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

Question

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:

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

2. In privileged exec mode:

   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.
