What Is Nortel-MsCarrier-MscPassport-FrameRelayUniMIB?

Nortel-MsCarrier-MscPassport-FrameRelayUniMIB provides SNMP objects for Frame Relay UNI (User-Network Interface) management on Nortel MsCarrier MscPassport switches, covering the interface between a customer's Frame Relay access equipment and the carrier network. It exposes RowStatus provisioning tables, customer identifier association data, and an interface state table (mscFrUniStateTable) reflecting the UNI's operational condition. The state table is the MIB's key monitoring asset, since it reveals whether a Frame Relay UNI interface is up, down, or in a degraded operational state, giving direct visibility into physical/link-layer hardware health at the customer access point. It follows the RowStatus/component conventions of the broader MsCarrier MscPassport MIB suite and implements Frame Relay Forum UNI specifications. It is deployed on MscPassport switches providing Frame Relay access services to enterprise or carrier customers. Engineers can download the Nortel-MsCarrier-MscPassport-FrameRelayUniMIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Nortel-MsCarrier-MscPassport-FrameRelayUniMIB. 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 Passport switch (Frame Relay access)

Monitoring Examples

An operator queries mscFrUniStateTable/mscFrUniStateEntry for a given mscFrUniIndex to check whether the UNI interface is reporting an up or down operational state, which is the first thing checked when a customer reports a Frame Relay outage. mscFrUniCidDataTable/mscFrUniCidDataEntry with mscFrUniCustomerIdentifier maps the interface to the affected customer, and mscFrUniRowStatusTable/mscFrUniRowStatusEntry confirms the underlying UNI component is provisioned and active.

What Can Be Monitored

  • Frame Relay UNI operational state
  • customer identifier per UNI
  • UNI provisioning parameters
  • component row status
  • storage type
