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 bridge1 and port status provide a rich set of tools for performance
monitoring and debugging.
SNMP manageable including newRoot and topologyChange traps.
1 Historically, a device implementing STP on its ports has been referred to as a bridge. RuggedCom uses the term
bridge and switch synonymously.
