This command gives information about the neighbouring nodes that can be heard. For each neighbour, the display shows the port number, the callsign, the path quality and the number of nodes accessible through this neighbour. If a route has been 'locked' by the sysop, then a '!' character is shown after an entry. The sysop may have configured the node to display nodes as callsign or as alias:callsign. If so configured, then if a node is shown as a callsign alone it means that is it not currently reachable as its node broadcasts are not being received.
