BAS-MIB

Defines the root OID hierarchy and common objects for Broadband Access Systems (BAS) CMTS MIB modules.

BAS-MIB is the root registration MIB for Broadband Access Systems, Inc. (a CMTS vendor later absorbed into other cable-industry product lines), defining the top-level OID tree for its cable modem termination system products. Beyond pure registration, it also defines a set of trap-related objects that carry chassis, slot, interface, and address context for fault notifications generated elsewhere in the product's MIB suite. It plays a real role in monitoring hardware and fault status: trap payload objects like basTrapChassis, basTrapSlot, and basTrapIf identify exactly which physical component raised an alarm, while basTrapCmtsCmMacAddress/basTrapCmtsCmIpAddress and gateway/management/craft IP objects pinpoint the affected cable modem or management interface. It underlies the broader BAS CMTS MIB family (e.g. basCudaChassMgr, basCuda10100Rs modules) that generate these notifications. It is used in cable operator headends managing Broadband Access Systems CMTS chassis via SNMP. Every trap and object emitted by the broader BAS CMTS MIB family is ultimately rooted at a BAS-MIB OID, making this module the anchor point for the entire product line's SNMP namespace.

A monitoring system receiving a chassis-related trap would inspect basTrapChassisNumber and basTrapSlot to identify which physical slot raised the alarm, and basTrapIf/basTrapLPort to pinpoint the affected line card interface. For cable-modem-specific faults, basTrapCmtsCmMacAddress, basTrapCmtsCmIpAddress, and basTrapCmtsCmGwAddress identify the specific subscriber modem involved, while basTrapMgmtOneIpAddress/basTrapMgmtTwoIpAddress and basTrapCraftIpAddress help correlate the alarm to the correct management or craft-access interface on the basProductId-identified chassis.
