OS10(config)# spanning-tree rapid-pvst force-version stp Supported Releases 10.2.0E or later Rapid Spanning-Tree Protocol Rapid Spanning-Tree Protocol (RSTP) is similar to STP, but provides faster convergence and interoperability with devices configured with STP and MSTP. RSTP is disabled by default. All enabled interfaces in L2 mode automatically add to the RSTP topology. Configuring RSTP is a two-step process: 1. Ensure that the interfaces are in L2 mode. 2. Globally enable RSTP. Enable STP globally and at interface RSTP enables STP on all physical and port-channel interfaces which are in L2 mode to automatically include the interfaces as part of the RSTP topology. Only one path from a bridge to any other bridge is enabled. Bridges block a redundant path by disabling one of the link ports. Enable globally ● Configure Spanning-Tree mode to RSTP in CONFIGURATION mode. spanning-tree mode rstp ● Disable RSTP globally for all L2 interfaces in CONFIGURATION mode. spanning-tree disable 526 Layer 2
