Internet Security Association and Key Management Protocol (ISAKMP)
The ISAKMP protocol is defined in RFC 2408. It is also commonly called Internet Key Exchange (IKE)
This page is very much a stub! Please help expand it.
XXX - add a brief description of ISAKMP history
XXX - Add example decoded traffic for this protocol here (as plain text or Wireshark screenshot).
The ISAKMP dissector is (fully functional, partially functional, not existing, ... whatever the current state is). Also add info of additional Wireshark features where appropriate, like special statistics of this protocol.
(XXX add links to preference settings affecting how ISAKMP is dissected).
Example capture file
XXX - Add a simple example capture file to the SampleCaptures page and link from here (see below). Keep this file short, it's also a good idea to gzip it to make it even smaller, as Wireshark can open gzipped files automatically.
A complete list of ISAKMP display filter fields can be found in the display filter reference
- Show only the ISAKMP based traffic:
You cannot directly filter ISAKMP protocols while capturing. However, if you know the UDP port used (see above), you can filter on that one.
- Capture only the ISAKMP traffic over the default port (500):
udp port 500

There are some Vendor IDs missing from the filter implementation. It would be great if someone could add them. Identified so far:
