What Is Nortel-MsCarrier-MscPassport-FrameRelayNniMIB?

This Nortel MsCarrier MscPassport MIB provides SNMP objects for Frame Relay Network-to-Network Interface (NNI) links, which interconnect Frame Relay switches/networks (as opposed to user-facing UNI links) on the Passport platform. It exposes provisioning tables including customer identifier (CID) data for tracking which customer/service a given NNI link serves, plus a state table for the operational status of NNI components. Monitoring centers on confirming NNI link components are provisioned and active, and on tracking their operational state as a proxy for inter-network link health, since the sampled objects do not include throughput or error counters. It relies on the Frame Relay Forum's NNI signaling specification and shares the common Passport row-status/component provisioning model with sibling Frame Relay MIBs in this family. It is used by carriers interconnecting Frame Relay networks or switches via NNI trunks on Nortel MsCarrier Passport equipment. Network engineers evaluating or troubleshooting this functionality can download the Nortel-MsCarrier-MscPassport-FrameRelayNniMIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Nortel-MsCarrier-MscPassport-FrameRelayNniMIB. 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.

Supported Devices

  • Nortel MsCarrier MscPassport switch

Monitoring Examples

An operator would poll mscFrNniRowStatusTable/mscFrNniRowStatusEntry to verify an NNI link component is active, then check mscFrNniStateTable/mscFrNniStateEntry for its operational status and mscFrNniCidDataTable for the mscFrNniCustomerIdentifier tied to that link. If inter-carrier Frame Relay traffic stops flowing, the first checks are whether the NNI component's row status and operational state both indicate "up," and whether the customer identifier binding (mscFrNniDna) still matches provisioning records. No traffic counters are exposed, so this is primarily a provisioning/state health check.

What Can Be Monitored

  • NNI link row status
  • NNI operational state
  • customer identifier binding
  • NNI DNA/addressing data
