L2 Features > Spanning Tree > STP Global Settings
The Switch implements two versions of the Spanning Tree Protocol: Rapid Spanning Tree Protocol (RSTP)
as defined by IEEE 802.1w, a version compatible with the IEEE 802.1D STP. RSTP can operate with legacy
equipment implementing IEEE 802.1D, however the advantages of using RSTP will be lost.
By default, Rapid Spanning Tree is disabled. If enabled, the Switch will listen for Bridge Protocol Data Unit
(BPDU) packets and their accompanying Hello Packets. The BPDU packets are sent even if a BPDU packet
is not received. Therefore, each connection between bridges is sensitive to the status of the link. Ultimately
this difference results in faster detection of failed links, and therefore faster topology adjustment.
