This counts entries in a port's address table for stations that actually live on segments attached to other ports, learned here only because the switch needs to know how to reach them through this port's neighbor relationships. An admin expects this to be high on uplink/trunk ports connecting to the rest of the network and low on simple access ports, so a big remote-station count on what should be an edge port could indicate a misconfigured trunk or unexpected bridging loop. Comparing this figure to cat2600TsPortLocalStations for the same port quickly tells you whether that port is acting as an access link or a backbone link.
