How to configure RSTP on TP-Link switches using the old GUI

STP (Spanning Tree Protocol), subject to IEEE 802.1D standard, is aimed at disbranching a ring network in the Data Link layer of local area network. Devices running STP can discover loops in the network and block ports by exchanging information. Then a ring network can be disbranched to form a tree-topological no ring network to prevent broadcast storm. RSTP refers to deliver a very fast way to convergence.

Now let’s learn how to configure RSTP on TP-Link Switches by the following example:

Network Topology:

Three switches are under the same VLAN

Attention:

1. Please configure the RSTP of switches first and then connect them together to avoid the broadcast storm.
2. In this test we will let three switches elect root switch automatically. If you want to set a specific switch as root switch, please set CIST priority number of the switch smallest among three.

Here we take TL-SG3424P、TL-SL5428E and TL-SL3428 as an example.

The connection of three switches shows as the topology.

Configuration steps:

1. Choose the menu Spanning Tree→STP Config→STP Config to load the following page, Enable STP and select version RSTP on Three switches.

2. Choose the menu Spanning Tree →Port Config and Enable the

Up-link port status on TL-SG3424P、TL-SL3428 and TL-SL5428E.

The Up-link port is the port which connected to other switches.

3. Then we can see three switches elected the root switch TL-SL3428 via RSTP through menu Spanning Tree→STP Config→STP Summary.

4. We can see the STP version and port role on three switches.

TL-SG3424P

TL-SL3428

TL-SL5428E

5. Now we can make clear which port was blocked via RSTP. From the port role we can see port 1 of TL-5428E was blocked.

So the finally topology is the following:

Finally, the network will work normally.
