I think you will want to set the display filter, rather then the capture filter:-

tshark -i vlan701 -R 'not stp'

Hi all,

Any pointers on how to filter out PVST packets?

# tshark -i vlan701 not stp
Capturing on vlan701
 0.000000 Cisco_6a:50:13 -> PVST+        STP RST. Root = 0/1/00:12:f2:94:dc:00  Cost = 7  Port = 0x8013
 2.013488 Cisco_6a:50:13 -> PVST+        STP RST. Root = 0/1/00:12:f2:94:dc:00  Cost = 7  Port = 0x8013
 4.026868 Cisco_6a:50:13 -> PVST+        STP RST. Root = 0/1/00:12:f2:94:dc:00  Cost = 7  Port = 0x8013
 6.039309 Cisco_6a:50:13 -> PVST+        STP RST. Root = 0/1/00:12:f2:94:dc:00  Cost = 7  Port = 0x8013

Thanks!
