Hi @Maximums 

Thanks for posting in our business forum.

  @Clive_A  thank you for Replying.

 

We are an isp and we have arround 30+ switches in RSTP. 

 

we have Huawei switch as core Switch..  when we connect Tplink with Huawei switch say huawei port 1 to tplink port 1. Port gets up but it shows port role Designated on tplink port1. the same port should become Root. 

 

when i connect maipu or edgcore switch in between huawei and tplink .. port 1 on tplink becomes port role Root.  

 

kindly give us a solution over this ... 

 

 

 

Change the priority of the RSTP on the TP-Link. Will it be recognized as the Root?

The priority of other vendors might be higher than our default value. That might be the case where you see a different result.

Hello, @Clive_A

We tried this but didnt work
