Module: DOCS-SUBMGT3-MIB
OID (symbolic): DOCS-SUBMGT3-MIB::docsSubmgt3CpeCtrlMaxCpeIpv4
OID (numeric): 1.3.6.1.4.1.4491.2.1.10.1.2.1.1
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-write
Description: This attribute represents the number of simultaneous IP v4 addresses permitted for CPE connected to the CM. When the MaxCpeIpv4 attribute is set to zero (0), all Ipv4 CPE traffic from the CM is dropped. The CMTS configures this attribute with whichever of the 'Subscriber Management CPE IPv4 List' or 'Subscriber Management Control-Max_CpeIPv4' signaled encodings is greater, or in the absence of all of those provisioning parameters, with the CpeMaxIp v4Def from the Base object. This limit applies to learned and DOCSIS-provisioned entries but not to entries added through some administrative process at the CMTS. Note that this attribute is only meaningful when the Active attribute of the CM is set to 'true'.
What is docsSubmgt3CpeCtrlMaxCpeIpv4?
This per-CM value (0-1023) reports the actual number of simultaneous IPv4 addresses the CMTS currently permits for CPEs behind a specific cable modem, taken from the CM's signaled DOCSIS TLVs or falling back to the Base object's default. Setting this to 0 causes the CMTS to drop all IPv4 CPE traffic from that modem; it's only meaningful when the modem's Active flag is true.
