Hi all,
   I want to isolate several switches from the production network using 
flowvisor.
   Here's an example of flowspace configure:      dpid1  100  any  Slice:test=4
      dpid2  100  any  Slice:test=4
      ...
      any  10  any  Slice:production=4

  But these switches can still ping others while two slices' nox running 
'switch' application. (Though it's not the case I want, it seems to be 
correct.) Can flowvisor isolate the network in a way like vlan (but not using 
vlan)? I mean, the switches can't connect to others as if they are in different 
vlans.
   I guess it need the action of deny, but I don't know how to configure it in 
the current version (I remember the old version has this feature).
   Does the current version support 'deny' action, perhaps like 'Slice:xxxx=0'? 
If not, is this goal achievable, how?
   
 Best Regards,
 Xu Yang
