A table containing attributes necessary to find and analyze the operation of all links and nodes within the PNNI hierarchy, as seen from the perspective of a local node. An instance of a pnniMap Object describes a link in terms of a node at one end of the link. Normally there will be two instances of the pnniMap object in the MIB for each horizontal link. The two instances provide information for Network management to map port identifiers from the nodes at both ends to the link between them. A concatenation of the Local Node Index, Originating Node Identifier and Originating Port Identifier are used to form the instance ID for this object.

This entire object is read-only, reflecting the fact that the map is discovered dynamically during operation of the PNNI protocol rather than configured.
