When should I enable STP?

[rdrisaldi]

Hello,

I have my network with serie 300 switches. One is working in layer 3 mode and all others switches are in layer 2 mode.

I dont have redundant path between switches. Should I enable STP? or is not necessary?

Thanks a lot.

If you don't have redundant paths, STP is not necessary but can be useful to prevent problem do to accidental loop.

Hi Ruy,

It is rare for STP to cause problems. There are a few rare cases that it will cause a problem but overall having STP enabled should not impact your network.

I would recommend double checking everything on your network before disabling STP. It only takes one missed cable and your whole network will freeze in a broadcast storm.
