up to several underlying physical/logical interface indexes (aiLinkIfIndex1-4, aiLinkPhysIf). Because it ties link entries back to ifIndex values, it supports monitoring the operational mapping of WAN links to physical interfaces, letting an admin verify link configuration is consistent with the underlying interface layer, though it stops short of exposing deep hardware health metrics like temperature or power. It builds on the standard IF-MIB ifIndex convention for interface correlation, and includes its own conformance group and compliance statements. It is typically deployed on WAN access or multiplexer devices where several physical/logical channels are bundled or cross-referenced under named links. Engineers can download the AIILINKTABLE-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in AIILINKTABLE-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 admin would poll aiLinkTable/aiLinkEntry indexed by aiLinkIndex to enumerate configured links, reading aiLinkType and aiLinkDescr to identify each link's purpose, and aiLinkIfIndex/aiLinkIfIndex1-4 plus aiLinkPhysIf to confirm which physical interfaces back a given link. A mismatch between an expected aiLinkType and the actual bound aiLinkPhysIf, or a link entry pointing to an ifIndex that is administratively down, would reveal a misconfigured or failed WAN link.

OIDs

OID symbolic	OID numeric	Type	Access	Description
aii	1.3.6.1.4.1.539
aiSLC2	1.3.6.1.4.1.539.16
aiLink	1.3.6.1.4.1.539.16.2			The MIB module for the link table.
aiLinkTable	1.3.6.1.4.1.539.16.2.1		not-accessible	Entries define links in the system. Each link consists of a physical interface associated with one or more network interfaces. That is, it is the intention of this table to define the protocol stacks in use on an AII SLC.
aiLinkEntry	1.3.6.1.4.1.539.16.2.1.1		not-accessible	Entries of aiLinkTable.
NUM aiLinkIndex	1.3.6.1.4.1.539.16.2.1.1.1	PositiveInteger	read-only	A value that distinguishes this entry from another entry. Entries in this table are referenced from other objects which identify links.
AII aiLinkType	1.3.6.1.4.1.539.16.2.1.1.2	AIIifType	read-write	A value that distinguishes, in general, what kind of link this is. Examples include propPointToPointSerial(22), -- proprietary serial x25ple(40) and frameRelay(32), -- DTE only
STR aiLinkDescr	1.3.6.1.4.1.539.16.2.1.1.3	DisplayString	read-write	A description of the type of link that this is.
IFI aiLinkIfIndex	1.3.6.1.4.1.539.16.2.1.1.4	IfIndexType	read-only	The index into the interfaces group of MIB-II, which defines what type of interface this link is. This definition describes a protocol stack in only the most general way. The interface which appears here may have other interfaces stacked beneath it which are also in the interface table.
IFI aiLinkIfIndex1	1.3.6.1.4.1.539.16.2.1.1.5	IfIndexType	read-only	The index into the interfaces group of MIB-II, which defines what type of interface is at the bottom of this link (stack).
IFI aiLinkIfIndex2	1.3.6.1.4.1.539.16.2.1.1.6	IfIndexType	read-only	The index into the interfaces group of MIB-II, which defines what type of interface sits on top of and talks to the interface defined by aiLinkIfIndex1
IFI aiLinkIfIndex3	1.3.6.1.4.1.539.16.2.1.1.7	IfIndexType	read-only	The index into the interfaces group of MIB-II, which defines what type of interface sits on top of and talks to the interface defined by aiLinkIfIndex2
IFI aiLinkIfIndex4	1.3.6.1.4.1.539.16.2.1.1.8	IfIndexType	read-only	The index into the interfaces group of MIB-II, which defines what type of interface sits on top of and talks to the interface defined by aiLinkIfIndex3.
INT aiLinkPhysIf	1.3.6.1.4.1.539.16.2.1.1.9	INTEGER	read-write	The physical interface to be used for this link.
aiLinkX25Table	1.3.6.1.4.1.539.16.2.2		not-accessible	Entries define additional X.25 parameters not covered in the standard MIB. These parameters are applied on a per link basis for the links in the system. This table contains two entries for each of the x25 links of the card. These correspond to the Administrative and Operating values of the MIB objects. The first half of the table, contains the Administrative values for each link; they will take effect the next time the corresponding link is initialized. The second group reports the parameters currently in effect for the links; these are read-only.
aiLinkX25Entry	1.3.6.1.4.1.539.16.2.2.1		not-accessible	Entries of aiLinkX25Table.
NUM aiLinkX25Index	1.3.6.1.4.1.539.16.2.2.1.1	PositiveInteger	read-only	A value that distinguishes this entry from another entry. Entries in this table are referenced from other objects which identify links.
INT aiLinkX25Negotiation	1.3.6.1.4.1.539.16.2.2.1.2	INTEGER	read-write	This entry determines whether or not Facility Negotiation is enabled for circuits established on this X.25 link. When disabled, the circuits will still respond to X.25 facility negotiation requests, but they will not initiate a negotiation session.
INT aiLinkX25LinkMode	1.3.6.1.4.1.539.16.2.2.1.3	INTEGER	read-write	This entry determines whether link behaves as a normal X.25 link or a BX.25-style passive link, or BX.25-style extended passive link.
