System Description of SCALANCE X-400

●C-PLUG

When replacing a device, the C-PLUG can be removed and inserted in the new device so that the configuration can be retained.

●VLAN

SCALANCE X-400 has port-based support of virtual networks (VLAN). A physi- cal network can be divided into several virtual networks. This results in less net- work load compared with other defined VLANs.

●Spanning Tree / Rapid Spanning Tree

SCALANCE X-400 can process both the Spanning Tree Protocol (STP) and the Rapid Spanning Tree Protocol (RSTP). This prevents circulating packets and, in the event of a link going down, quickly provides an alternative path. With the spanning tree protocol, the reconfiguration time is between 20 and 30 seconds, with rapid spanning tree, it is approximately one second. Spanning tree / rapid spanning tree is disabled as default.
