Lisa Bock reviews display filters to use when you have already captured packets or are actively capturing.
- [Narrator] Within Wireshark and most packet capture tools,…there are filters to help refine your view.…We have display filters.…We can apply some filter shortcuts.…We can build an expression and create complex filters.…And we can also create a capture filter…to capture only a certain type of traffic.…I'm at this packet capture here,…and as you can see, there's over 3,000 packets…and a lot of different types of traffic.…
The display filter, as you can see here,…it says apply a display filter.…We use a display filter when we've already captured…some packets or are actively capturing packets.…When you use a display filter, it's very simple.…You simply type whatever it is you would like to display.…For example, I would just like TCP traffic,…so I'll type TCP.…Then over here we can either press enter or simply go.…Now within that of course TCP…is the transport layer protocol,…and we see a lot of different types of traffic.…
Within that TCP, I might not want…any of the SSL traffic, so let's build a filter…that removes the SSL traffic.…
