RSTP Features 

RuggedSwitch™ RSTP provides you with the following features: 

•  Industry standard support of Rapid Spanning Tree (802.1w), which features 

a compatibility mode with legacy STP (802.1d). 

•  Superior performance.  RuggedCom RSTP will recognize a link failure and 

put an alternate port into forwarding within milliseconds. 

•  Special support for ring architectures.  RuggedCom RSTP features 

enhancements, which allow rapid recovery in rings. 

•  RSTP may be enabled on a per-port basis. 
•  Ports may be configured as edge ports, which allow rapid transitioning to 

the forwarding state for non-STP hosts. 

•  Path costs may be hard configured or determined by port speed 

negotiation, in either the STP or RSTP style.  

•  Full bridge

 Historically, a device implementing STP on its ports has been referred to as a bridge.  RuggedCom uses the term 

bridge and switch synonymously.
