XYLAN-CSM-VUNINNI-MIB

Description: Manages Xylan CSM virtual UNI/NNI interface configuration and signaling parameters.

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 is a vendor-specific MIB module from Xylan Corporation (a LAN/ATM switching vendor later acquired by Alcatel) for its CSM (Communication Switching Module) product line, defining configuration and signaling objects for virtual UNI (User-Network Interface) and NNI (Network-Network Interface) connections used in ATM/LAN-emulation networking. It exposes configuration-oriented data covering virtual interface provisioning, signaling parameters, and interface-to-network mapping rather than raw performance counters. Because no module description or object list is available for this entry, its practical value is inferred from its name: it would track the operational and administrative state of virtual UNI/NNI links, serving as an indirect proxy for switch connectivity health rather than deep hardware diagnostics like CPU, memory, or temperature. It likely relies on standard SNMPv2-SMI/SNMPv2-TC conventions typical of enterprise switch MIBs of its era, though no explicit dependency is confirmed in the available text. It would typically be deployed by operators managing legacy Xylan/Alcatel ATM-based campus or WAN switches to verify that provisioned virtual interfaces are established and signaling correctly. Network engineers evaluating or troubleshooting this functionality can download the XYLAN-CSM-VUNINNI-MIB file directly to load it into their MIB browser.

No specific object or table names are available for this module in the source excerpt, so a precise polling scenario cannot be grounded in real identifiers. Based on the module's name and purpose, it would define configuration and status objects for virtual UNI/NNI interfaces used in ATM/LAN emulation networks, letting an operator confirm a provisioned virtual circuit is signaling correctly. A mismatch between a virtual interface's administrative and operational state would typically flag a signaling or provisioning fault requiring further diagnosis with vendor tools.
