[Dave Sparks <Dave.Sparks () Sophos com>]

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!
