Module: DOCS-SUBMGT3-MIB
OID (symbolic): DOCS-SUBMGT3-MIB::docsSubmgt3CpeCtrlLearnable
OID (numeric): 1.3.6.1.4.1.4491.2.1.10.1.2.1.4
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-write
Description: This attribute controls whether the CMTS may learn (and pass traffic for) CPE IP addresses associated with a CM. If this is set to 'true', the CMTS may learn up to the CM MaxCpeIp value less any DOCSIS-provisioned entries related to this CM. The nature of the learning mechanism is not specified here. If not set through DOCSIS provisioning, this object defaults to the value of the CpeLearnableDef attribute from the Base object. Note that this attribute is only meaningful if docsSubMgtCpeControlActive is 'true' to enforce a limit in the number of CPEs learned. CPE learning is always performed for the CMTS for security reasons.
What is docsSubmgt3CpeCtrlLearnable?
This per-CM TruthValue controls whether the CMTS is allowed to learn and pass traffic for CPE IP addresses behind a specific modem, up to that modem's MaxCpeIp limit. It only matters when CpeCtrlActive is 'true' for that modem, since the CMTS always performs address learning regardless for its own security bookkeeping.
