Description: Monitors chassis, card slots, and environmental status on Cisco 6400 DSL aggregation 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 CISCO-6400-CHASSIS-MIB?

CISCO-6400-CHASSIS-MIB is a Cisco enterprise MIB for the Cisco 6400 series universal DSL access concentrator/aggregation chassis, monitoring chassis-level and card-slot hardware status plus redundancy configuration. It covers chassis/slot inventory and configuration, redundancy/auto-sync settings between main CPU cards, slot switchover control, and related environmental status. It directly supports hardware status monitoring: it tracks which line/processor cards are installed in each slot, whether configuration auto-sync (startup-config, running-config, bootvar) between redundant CPUs is enabled, and reports slot and CPU switchover events, key to detecting a failed processor card or a failed redundancy switchover. It is used alongside Cisco's standard CISCO-ENTITY-* and environmental monitor MIBs for full chassis coverage, though it is not formally dependent on them. It is deployed on Cisco 6400 DSL aggregation platforms in carrier/ISP central offices providing broadband subscriber aggregation. Engineers can download the CISCO-6400-CHASSIS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-6400-CHASSIS-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

  • Cisco 6400 series DSL access concentrator

Monitoring Examples

An admin checks c64SlotConfigTable/c64SlotConfigEntry fields such as c64SlotConfigModule1Index and c64SlotConfigStatus to confirm which module is installed and active in each slot, and watches c64MainCPUSwitchOver and c64SlotSwitchOver to detect an unplanned failover between redundant CPU or line cards. c64MainCPUConfigAutoSync reveals whether startup-config/running-config are kept synchronized between the active and standby CPU, with a mismatch indicating a redundancy configuration problem. c64RedundantGroup shows which slots are grouped together for failover purposes.

What Can Be Monitored

  • slot/module inventory
  • CPU/slot switchover events
  • configuration auto-sync status
  • redundant group state
