I have one switch (CE500) in the broadcast domain so I don't need STP running and needlessly using up bandwidth. Is there a way to turn it off?
TIA

I agree with tdrais in regards of disabling STP however, if you still want to accomplish this, go to Configure>VLANs and then click the Advanced button and then you will be able to uncheck the STP opcion for each VLAN.

switch(config)#no spanning-tree vlan x

The commnad in the above post will accomplish the task if you can use cli on these switches.
Disabling spanning tree is a bad idea. Even worse with the newer switches that have mdix on them.
Even though you only have 1 switch you can get spanning tree loops. Spanning tree has saved us so many time when someone is bored sitting in a conference room and plugged 2 jacks together on the table.
The amount of traffic is very very small for stp messages. If you really want to reduce this you can look at a feature called BPDU FILTER but I am unsure it is supported on these small switches.

Thanks for responding. I was aware of that command. The problem I have is that the Catalyst Express 500 has no CLI.
Thanks

Gary,
Thanks for the response. In all my looking around in the GUI I missed that one. Thanks for the warnings, but this is not a production environment it's a classroom environment and I don't want the STP traffic muddling up things when the students use Wireshark.
