Description: Manages SIAE MICROELETTRONICA microwave radio link loss forwarding configuration and trigger state.

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 SIAE-LLF-MIB?

SIAE-LLF-MIB implements Link Loss Forwarding (LLF) management for SIAE MICROELETTRONICA microwave radio equipment, a feature that propagates a detected link failure on one interface to another (commonly used to trigger Ethernet link-down signaling when a radio hop fails). It belongs to the fault-management/resiliency category within microwave transmission technology. Its monitoring value centers on fault/software status: whether LLF is enabled, what condition triggers it, and its current trigger state, which tells an operator whether a downstream failure was correctly propagated to protect upper-layer protocols like spanning tree or routing. It is a feature-specific companion to SIAE's broader radio and configuration-management MIBs rather than a standalone standard. It is deployed on SIAE microwave radio links in cellular backhaul and enterprise point-to-point networks where fast failure propagation matters. Engineers can download the SIAE-LLF-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in SIAE-LLF-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 operator would poll the LLF enable/configuration objects to confirm the feature is armed on a given radio link, then watch the trigger-state object to see if LLF has fired, which would explain why an adjacent Ethernet switch reported its port going down. Correlating an LLF trigger event with the corresponding radio link's receive power or alarm status (from companion SIAE MIBs) helps distinguish a genuine RF fade from a configuration error. This is primarily an event/state-driven monitoring point rather than a rich statistics table.

OIDs

OID symbolic	OID numeric	Type	Access	Description
llf	1.3.6.1.4.1.3373.1103.85			SIAE's Link Loss Forwarding MIB.
INT llfMibVersion	1.3.6.1.4.1.3373.1103.85.1	INTEGER	read-only	Numerical version of this module. The string version of this MIB have the following format: XX.YY.ZZ so, for example, the value 1 should be interpreted as 00.00.01 and the value 10001 should be interpreted as 01.00.01.
llfTable	1.3.6.1.4.1.3373.1103.85.2		not-accessible	Table with SIAE's LLF entries.
llfEntry	1.3.6.1.4.1.3373.1103.85.2.1		not-accessible	SIAE's LLF entry.
NUM llfIndex	1.3.6.1.4.1.3373.1103.85.2.1.1	InterfaceIndex	not-accessible	A unique value, greater than zero, for each interface supporting LLF. This object is identical to the ifIndex of the standard MIB-2 ifTable.
INT llfEnable	1.3.6.1.4.1.3373.1103.85.2.1.2	INTEGER	read-create	On interfaces supporting LLF, this object is used to disable or enable LLF towards local LAN interfaces.
INT llfUnidirectionalFault	1.3.6.1.4.1.3373.1103.85.2.1.3	INTEGER	read-create	When enable is set, a local link fault causes LLF on both local and remote interfaces.
INT llfDelayTime	1.3.6.1.4.1.3373.1103.85.2.1.4	INTEGER	read-create	The LLF delay time specifies the time interval (in seconds) to wait for to actuate or to remove the Link Loss Forwarding condition.
INT llfProtectionMode	1.3.6.1.4.1.3373.1103.85.2.1.5	INTEGER	read-create	When protection mode is enabled, LLF alarm is issued only when all radio links or circuits connected to interface are alarmed.
