The Event Notification MIB is an extension of the
CABLE DEVICE MIB defined in RFC 2669. It defines various
trap objects for both cable modem and cable modem
termination systems. Two groups of SNMP notification
objects are defined. One group is for notifying cable
modem events and one group for notifying cable modem
termination system events. Common to all CM
notification objects (traps) is that their OBJECTS
statements contain information about the event priority,
the event Id, the event message body, the CM DOCSIS
capability, the CM DOCSIS QOS level, the CM DOCSIS
upstream modulation type, the cable interface MAC
address of the cable modem and the cable card MAC address
of the CMTS to which the modem is connected.
These objects are docsDevEvLevel, docsDevId,
docsDevEvText, docsIfDocsisBaseCapability,
docsIfCmStatusDocsisOperMode, docsIfCmStatusModulationType
ifPhysAddress and docsIfCmCmtsAddress. The values of
docsDevEvLevel, docsDevId, and docsDevEvText are from the
entry which logs this event in the docsDevEventTable,
which is defined in DOCS-CABLE-DEVICE-MIB of RFC 2669. The
docsIfDocsisBaseCapability, docsIfCmStatusDocsisOperMode,
and docsIfCmStatusModulationType are defined in the
DOCS-IF-MIB. The ifPhysAddress value is the MAC address
Of the cable interface of this cable modem. The
docsIfCmCmtsAddress specifies the MAC address of the CMTS
(if there is a cable card/ interface in the CMTS, then it
is actually the cable interface interface MAC address to
which the CM is connected). Individual CM trap may
contain additional objects to provide necessary
information.
Common to all CMTS notification objects (traps) is that
their OBJECTS statements contain information about the
event priority, the event Id, the event message body,
the connected CM DOCSIS QOS status, the connected CM
DOCSIS modulation type, the CM cable interface MAC
address, the CMTS DOCSIS capability, and the CMTS MAC
address.
These objects are docsDevEvLevel, docsDevId,
docsDevEvText, docsIfCmtsCmStatusDocsisRegMode,
docsIfCmtsCmStatusModulationType,
docsIfCmtsCmStatusMacAddress,
docsIfDocsisBaseCapability, and ifPhysAddress. The values
of docsDevEvLevel, docsDevId, and docsDevEvText are
similar to those in CM traps. The values of
docsIfCmtsCmStatusDocsisRegMode,
docsIfCmtsCmStatusModulationType, and
docsIfCmtsCmStatusMacAddress are from the
docsIfCmtsCmStatusEntry (defined in DOCS-IF-MIB)
corresponding
to a connected CM. The docsIfDocsisBaseCapability
indicates the CMTS DOCSIS capability. The ifPhysAddress
value is the CMTS MAC address (if there is a cable card/
interface in the CMTS, then it is actually the MAC
address of the cable interface which connected to the CM).
