@Clive_A Thank you for your reply.

I connect RE550 one by one, on the sixth RE550 the network freeze, so I check the LAN cables(no problem found)

next, I connected the other batch of 6 RE550, so the same thing happened.

after restarting the switch I check the systems logs.  I found a warning threshold high of 87% same time the network froze.

Next, I replaced the tplink  manage switch with another brand but sadly same result. 

what I did was I used my old Unmanaged switch and connected all RE550... then finally NO NETWORK FREEZE. for 24 hours seems no problem with the Re550.

So I'm confused, about using Manage switch on tether devices like RE550.

Is there other way to use my manage switch on RE550?

It freezes for a reason. What does the log say?

It seems to be a loop to me. I am still pointing you in this way.

If you say an unmanaged switch can make it work, I am suspicious about this statement. I still think you should take a full check in your system.
