What Is Nortel-Magellan-Passport-PorsAtmTrunksMIB?
Nortel-Magellan-Passport-PorsAtmTrunksMIB defines SNMP objects for Packet-over-Ring (PORS) ATM trunk configuration and statistics on Magellan Passport switches, covering the ATM trunks that carry traffic over a ring-topology transport network. It exposes RowStatus provisioning tables for trunk components, the underlying ATM connection association, and trunk mode configuration. Its monitoring focus is on trunk hardware/link status, since confirming a PORS ATM trunk component is active and correctly bound to its ATM connection is how operators detect a failed or misconfigured ring trunk link before it disrupts ring-wide traffic. It shares the RowStatus/component architecture of the broader Magellan Passport MIB suite and layers on ATM Forum trunking concepts within a proprietary ring transport scheme. It is deployed on Magellan Passport switches interconnected via ATM-over-ring transport in carrier backbone networks. Engineers can download the Nortel-Magellan-Passport-PorsAtmTrunksMIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in Nortel-Magellan-Passport-PorsAtmTrunksMIB. 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 Magellan Passport ATM switch (ring/PORS transport)
Monitoring Examples
An operator queries trkPaAtmRowStatusTable/trkPaAtmRowStatusEntry to verify a PORS ATM trunk component (trkPaAtmIndex) is active, and checks trkPaAtmProvTable/trkPaAtmProvEntry for the configured trkPaAtmAtmConnection and trkPaAtmMode. If ring traffic is dropping, comparing the trunk's configured mode and connection binding against expected values helps isolate whether the fault is a trunk misconfiguration or a physical ring-link hardware failure.
What Can Be Monitored
- PORS ATM trunk row status
- ATM connection binding
- trunk mode
- provisioning parameters
- storage type
