docsSubMgtCpeControlLearnable
Module: DOCS-IETF-SUBMGT-MIB
OID (symbolic): DOCS-IETF-SUBMGT-MIB::docsSubMgtCpeControlLearnable
OID (numeric): 1.3.6.1.2.1.125.1.1.1.3
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-write
Description: Controls whether the CMTS may learn (and pass traffic for) CPE IP addresses associated with a cable modem. If this is set to true, the CMTS may learn up to docsSubMgtMaxCpeIp
addresses (less any DOCSIS-provisioned entries) related to this CM. Those IP addresses are added (by internal process) to the docsSubMgtCpeIpTable. The nature of the learning mechanism is not specified here.
If not set through DOCSIS provisioning, this object defaults to docsSubMgtCpeLearnableDefault. Note that this object is only meaningful if docsSubMgtCpeControlActive is true.
What is docsSubMgtCpeControlLearnable?
This read-write boolean controls whether the CMTS is allowed to learn and pass traffic for CPE IP addresses associated with a cable modem, up to the configured maximum, adding discovered addresses to the docsSubMgtCpeIpTable. Operators toggle this to decide between strict, provisioning-only CPE lists versus dynamic learning of devices as they appear on the subscriber's LAN. For example, disabling learnability on a modem would mean any new device plugged in behind it won't automatically gain forwarding access unless its IP was pre-provisioned.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.125.1.1.1.3 snmpwalk -v2c -c public <target> DOCS-IETF-SUBMGT-MIB::docsSubMgtCpeControlLearnable
Get a specific instance (index 1):

Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.2.1.125.1.1.1.3.1 s <value>
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> docsSubMgtCpeControlLearnable.1
