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
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.
DellEMC(conf-rstp)#show config

Figure 113. Rapid Spanning Tree Enabled Globally
To view the interfaces participating in RSTP, use the show spanning-tree rstp command from EXEC privilege mode. If a
physical interface is part of a port channel, only the port channel is listed in the command output.
