gs510tpp ports losing connection to network

Hi Mate

Thanks for your advice. You are right , I could change the setting in CST port configuration to disable the settings. But would not fix the real problem on the network with the flooding of the BPDU packets. I checked the switches. all flashing like mad. Started foot patrol on the network to all the office and asking questions. A bright staff member found a cable and decided to plug it into the network and created a loopback between two points. 

This slowed down the whole network, internet access on the network was at snails pace and put the 3 Netgear POE switches on the uplink ports to D-Disable.

So everyone could connect to the Ap's but no traffic to anywhere.. I just had all the new cables fitted to 26 rooms for the Rukus AP's back to new patch panels, then put the POE switches in and everything was sweet and fine for 2 days. Well, until yesterday afternoon.

I have it all sorted now and all the switches and AP's back up and running.

I could disable the settings as you suggested, but I think I will leave it. It will tell me if anyone else has created a loopback, not that I want it.

Thank you very much for your advice, It was very helpful and pointed me in the right direction. You Are a star.. and well appreciated.
