ibIpoibLinkLayerAddr
Module: IB-IF-MIB
OID (symbolic): IB-IF-MIB::ibIpoibLinkLayerAddr
OID (numeric): 1.3.6.1.3.117.2.1.3.1.3
Node type: OBJECT-TYPE
Type: IbIpoibClientIdentifier
Access: read-only
Description: A Client Identifier for this interface (port). An implementation may associate multiple IPOIB interfaces on the same port. It is up to the implementation to ensure a unique Client Identifier when multiple IPOIB interfaces are defined over the same port and same GID. A unique, invariant interface-id value must be included in addition to the GID within the Client Identifier definition to achieve this. Note: a port may also be associated with multiple GIDs. Therefore, multiple IPOIB interfaces may exist on the same port while using a different GID from among the GIDs associated with the port. In either case, the IbIpoibLinkLayerAddr MUST be unique.
What is ibIpoibLinkLayerAddr?
This reports the IPoIB Client Identifier associated with this interface (port), which uniquely distinguishes the interface when multiple IPoIB interfaces share the same physical port and GID. An admin or management tool uses this identifier to correctly correlate IP-over-InfiniBand interfaces to their underlying physical port when a single port hosts more than one IPoIB interface. For example, on a port carrying two separate IPoIB interfaces over the same GID, each interface would report a distinct ibIpoibLinkLayerAddr value to keep them uniquely identifiable.
Examples
