Why is that? I only actually selected the first MPLS header. Hmmm, actually that doesn't quite look like what I had does it? Both labels are in the same column. Right click and select 'Apply as a Column.' Go here and download 'mpls-twolevel.cap.' Now, go to packet #17.Įxpand the first MPLS Header and click on the actual MPLS Label. The one where I was showing the 2 MPLS labels to the customer. So let's go back to that trace from above. I find custom columns just about the neatest thing! Perfect for MPLS labels! Perfect for packets with multiple IP addresses like GRE! Go to Edit | Preferences | User Interfaces and then choose Columns. Go down to Properties at the bottom and click ' +Add.' All the pre-defined columns show up. Wireshark has a bunch of pre-defined columns one can choose from. So my current 'favorite items' are really just the things that are new to me. **To be fair I have to point out that I already knew about marking packets, display filters, following a conversation, etc. And then, finally, gain the knowledge I've wanted for over two years now. I knew myself well enough to know that if I signed up for the exam I would make the time in my personal life to study for it. There is a Wireshark certification - The Wireshark Certified Network Analyst. More time and still more time passed.Ībout three months ago I saw my hope for finally really and truly making the time investment. So I went out and bought a book, confident I would make time in my personal life to 'go to the next level' with Wireshark. From the early 90s when I used a W&G sniffer to troubleshoot SNA, through my days with RSRB, DLSw and STUN, through my days of routing and switching, to today. Why? Because while the only thing constant in IT seems to be change, sniffers have been there with me at every turn. Why? Because I really wanted to have that knowledge. And, in 5 minutes, I had no way of keeping up.Īfter the customer left that day I told myself I would spend time 'going to the next level' with Wireshark. I had no idea how much I was underutilizing Wireshark. Looking back now, I wish I had recorded that session. This customer was like a pianist on a keyboard, moving through the Wireshark GUI and trying to pack as much into 5 minutes as he possibly could. At the end of the day we had time for him to give me a 'drinking from the firehouse,' five-minute show and tell of all the things he thought would be useful in my job. Fluent and experienced.
