Which command displays the status of the default modes of the PortFast and BPDU Guard features?

The command that displays the status of the default modes of the PortFast and BPDU Guard features is "show spanning-tree summary." This command provides a consolidated view of the spanning tree configuration across the entire switch, highlighting various settings and statuses of features such as PortFast and BPDU Guard.

When you use this command, it reveals important information, including whether PortFast is enabled on ports and the configuration for BPDU Guard. This is valuable for network administrators to ensure that these features are correctly set up to enhance network stability and prevent loops. Understanding the status helps in troubleshooting and optimizing the network.

The other commands listed do not provide the same comprehensive overview of the PortFast and BPDU Guard settings. For example, while "show spanning-tree status" might display information about the spanning tree operations, it does not include the specific details related to PortFast and BPDU Guard. Similarly, "show interface status" focuses on the physical interface status, and "show portfast status" typically pertains to individual PortFast configurations rather than the broader spanning tree status.
