Question

You want to run the new 802.1w on your switches. Which of the following would enable this protocol?
Group of answer choices

Switch(config)#spanning-tree mode 802.1w

Switch(config)#spanning-tree mode rapid-pvst

Switch#spanning-tree mode rapid-pvst

Switch#spanning-tree mode 802.1w

Answer 1

To enable the Rapid Spanning Tree Protocol (RSTP), which is defined in IEEE 802.1w, you should use the command that sets the spanning tree mode to rapid-pvst.

The correct commands to enable RSTP would either include:

1. In global configuration mode:
```plaintext
Switch(config)# spanning-tree mode rapid-pvst
```

2. In privileged exec mode:
```plaintext
Switch# spanning-tree mode rapid-pvst
```

So the correct answer from your options would be:

- **Switch(config)#spanning-tree mode rapid-pvst**

or

- **Switch#spanning-tree mode rapid-pvst**

Note: The other options, `Switch(config)#spanning-tree mode 802.1w` and `Switch#spanning-tree mode 802.1w`, are not valid commands to configure the RSTP on standard Cisco switches.
