Module: DOCS-SUBMGT3-MIB
OID (symbolic): DOCS-SUBMGT3-MIB::docsSubmgt3CpeIpAddrPrefixLen
OID (numeric): 1.3.6.1.4.1.4491.2.1.10.1.3.1.4
Node type: OBJECT-TYPE
Type: InetAddressPrefixLength
Access: read-only
Description: This attribute represents the prefix length associated with the IP prefix (IPv4 or IPv6) that is either set via provisioning or learned via address gleaning of the DHCP exchange or some other means. For IPv4 CPE addresses, this attribute generally reports the value 32 (32 bits) to indicate a unicast IPv4 address. For IPv6 CPE addresses, this attribute represents either a discrete IPv6 IA_NA unicast address (a value of 128 bits, equal to /128 prefix length) or a delegated prefix (IA_PD) and its associated length (such as 56 bits, equal to /56 prefix length).
What is docsSubmgt3CpeIpAddrPrefixLen?
This read-only value reports the prefix length tied to a CPE IP entry: typically /32 for an IPv4 address, /128 for a discrete IPv6 unicast address, or a shorter length like /56 for an IPv6 delegated prefix. It lets an admin tell at a glance whether the CPE entry represents a single host address or a routed prefix.
