Enabling Rapid Spanning Tree Protocol Globally
Enable RSTP globally on all participating bridges; it is not enabled by default.
When you enable RSTP, all physical and port-channel interfaces that are enabled and in Layer 2 mode are automatically part of the RST
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.
To enable RSTP globally for all Layer 2 interfaces, use the following commands.
1 Enter PROTOCOL SPANNING TREE RSTP mode.
CONFIGURATION mode
protocol spanning-tree rstp
2 Enable RSTP.
PROTOCOL SPANNING TREE RSTP mode
no disable
Examples of the RSTP show Commands
To disable RSTP globally for all Layer 2 interfaces, enter the disable command from PROTOCOL SPANNING TREE RSTP mode.
To verify that RSTP is enabled, use the show config command from PROTOCOL SPANNING TREE RSTP mode. The bold line indicates
that RSTP is enabled.
