Help Please on Disabling Spanning Tree on a 8450

I have a 8540 with a single bridge group (1) that I need to shut spanning tree off on because I have high end users as well as servers on it and users turning their machines off and on are causing multiple convergences. How do I do this?

Would it be an option to enabled spanning-tree portfast on the user/edge ports in question? That should prevent TCN BPDUs from being sent.

for most IOS devices it is just "spanning-tree portfast" on the interfaces . Others will accept the switchport host command .
