Category: ATM, Vendor: Nortel

Description: Manages system configuration parameters and device settings on Nortel Centillion ATM switch platforms.

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.

What Is CENTILLION-CONFIG-MIB?

CENTILLION-CONFIG-MIB is a Nortel/Bay Networks vendor MIB, anchored under the CENTILLION-ROOT-MIB sysConfig branch, that manages system-level configuration and maintenance state on Centillion ATM switch platforms. It exposes system image inventory in sysImgTable (sysImgVer, sysImgStatus indicating other/good/bad per stored image), MCP (Multiprocessor Control Processor) redundancy state in sysMcpRedundTable (sysMcpRedundPriority, sysMcpRedundType distinguishing primary/secondary/switching roles, sysMcpRedundOperState), a routing-information-field table (rifTable) for source-route bridging, and SNMP trap-receiver configuration in sysSNMPTrapIPReceiverTable. This surfaces both the software/firmware inventory and the high-availability control-plane state of a chassis, important for confirming a redundant MCP module is in the expected role and that stored system images are valid before a failover or reload. It depends on CENTILLION-ROOT-MIB for shared textual conventions (StatusIndicator, MacAddress) and the sysConfig OID anchor, and is deployed on Nortel/Bay Networks Centillion ATM switch chassis -- administrators can download the CENTILLION-CONFIG-MIB file to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CENTILLION-CONFIG-MIB. 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/Bay Networks Centillion ATM switch chassis

Monitoring Examples

An operator polls sysMcpRedundTable to confirm the standby MCP reports sysMcpRedundType as secondary with a healthy sysMcpRedundOperState, and checks sysImgStatus in sysImgTable for the loaded image; an MCP entry unexpectedly reporting switching or an image status of bad would indicate an in-progress or failed MCP failover.

What Can Be Monitored

  • system image version and validity status
  • MCP redundancy priority, type, and operational state
  • MCP configuration/sync status
  • source-route bridging RIF table entries
  • SNMP trap receiver configuration
