Path Costs - AMX NXA-ENET8-2POE Operation/Reference Manual

STP/RSTP/CIST Port Configuration parameters (Cont.)
• Point-to-Point
You may use a different priority or path cost for ports of the same media type to indicate the preferred path,
edge port to indicate if the attached device can support fast forwarding, or link type to indicate a point-to-point
connection or shared-media connection. (References to ports in this section means interfaces, which includes
both ports and trunks.)

The link type attached to an interface can be set to automatically detect the link
type, or manually configured as point-to-point or shared medium. Transition to the
forwarding state is faster for point-to-point links than for shared media. These
options are described below:
Auto - The switch automatically determines if the interface is attached to a point-
to-point link or to shared medium. (This is the default setting.) When automatic
detection is selected, the switch derives the link type from the duplex mode. A
full-duplex interface is considered a point-to-point link, while a half-duplex
interface is assumed to be on a shared link.
Forced True - A point-to-point connection to exactly one other bridge.
Forced False - A shared connection to two or more bridges.
