The show clns neighbors command provides a summary of known neighbors, the connecting interface, and the state of the adjacency. The show clns neighbors detail command provides more information about each neighbor, such as the area that it belongs to and how long it has been known (uptime). Explanation of the fields in this output is as follows:
• System ID? System identifier of the neighbor.
• Interface? Physical interface where the neighbor is connected.
• SNPA? Subnetwork point of attachment. This is the data link type or address (HDLC or PPP for serial, and MAC address for LANs).
• State? State of the adjacency? up, down, or init.
