Nortel-Magellan-Passport-ExtensionsMIB

Description: Provides Nortel Magellan Passport platform extension objects for custom feature 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.

This Nortel Magellan Passport module provides a generic 'extensions' framework for the Passport platform, defining an extension interface table (extensionIfTable) used to attach custom or feature-specific configuration data to interfaces without requiring a dedicated MIB per feature. It is largely a structural/framework module, exposing conformance-style groups (extensionsGroup, extensionsGroupBC, extensionsGroupBC02, extensionsGroupBC02A) that appear to represent backward-compatibility group revisions rather than a rich set of runtime telemetry objects. Its role in monitoring is indirect: rather than exposing hardware/software status itself, it provides the extensibility mechanism other Passport feature MIBs rely on to associate extra data with an interface, so its relevance is really about whether extension rows exist and are correctly associated with the expected interfaces. It is tightly coupled to the rest of the Magellan Passport MIB suite, since its extension table is designed to be referenced/extended by other Passport component MIBs. It was deployed as an underlying infrastructure module within Nortel Magellan Passport switch management systems rather than being monitored directly by operators in isolation. Engineers can download the Nortel-Magellan-Passport-ExtensionsMIB file directly to load it into their MIB browser.

Given the sample objects available (extensionIfTable/extensionIfEntry and several extensionsGroup* conformance groups), this module appears oriented toward providing an extensible per-interface data-attachment mechanism and structural conformance groupings rather than exposing standalone runtime counters. An administrator would typically encounter extensionIfTable indirectly, via another Passport feature MIB that references it to attach extension attributes to a specific interface, rather than polling it directly for a monitoring value.

Provides enterprise extensions to standard MIB ifTable for Nortel Magellan network management.
