This is the MIB module for the Cisco specific extension objects of Data Over Cable Service, Radio Frequency interface. There is a standard MIB for Data-Over-Cable Service Interface Specifications (DOCSIS) and in Cisco, it is called DOCS-IF-MIB. Besides the objects in DOCS-IF-MIB, this MIB module contains the extension objects to manage the Cable Modem Termination Systems (CMTS). This MIB module includes objects for the scheduler that supports Quality of Service (QoS) of MCNS/DOCSIS compliant Radio Frequency (RF) interfaces in Cable Modem Termination Systems (CMTS). And the purpose is to let users configure attributes of the schedulers in order to ensure the Quality of Service and fairness for modem requests according to users' business needs. Also this MIB shows various states of the schedulers for users to monitor of the schedulers' current status. This MIB module also includes connection status objects for cable modems and Customer Premise Equipment (CPE) and the purpose is to let users easily get the connection status and manage access group information about cable modems and CPE. This MIB module also includes objects for upstream configuration for automated spectrum management in order to mitigate upstream impairment. This MIB module also includes objects to keep count of the total # of modems, # of registered and # of active modems on the mac interface as well as each upstream.
