BPDU packets - fast way to verify all interfaces on a switch

Is there a "range" command to verify if BPDU packets are being sent/recieved on all the interfaces on a switch at the same time?  Or do you have to run the command:



switch#show spanning-tree interface g1/0/52 detail | i BPDU
   BPDU: sent 3, received 351096
   BPDU: sent 3, received 351087
   BPDU: sent 198, received 350950

For each interface individually?

Thanks,

Mike

Hi Mice, 

Please use below commands to get all the ports details which exclude other stuff.
