Configuring STP on a Ruijie Switch

 

hi kids, this is your dad, huahuanjayy wkwkwk, Nuenomaru the handsome is back in action.

Okay, this time your dad is going to write a tutorial Configuring STP on a Ruijie Switch. Ruijie Networks switches support the Spanning Tree Protocol (STP) to help prevent network loops and improve overall network stability. Proper STP configuration ensures efficient traffic flow, minimizes broadcast storms, and provides redundancy in Layer 2 network environments. In this article, we will discuss the basic steps for configuring STP on a Ruijie switch and best practices for maintaining a reliable network infrastructure.

STP introduction:

- A local area network (LAN) generally has redundant links. A method is required: 1.to block redundant links, remove path loops,2.automatically switch redundant links to the forwarding state when necessary to restore network connectivity.

- Spanning tree protocols can achieve this function. Spanning tree protocols include Spanning Tree Protocol (STP), Rapid STP (RSTP), and Multiple STP (MSTP).

- This course focuses on the principles of STP (Spanning Tree Protocol) and the steps for configuring STP through EWEB.

- STP is a protocol used to remove loops on a layer-2 network.

1 Block redundant links to remove possible path loops on a bridge network.

2 Activate the redundant backup link to restore network connectivity when the current active path is faulty.

- Bridge ID: A bridge ID uniquely identifies a bridge in the STP. A bridge ID consists of the following two parts and has eight bytes.

1 Bridge Priority: Higher 16 bits

2 MAC Address: Lower 48 bits

- Path Cost

1 Path Cost is used to balance the advantages and disadvantages of paths between bridges.

2 Each link in STP has a cost value.

STP Configuration in EWEB:

Path: Project > Device > Select the device > Click eWEB > Click Open with Domain

Configuring STP through the EWEB of a switch, using the NBS3300 as an example.

STP configuration path: Advanced>STP

- Generally, it is necessary to manually configure the core switch as the root bridge to ensure the stability of the network topology.

1 Priority: The switch priority, used for root bridge election, can be set through a dropdown option within the range of 0-61440 (in multiples of 4096). A lower numerical value represents a higher priority. Typically, the priority of a switch manually set as the root bridge is configured to 0.

2 Hello Time: The interval for periodically sending Bridge Protocol Data Units (BPDUs).

3 Max Age: The aging time for BPDU messages.

4 Forward Delay: In STP mode, the interval for transitioning the state of a switch port, defaulting to 15 seconds. It is used to avoid creating temporary loops.

5 Recovery: Auto Recovery Time of Errdisabled Port, with a default duration of 30 seconds.

- To optimize data forwarding paths, one can set the STP parameters of interfaces to influence the election of Root Port and Designated Port, thereby enhancing the overall data forwarding efficiency of the network.

- Port Fast: Enabling Port Fast allows the port to skip the listening and learning states, and directly enter the Forwarding state. It is generally recommended to enable this feature on interfaces connected to end devices.

- BPDU Guard: Enabling this feature can prevent attackers from causing network fluctuations by falsifying Bridge Protocol Data Units (BPDUs), thereby increasing network stability. It is recommended to enable it.

- Priority: Interface priority is a data that affects the role of the interface. The smaller the value, the higher the priority. The default value is 128.

In conclusion, configuring STP on a Ruijie Networks switch is an essential step to keep your network stable, efficient, and free from looping chaos. With the right configuration, your switches can work together smoothly without arguing over who should forward the traffic. Because in networking, too many paths without STP is basically just digital traffic jam.

Hahaha alright, that’s a wrap for today’s article—my coffee’s gone, so that’s my cue to stop typing.

Let’s end this with a Bismillah at the start and an Alhamdulillah at the finish. Catch you next time, tech gembelers!.
