Note: As of Wireshark 2.6, this dissector is pre-bundled and does not need separate downloading and installation. Simply enable it via Analyze => Enabled Protocols => F5 Ethernet trailer => f5ethtrailer[1].

 

Installation

1. Download and install Wireshark:

  • 01.09.00 (released 12/16/2014) - Version 1.9 of the plugin includes binaries for wireshark versions 1.8, 1.10, and 1.12 on linux and windows for the wireshark 32bit/64bit application.
  • 01.10.00 (released 04/09/2015) - Version 1.10 of the plugin adds support for v12 and fixes a minor bug. Binaries for WS 1.8, 1.10, 1.12 for Win32, Win64, Linux32, and Linux64 included.
  • 01.11.00 (released 06/04/2016) - Version 1.11 of the plugin adds support for Wireshark 2.0. Binaries for WS 1.10.2, 1.12.1, and 2.0.1 for Win32, Win64, Linux32, Linux64, and OS X included.
  • 01.11.01 (released 03/20/2017) - Version 1.11.a (1.11.01 in the version list below) of the plugin adds support for Wireshark 2.2. Tested on versions:
    • Win32/Win64 - 2.2.4/2.2.5
    • Linux64 - 2.2.0/2.2.4/2.2.5
    • Linux32 - 2.2.0/2.2.4
    • OSX - 2.2.0/2.2.5
  • 01.11.02 (released 09/25/2017) - Version 1.11.b (1.11.02 in the version list below) of the plugin adds support for Wireshark 2.4.

2. Extract f5ethtrailer.dll from the appropriate folder for your system.  For my Wireshark 1.10 64-bit installation, that folder is Win64_WS1-10-2.
3. Copy the file to the Wireshark plugins folder (on my system, it is C:\Windows\Program Files\Wireshark\plugins\1.10.11)

3. Launch Wireshark. Go to Help->About Wireshark. Click the Plugins tab. The f5ethtrailer.dll should be listed.

Usage

In order to utilize the Wireshark plugin, you need to flag the tcpdump command appropriately with -s0 and setting the level of noise by flagging the interface with a colon followed by a single, double, or triple n for, respectively, low, medium, and high details. For example:

tcpdump -s0 -ni vlan:nnn -w/var/tmp/filename.pcap

 

The basic information for each noise level is below. For greater details, please reference Solution 3637.

 

  • Low Details (:n) - The low details include ingress or egress flow direction, the slot and TMM handling the packet, and the vip, if applicable.
  • Medium Details (:nn) - The medium details include the low details plus flow and peer IDs, and the F5 reset cause. The remaining fields in the medium details are likely only helpful to F5 support.
  • High Details (:nnn) - The high details include the low and medium details plus all the related peer data, protocol, vlan associated with the flow, and local and remote addresses and ports. You'll want this setting for the F5 conversation menu items.

So what does the package capture look like once loaded into Wireshark? Well, first off, you'll notice an INFO frame that provides not only the hostname and platform information of the BIG-IP the packet capture was taken from, but also the tcpdump parameters that were set.

 

0151T000003d6OgQAI.jpg

 

Next, take a look at a packet that is actually hitting a virtual server:

 

0151T000003d6OhQAI.jpg

 

Here, you can see that the packet is being handled by TMM 1 and is hitting the /Common/tesvip virtual server. Also useful is the flow ID, which allows you to bind the front-end client connection with the associated back-end connections. You can either right-click the flow ID and select Apply as Filter and then Selected:

 

0151T000003d6OiQAI.jpg

 

Or, you can just set the filter manually in the filter field (f5ethtrailer.flowid == 0x0000570075cfd200):

 

0151T000003d6OjQAI.jpg

 

John T, one of our excellent engineers, suggested that you should use the f5ethtrailer.anyflowid filter if you're going to type it out as that will get you packets where that flow id is the flowid OR the peerid, resulting in getting both the client and server side of the connection. John is also the source of much of the rest of this article, so hat tip his way!

Starting in version 1.9 of the plugin, you can also select from a few F5 conversation filters (as appropriate) directly in the menu:

 

0151T000003d6OkQAI.jpg

 

This is a shortcut for:

 

(ip.addr eq 192.168.101.1 and ip.addr eq 192.168.101.51 and tcp.port eq 61843 and tcp.port eq 80) or \
(f5ethtrailer.peeraddr eq 192.168.101.1 and f5ethtrailer.peeraddr eq 192.168.101.51 and f5ethtrailer.peerport eq 61843 \
and f5ethtrailer.peerport eq 80 and (f5ethtrailer.peeripproto eq 6 or (f5ethtrailer.peeripproto eq 0 and tcp)))

That's quite a shortcut! I can't imagine remembering all those switches, let alone typing it all without fat-fingering something.

You can filter on many other fields in the plugin, but hopefully this is a good launch point for you to get started with analyzing your BIG-IP traffic flows. Happy analysis!


[1] Missing Trailers / Low Noise: If you are missing the Low details of the trailer for some packets (typically short packets), try modifying the settings for the Ethernet dissector. Go to "Edit/Preferences...", expand "Protocols" on the left and select "Ethernet". Disable "Assume short frames which include a trailer contain padding".

Starting in BIG-IP v14.1.0, if that preference is enabled, trailers, not just low noise, will be missing on short packets.

Hi Zup, the plugin should work with 1.12, but I was having local system issues in my attempt. YMMV.

It's sad but doesn't work with Wireshark 1.12.2. That would be great if someone could build plugin for 1.12.x. It's not a usual task on windows if you're not developer.

Great Job!! My custome can see now the traffic around the BIG-IP and help in a lot of troubleshootings.
I upgraded the wireshark from 1.10 to 2.0 but side effect is, this plugin did not load at all. so that I had to install wireshark version 1.0 , which in turn unintalled the 2.0 and voila , now it is working perfectly .... Neeraj Jagetia

Plugin is working with Wireshark-win64-2.0.7, Wireshark-win64-2.0.6, Wireshark-win64-2.0.5 When you performing update 2.0.x 64bit, then do not forget copy plugin file (wireshark-plugin.f5ethtrailer.bin.1.11.zip\Win64-2.0.1\f5ethtrailer.dll) to new plugin folder, currently "c:\Program Files\Wireshark\plugins\2.0.7\"

WireShark 2.2.1 is released. And Since 2.05 the updated Windows plugin doesn't work on 32-bit. Apparently 64bit works on 2.05, 06, 07....But nothing works for 2.2.0 or 2.2.1

 

Is there a doc that explains how to compile, step by step, so we can do this and not have to wait for F5 guys to do it?

Wow. I looked and I admit defeat. How does that create the f5plugin.dll file? I think I got lost at Chocolatey. lol. Kudos to whoever processes that for the rest of us. I wonder if a script could be run to make it easier.

As of Wireshark 2.6 (rel. 4/24/2018) the f5ethtrailer is included as a built-in dissector. Wireshark 2.6.0 incorporated the 1.11b version of the dissector.

 

https://www.wireshark.org/news/20180424.html

 

It is disabled by default. To enable it, from the menu select "Anyalyze" : "Enabled Protocols...". Then search for f5ethtrailer and enable the dissector.
