Usage Information Example None OS10(config)# spanning-tree vlan 1 root primary Supported Releases 10.2.0E or later 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 are automatically added 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 globally 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 any bridge to any other bridge is enabled. Bridges block a redundant path by disabling one of the link ports. • 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 • Remove an interface from the RSTP topology in INTERFACE mode. spanning-tree disable • Re-enable an interface in INTERFACE mode. no spanning-tree disable • Re-enable RSTP globally for all L2 interfaces in CONFIGURATION mode. no spanning-tree disable Layer 2 241
