Wireshark · Wireshark-users: Re: [Wireshark-users] Dictionary.xml - Bit mapping of AVP value

Hi,

Unfortunatly that is not possible in the .xml files, you would have to code that in packet-diameter_3gpp.c if it's a 3gpp AVP

or in a similar way for standard or other vendors AVP:s.

Regards

Anders

Ref see the code for:

/* AVP Code: 1405 ULR-Flags */

static int

dissect_diameter_3gpp_ulr_flags(tvbuff_t *tvb _U_, packet_info *pinfo _U_, proto_tree *tree _U_) {

Subject: [Wireshark-users] Dictionary.xml - Bit mapping of AVP value

Hi,

How can I map each bit of the value of an AVP to a boolean field?

I have an Unsigned32 AVP on diameter trace which I can get wireshark to dissect, but instead of presenting me the value of the AVP I would like to have a list of features mapped to each bit of the value. Similar to what you get with the TCP flags.

Example:

If the value is 18 hex, I would like to have:

0---   ----   = Feature 0 = Off
-0--   ----   = Feature 1 = Off
--0-   ----   = Feature 2 = Off
---1   ----   = Feature 3 = On
----   1---   = Feature 4 = On
----   -0--   = Feature 5 = Off
----   --0-   = Feature 6 = Off
----   ---0   = Feature 7 = Off

Thanks in advance,
Martin
