Configure Rapid Spanning Tree Protocol (RSTP)
The Rapid Spanning Tree Protocol (RSTP) is a Layer 2 protocol which ensures a loop free topology on a
switched or bridged LAN while allowing redundant physical links between switches. When enabled, the
TransPort device uses RSTP but this is backwards compatible with STP.
If the router is in Port Isolate mode, RSTP is not enabled. If an Ethernet interface is configured with a
hub group, RSTP is disabled on that interface.
