![]() Could be a useful statistics if you working on performance issues in remote IPSec VPN locations. FRAG-PACKET – This rule calls out any fragmented packets by keeping an eye out on the ‘More Fragments’ bit.Might be useful if you are troubleshooting a WLAN performance issue. WLAN-RETYU-PACKET – This filter looks to see if the packet is a retransmission of the RF medium.These coloring rules are tied to specific profiles, so you definitely want to keep in mind what profile you are working under.Below are a few of my coloring rules: It’s important to remember that coloring rules are match from top-to-bottom and they will by specific criteria found in the packet. This allows to quickly scroll through a single capture looking for key characteristics.Ĭoloring Rules – These coloring rules define how Wireshark displays the individual packets, it’s these same coloring rules that make re-transmissions show up in red. There is no need to even close the current capture or restart Wireshark. Those are just a few ways profiles can be leveraged, and remember it is easy enough to flip from one profile to the next. Wired-Transaction-Time – Contains specific columns for relative time & absolute time, etc.Remote-Site-VPN – Calls out specific columns for the DF-Bit, IP & TCP length, and more fragment field.Wired-VoIP – This profile will call out the DSCP field as specific column to easily keep an eye on QoS marking. ![]() ![]() Now, that we know some of the ways profiles affect Wireshark lets consider a few good use cases for profiles, below are a few profiles I have. What columns are displayed in the Wireshark display.Affecting the complete layout of the Wireshark display.Profiles – Profiles give us the ability to control what information Wireshark displays to us, and how the information is displayed. The two most useful features we have are profiles and coloring rules, both of these are very powerful features and using both of these features together allows you to take your analyzing skills to the next level. It does this by giving us the flexibility to control what information Wireshark displays to us and how Wireshark displays that information. Luckily for us, if we know what we are looking for we can configure Wireshark to turn that needle in a haystack into a firework on the middle of Halloween. The more you use Wireshark and the more familiar you get with protocols / packet analysis the quicker you realize what you may need to for. Well, my first draft got lost in the cloud so let’s try this again!
