RuggedCom RS400 manual Spanning Tree

Spanning Tree

This protocol is automatically turned off in situations where multiple STP bridges communicate over a shared (non point-to-point) LAN. The bridge will automatically take point-to-point to be true when the link is found to be operating full duplex. The point-to-point parameter allows this behavior or overrides it, forcing point-to-point to be true or false. Force the parameter true when the port operates a point-to-point link but cannot run the link full duplex. Force the parameter false when the port operates the link full duplex, but is still not point to point (e.g. a full duplex link to an unmanaged bridge that concentrates two other STP bridges).
