I am brand new to Wireshark. I want to capture some BGP opens and updates, however, it is capturing absolutely everything that comes over the switch; including BPDU's every 2 secs. None of the built-in filters seem designed to filter out STP traffic. And I'm confused about creating a new filter; it says I must give a "protocol value" even after selecting stp from the menu.
Any advice would be much appreciated.
