What is cadIf3CmtsCmRegStatusIPv6Addr?

This OID stores the IPv6 address assigned to a cable modem when it registers with the cable modem termination system (the operator's equipment). If the modem hasn't been assigned an IPv6 address, it shows all zeros. A cable network operator would look this up when provisioning IPv6 connectivity or troubleshooting why a modem can't connect to IPv6 network services.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.4998.1.1.20.2.2.1.30
snmpwalk -v2c -c public <target> CADANT-CMTS-MAC-MIB::cadIf3CmtsCmRegStatusIPv6Addr

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.4998.1.1.20.2.2.1.30.1
snmpget -v2c -c public <target> CADANT-CMTS-MAC-MIB::cadIf3CmtsCmRegStatusIPv6Addr.1
