RSTP Does Not Support Which Port State?

RSTP Does Not Support Which Port State? Choose the best option

• Discarding
• Learning
• Forwarding
• Listening

Explanation

RSTP (Rapid Spanning Tree Protocol) is a network protocol that is used to build a logical loop-free topology for Ethernet networks. It supports the following port states:

• Discarding: This state is used when the port is not actively participating in the spanning tree and is not forwarding or receiving any data.
• Learning: This state is used when the port is learning the MAC addresses of devices on the network but is not forwarding or receiving any data.
• Forwarding: This state is used when the port is actively participating in the spanning tree and is forwarding data.
• Listening: This state is used when the port is transitioning between the Discarding and Forwarding states and is not forwarding or receiving any data.

RSTP does not support the Listening state. In RSTP, the Listening state is replaced by the Discarding state, which is used to transition between the Forwarding and Discarding states.

Therefore, the correct answer is: Listening
