Description: Extends DOCSIS cable interface management with additional objects beyond the base DOCS-IF-MIB.
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 DOCS-IF-EXT-MIB?
DOCS-IF-EXT-MIB is an IETF IPCDN Working Group standard MIB extending RFC 2670's DOCS-IF-MIB with DOCSIS-capability objects. Its objects cover the DOCSIS capability level supported, the current operating mode, and a CMTS-CM-status extension table (per-cable-modem DOCSIS mode). As a status MIB it lets an administrator confirm which DOCSIS version a cable modem or CMTS port is negotiating on a DOCSIS cable-access network. It is deployed on DOCSIS cable modems and CMTS equipment. Engineers implementing or auditing this functionality typically reference the DOCS-IF-EXT-MIB RFC/standard documentation for the authoritative specification.
IPNetwork Monitor allows you to monitor SNMP objects defined in DOCS-IF-EXT-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
- DOCSIS cable modems and CMTS equipment
Monitoring Examples
An administrator checks docsIfCmtsCmStatusDocsisMode to confirm which DOCSIS version a cable modem negotiated with the CMTS.
What Can Be Monitored
- negotiated DOCSIS capability/operating mode

RFC description
Extension to DOCSIS cable modem interface MIB providing CMTS cable modem status and DOCSIS version information.
Start monitoring DOCSIS cable modem/CMTS (capability extension, vendor-neutral IETF standard, extends RFC 2670) 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.
