extEthernetInterfaceStatelessAutoConfigAddressesPrefixLen

Module: CME-MIB

OID (symbolic): CME-MIB::extEthernetInterfaceStatelessAutoConfigAddressesPrefixLen

OID (numeric): 1.3.6.1.4.1.2.3.51.2.4.9.1.4.5.3.3.2.1.3

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: The stateless Auto-Configration address prefix length.

NOTE: If extEthernetInterfaceIPv6StatelessAutoConfigEnabled or extEthernetInterfaceIPv6Enabled is currently disabled, this object will show nothing.

What is extEthernetInterfaceStatelessAutoConfigAddressesPrefixLen?

This read-only integer, from 1 to 128, reports the prefix length of a stateless-autoconfiguration IPv6 address, showing nothing if stateless autoconfiguration or IPv6 itself is disabled. An administrator reads this alongside the address itself to fully understand the subnet the SLAAC-derived address belongs to. For example, an admin combines this prefix length with the reported address to confirm the autoconfigured address falls within the expected management subnet.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2.3.51.2.4.9.1.4.5.3.3.2.1.3
snmpwalk -v2c -c public <target> CME-MIB::extEthernetInterfaceStatelessAutoConfigAddressesPrefixLen

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.2.3.51.2.4.9.1.4.5.3.3.2.1.3.1
snmpget -v2c -c public <target> CME-MIB::extEthernetInterfaceStatelessAutoConfigAddressesPrefixLen.1

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> extEthernetInterfaceStatelessAutoConfigAddressesPrefixLen.1
