Our network has a single 2900 switch with two servers and 10 hubs attached, and there are no plans to change the configuration any time soon. In this enviroment, all STP appears to buy me is a BDPU packet sent out every port, every 2 seconds.... I am planning on disabling STP, but I wanted to know if this sounds appropriate to you?

Do you have any VLANs configured? I imagine you probably don't. In which case, I would certainly disable STP. No reason to have that unecessary overhead. | |

| VLANs aren't what you have to worry about...
What will be your MAJOR concern is having somebody plug an existing working, hub into another port on the switch by "accident". You have an instant loop created and down will come your network without STP.
Just to clarify the hub comment. Assume it's a stand alone hub or daisy chained to another hub, but in either case already connected to the switch. Somebody comes in and runs a patch cable from the hub to another drop on the wall which is connected to another port on the same switch....poof!
Don't laugh, it will probably happen!

| I agree with Yankee. The traffic created by stp would be very little for one switch and the risk is very real.

| I agree too, STP's overhead is very little compared to its benefit. If a loop is to occur on your network then obviously your network performance will worsen, until you network goes down, I would leave STP running. | |

| Thanks Yankee!
You are right, there are too many people out there who wouldn't take the time to understand the existing cabling before "making improvements". So, better safe than screwed...

| Think you came to the right conclusion for exactly the right reason
