What Is SIAE-MAB-MIB?

SIAE-MAB-MIB is a vendor MIB from SIAE MICROELETTRONICA, an Italian manufacturer of microwave radio backhaul equipment, covering the Microwave Adaptive Bandwidth (MAB) feature jointly developed with Cisco. It exposes configuration-oriented data for the MW Capacity Management (MCM) feature, including MAC address bypass settings for transparent Ethernet bridging across microwave hops and Link ID TLV parameters used to identify each radio segment. Rather than hardware sensors, this MIB is used mainly to confirm that software-level bridging/bypass configuration on each radio node matches the intended network design, so monitoring here means verifying configuration state and feature enablement rather than temperature or power metrics. It has an implicit dependency on other SIAE microwave MIBs (such as unit-type and radio-link MIBs) and on standard bridge/Ethernet MIB conventions for MAC addressing. It is typically deployed on SIAE microwave radio links used for mobile backhaul, often in mixed SIAE/Cisco network topologies, where SIAE-MAB-MIB SNMP monitoring verifies bypass and Link ID configuration across each hop.

IPNetwork Monitor allows you to monitor SNMP objects defined in SIAE-MAB-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

No specific object names were provided in the sample data for this module, so a concrete object-level scenario cannot be grounded reliably; based on the module description, it would plausibly expose per-interface MAC bypass enable/disable settings and Link ID TLV identifiers for each hop in an MCM-enabled microwave chain. An administrator would poll these settings to confirm bypass mode is consistently applied across all radios in a link and that Link ID TLVs uniquely identify each segment, catching misconfiguration that could break QoS-optimized MCM operation under adverse radio conditions.

What Can Be Monitored

MAC address bypass mode enable/disable
Link ID TLV configuration per radio link
MW Capacity Management (MCM) feature state
transparent Ethernet bridging configuration
