Module: DOCS-SUBMGT3-MIB
OID (symbolic): DOCS-SUBMGT3-MIB::docsSubmgt3CpeCtrlMaxCpeIpv6Addresses
OID (numeric): 1.3.6.1.4.1.4491.2.1.10.1.2.1.2
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-write
Description: This attribute represents the maximum number of simultaneous IPv6 prefixes and addresses that are permitted for CPEs connected to the CM. When the MaxCpeIpv6Prefix is set to zero (0), all IPv6 CPE traffic from the CM is dropped. The CMTS configures this attribute with whichever of the ('Subscriber Management CPE IPv6 List (TLV 67)' plus 'Subscriber Management CPE IPv6 Prefix List (TLV 61)') or ('Subscriber Management Control Max CPE IPv6 Addresses (TLV 63)') signaled encodings is greater, or in the absence of all of those provisioning parameters, with the MaxIpv6AddressDef 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'.
All IPv6 addresses, including Link-Local and any address with a scope greater than 1 are counted against the docsSubmgt3CpeCtrlMaxCpeIpv6Addresses.
What is docsSubmgt3CpeCtrlMaxCpeIpv6Addresses?
This deprecated per-CM value (0-1023) reported the maximum number of simultaneous IPv6 addresses and prefixes, including Link-Local, permitted for CPEs behind a specific modem, sourced from DOCSIS TLVs or the Base default. Setting it to 0 dropped all IPv6 CPE traffic for that modem; it has been superseded by the separate address/prefix limit objects.
