ipv6IfLowerLayer

Module: IPV6-MIB

OID (symbolic): IPV6-MIB::ipv6IfLowerLayer

OID (numeric): 1.3.6.1.2.1.55.1.5.1.3

Node type: OBJECT-TYPE

Type: VariablePointer

Access: read-only

Description: This object identifies the protocol layer over which this network interface operates. If this network interface operates over the data-link layer, then the value of this object refers to an instance of ifIndex [RFC1573]. If this network interface operates over an IPv4 interface, the value of this object refers to an instance of ipAdEntAddr [RFC1213].

If this network interface operates over another IPv6 interface, the value of this object refers to an instance of ipv6IfIndex. If this network interface is not currently operating over an active protocol layer, then the value of this object should be set to the OBJECT ID { 0 0 }.

This object is obsolete. The IF-STACK-TABLE may be used to express relationships between interfaces.

What is ipv6IfLowerLayer?

Pointed to the layer this IPv6 interface ran over — an ifIndex instance for a data-link interface, an ipAdEntAddr instance for an IPv4-tunneled interface, or {0 0} if not active. It's obsolete; the ifStackTable now expresses these interface-layering relationships.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.55.1.5.1.3
snmpwalk -v2c -c public <target> IPV6-MIB::ipv6IfLowerLayer

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.55.1.5.1.3.1
snmpget -v2c -c public <target> IPV6-MIB::ipv6IfLowerLayer.1
