whether its PVRST+ or MST used, you should always mark your 'edge'  
port correctly as being 'edge' such that they are operating as  
"portfast" with "bpduguard".

it sounds like you have edge ports configured as "network" ports - so  
the system HAS to wait for the "forwarding delay".
since you're saying that is 30 seconds not 15 seconds, that implies  
the system is falling back to legacy (802.1D-2004) behavior.
