Description: Manages fault-tolerant design (FTD) failover configuration and switchover events on BAS CMTS systems.

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 BAS-FTD-MIB?

BAS-FTD-MIB is a Broadband Access System (BAS/CMTS) MIB defining Fault-Tolerant Design (FTD) failover objects that manage redundancy switchover between active and standby control processors. It exposes configuration thresholds (eligibility/idle counter thresholds, pending-callback thresholds) alongside operational counters for table requests, updates, packets, and boot state that track the failover subsystem's activity. It is fundamentally a hardware/software redundancy health-monitoring MIB -- basFtdBootState and the various request/packet counters let an operator confirm the standby processor's synchronization state and detect stalled or excessive failover-table update activity that could signal a redundancy fault or an impending/failed switchover. It appears to be a self-contained vendor MIB specific to the BAS CMTS platform's redundancy architecture, without obvious dependence on standard DOCSIS/CMTS MIBs beyond shared enterprise conventions. It is deployed on Broadband Access System (CMTS) platforms in cable broadband headend/access networks where redundant processor failover is used for high availability. Network engineers evaluating or troubleshooting this functionality can download the BAS-FTD-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in BAS-FTD-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.

Monitoring Examples

An administrator would poll basFtdBootState to confirm the standby control processor has completed its boot/sync cycle, and watch basFtdTableRequestCounter, basFtdTableRequests, and basFtdTablePackets for abnormal growth that could indicate the standby is repeatedly re-requesting synchronization data. Comparing basFtdPendingCallbackCounter against basFtdPendingCallbackThreshold and basFtdIdleCounterThreshold against basFtdTableEligibilityCounterThreshold reveals whether the FTD subsystem is stuck below its eligibility threshold, meaning an automatic failover would not yet succeed if the active processor failed.

What Can Be Monitored

standby processor boot/sync state
failover table request/update counters
pending callback counter vs threshold
eligibility/idle counter vs threshold

How to Use in IPNetwork Monitor

Example using basFtdTableEligibilityCounter OID:

Select a Broadband Access Systems (BAS) CMT (legacy) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type basFtdTableEligibilityCounter into the Find box to locate it in the OID tree, then select it and click OK. It reports the count of the FTD heartbeat timeouts since receiving a table request, i.e. an eligibility cycle. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
