CFM decoder

Question

Is cfm packet decoder supported in Wireshark 1.6.1.If affirmative, could you please provide steps on how to activate it?

Thanks very kindly

Answer 1

Wireshark has a dissector for CFM;

From the source code:

/* This code is based on the IEEE P802.1ag/D8.1 document, and on the ITU-T Y.1731
 * recommendation (05/2006,) which is not formally released at the time of this
 * dissector development.  Any updates to these documents may require additional
 * modifications to this code.
 */

No special action is required to activate the dissector.

I note that support for the following was added quite recently (and thus probably is not in Wireshark 1.6.1):

This patch adds support for the two-way Sythetic Loss Measurement
opcodes (SLM & SLR) defined in the latest ITU-T Y.1731.
