|you need to look more into this|
when did the problem happen?
is this a new setup that suddenly stopped working?
are all the switches the same make?
are you sure its broadcast traffic that causing this?
are all the rstp timmers the same? has any one changed the timmers?
is it between two of the switched that you are getting this error?
look at the settings map out what ports would normaly be in blocking mode if everything was working correctly and set up properly?
i presume you know what switch is being effected
im guessing faulty port or that there is wireing problem and the high volume of traffic is just showing the fault up.
