Module: DOCS-SUBMGT3-MIB

OID (symbolic): DOCS-SUBMGT3-MIB::docsSubmgt3BaseCpeMaxIpv6PrefixesDef

OID (numeric): 1.3.6.1.4.1.4491.2.1.10.1.1.15

Node type: OBJECT-TYPE

Type: Unsigned32

Access: read-write

Description: This attribute represents the maximum number of IPv6 IA_PDs (delegated prefixes) allowed for the CM's CPEs if not signaled during the registration process. IPv6 IA_PDs are counted against the CpeMaxIpv6PrefixesDef. This contrasts with the CpeMaxIPv4AddressesDef addresses, rather than IPv4 subnets, allowed by default per CM. Because this attribute only counts IA_PDs against the default, IA_NA addresses and Link-Local addresses are not counted against this default limit.

What is docsSubmgt3BaseCpeMaxIpv6PrefixesDef?

This read-write value sets the CMTS-wide default limit (0-1023, default 3) on how many IPv6 delegated prefixes (IA_PDs) a CM's CPEs can hold when the CM's registration didn't signal its own limit. Unlike the IPv4 default, this counts only delegated prefixes, not individual IA_NA addresses or Link-Local addresses.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.4491.2.1.10.1.1.15
snmpwalk -v2c -c public <target> DOCS-SUBMGT3-MIB::docsSubmgt3BaseCpeMaxIpv6PrefixesDef

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.4491.2.1.10.1.1.15.1
snmpget -v2c -c public <target> DOCS-SUBMGT3-MIB::docsSubmgt3BaseCpeMaxIpv6PrefixesDef.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.4491.2.1.10.1.1.15.1 i <value>
