STP Features

Extreme Networks switching devices provide seamless Spanning Tree functionality by:

• Creating a single Spanning Tree from any arrangement of switching or bridging elements.
• Compensating automatically for the failure, removal, or addition of any switching device in an active data path.
• Achieving port changes in short time intervals, which establishes a stable active topology quickly with minimal network disturbance.
• Using a minimum amount of communications bandwidth to accomplish the operation of the Spanning Tree Protocol.
• Reconfiguring the active topology in a manner that is transparent to stations transmitting and receiving data packets.
• Managing the topology in a consistent and reproducible manner through the use of Spanning Tree Protocol parameters.
• Increasing security and reliability with SpanGuard, as described below and in What Is SpanGuard?.
• Further protecting your network from loop formation with Loop Protect, as described below and in What Is Loop Protect?.
• Supporting more port density and faster port speeds as described in Updated 802.1t.
• Supporting the Restricted Topology Change Notice (TCN) feature as described in Restricted Topology Change Notification (TCN).
• Supporting the Restricted Role feature as described in Restricted Role
