The key attributes for ISISAdjacency are the same as those for ISISNeighborEndpoint, except that the attribute names contain 1 or 2 to denote the attribute set for each of the two endpoints involved in the adjacency. The Endpoint1DisplayName and Endpoint2DisplayName attributes identify the IS-IS endpoints for the attribute sets. “Attributes for ISISNeighborEndpoint” on page 45 provides a list of the key attributes for ISISNeighborEndpoint.

Network Protocol Manager for IS-IS uses the two sets of ISISNeighborEndpoint attributes as well as other attributes to diagnose IS-IS network, interface, and adjacency problems, and to detect IS-IS adjacency events.
