Description: This table contains the attributes necessary to describe the operation of logical links attached to the local switching system and the relationship with the neighbor nodes on the other end of the links. Links are attached to a specific node within the switching system. A concatenation of the Node Index of the node within the local switching system and the port ID are used as the instance ID to uniquely identify the link. Links may represent horizontal links between lowest level neighboring peers, outside links, uplinks, or horizontal links to/from LGNs.

The entire qbAtmPnniLink object is read-only, reflecting the fact that this information is discovered dynamically by the PNNI protocol rather than configured.
