When using Spanning Tree Protocol What is the first step?

When using Spanning Tree Protocol What is the first step?

When using Spanning Tree Protocol, what is the first step in selecting paths through a network? STP must first select the root bridge, or master bridge. 24.

Why is Spanning Tree Protocol STP important in switching?

The Spanning Tree Protocol (STP) is responsible for identifying links in the network and shutting down the redundant ones, preventing possible network loops. In order to do so, all switches in the network exchange BPDU messages between them to agree upon the root bridge.

What is STP What’s a root bridge How’s it elected?

A Root Bridge is a reference point for all switches in a spanning-tree topology. Across all connected switches a process of election occurs and the Bridge with the Lowest Bridge ID is elected as the Root Bridge. When Switch B receives the BPDU from Switch A it compares the Bridge ID of itself with that of Switch A.

When should I use Spanning Tree Protocol?

Spanning Tree Protocol (STP) is a Layer 2 network protocol used to prevent looping within a network topology. STP was created to avoid the problems that arise when computers exchange data on a local area network (LAN) that contains redundant paths.

What is Spanning Tree Protocol Geeksforgeeks?

Spanning tree protocol prevent looping of frames around LAN by placing ports of switch in either forwarding or blocking state. Interfaces (ports of switch) which are in forwarding state act as normally but Interfaces in blocking state doesn’t process any frame received except STP messages and other important overheads.

What is the first of the three steps that the Spanning Tree Protocol algorithm takes when a network is converging for the first time?

The STP network convergence consists in three steps: elect a root bridge, elect root ports and elect designated and non-designated ports. When you enable STP, the first step in its convergence process is to elect a switch to act as a root bridge using the Spanning Tree Algorithm.

What is the purpose of Spanning Tree Protocol in a switched LAN as discussed in this chapter?

The Spanning Tree Protocol (STP) is a network protocol that builds a loop-free logical topology for Ethernet networks. The basic function of STP is to prevent bridge loops and the broadcast radiation that results from them.

READ:   How can I self educate myself?

How does Spanning Tree Protocol prevent loops?

STP prevents loops by blocking one or more of the links. If one of the links in use goes down, then it would fail over to a previously blocked link. How spanning tree chooses which link to use depends entirely on the topology that it can see.

How does spanning tree determine priority?

To verify the bridge priority of a switch, use the show spanning-tree command. In Example 3-4, the priority of the switch has been set to 24,576. Also notice that the switch is designated as the root bridge for the spanning-tree instance.

What happens when STP is disabled?

Disabling Spanning Tree Protocol (STP) can cause Broadcast Storms and Layer 2 Switching Loops, which can make your network down within a short span of time.

What is spanning tree protocol and how it work?

The Spanning Tree Protocol (STP): The Spanning Tree Protocol ( STP) is a network protocol that ensures a loop-free topology for any bridged Ethernet local area network.

  • What is the purpose of the Spanning Tree Protocol?

    The function of Spanning Tree Protocol (STP) is to prevent Layer 2 switching loop and broadcast storms in a Local Area Network (LAN). The Spanning Tree Protocol (STP) allows redundant links in a network to prevent complete network failure if an active link fails, without the danger of Layer 2 Switching loops.

    What is a characteristic of a spanning tree protocol?

    This is a Cisco enhancement of STP that provides a separate STP instance for each VLAN.

  • Each instance supports PortFast,BPDU guard,BPDU filter,root guard,and loop guard.
  • This design allows the spanning tree to be optimized for the traffic of each VLAN.
  • How to configure spanning tree?

    Log in to the web-based utility and choose Spanning Tree > STP Status&Global Settings.

  • Check the Spanning Tree State check box to enable spanning tree.
  • (Optional) Check the STP Loopback Guard check box to enable the feature.
  • Choose the STP Operation Mode.
  • (Optional) Choose the BPDU Handling mode.
  • Choose the Path Cost Default Values.
