interface of SW2. It’s called abackup port,and it’s new for rapid spanning tree. You are very unlikely to see this port on a production network, though. Between SW2 and SW3, I’ve added a hub. Normally (without the hub in between) both fa0/16 and fa0/17 would be designated ...
CCNA Routing and Switching 200-120 Network Simulator $149.99 Overview The Spanning Tree Protocol (STP) prevents loops from forming in a switched network, but it does this task inefficiently by comparison with the processing capabilities of modern equipment. This article takes a look at the Rapid...
In pure RSTP, no. If, however, you had Cisco Loop Guard activated on the P4 and the port was not Designated before you deactivated the BPDU Tx and Rx, the loss of received BPDUs on this port will cause Loop Guard to put it into Designated Discarding state. ...
Hi Studying for the CCNA, I'm a bit confused about the definition of the RSTP disabled role I find multiple sources stating that "disabled" means that the port is administratively disabled. However, in the official course guide a few
With the above similarities, you might wonder why the IEEE bothered to create RSTP in the first place. The following section describes the reasons why IEEE had to create RSTP. Differences between RSTP and STP The main reason for creating RSTP was the convergence. Convergence is the time STP ...
（）RSTP (Rapid Spanning Tree Protocol) is used at the data link layer of the OSI model to pr loops. The data link layer is responsible for managing the physical connection between network nodes, and RSTP helps in creating a loop - free topology in Ethernet networks at this layer.
