Hi,
Changing the chargecontrol.xml file to:
		<avp name="Volume-Quota-Threshold" code="869"
mandatory="must" may-encrypt="no" protected="may">
			<type type-name="Unsigned32"/>
		</avp>
Works for me.
 Quota-Holding-Time is defined in the dictionary.xml file and in the
chargecontrol.xml(as vendor specific)perhaps Volume-Quota-Threshold
Should be in both files as well. I think there is a bit of a mess with the
older 3GPP specs misusing
The common AVP's which has been corrected in later specs.
Best regards
Anders

Hi,

The cleared flag bits seem not to be the real problem that causes Wireshark
not to recognize this Volume-Quota-Threshold AVP. I removed the
‘vendor-id="TGPP"’ part from the related XML file line, and set
vendor-bit="mustnot". That did not help.
Furthermore, the 3GPP AVP Quota-Holding-Time, on the other hand, is
recognized without any problem, while all its flag bits are cleared too.

Regards,

Frederiek

Hi,
The problem is that Wireshark expects this to be a vendor AVP but it's sent
as a "normal" one.
I think this was changed in more recent versions of the 3GPP doc's to be
Vendor specific AVP:s.
 
The simplest soulution for you is to edit the XML file and remove
"Vendor-id="TGPP" " from the
relevant AVP:s
 
Best regards
Anders

Hi Anders,

Did you receive the sample file? Is the Volume-Quota-Threshold AVP
recognized in your case?

Regards,

Frederiek

Hi,
That should suffice, can you send me a small sample file?
Best regards
Anders

Hi,
 
The “Attempt to load/use Diameter XML Dictionary” checkbox, in the
preferences for Diameter, is checked.
The Diameter XML dictionary is set to “C:\Program
Files\Wireshark\diameter/dictionary.xml”.
 
The Volume-Quota-Threshold AVP (code 869) is not recognized. This AVP is not
defined by IETF RFC 3588, but by a 3GPP specification.
 
I am not that familiar with XML, though I noticed the occurrence of
following lines in file chargecontrol.xml:
 
<avp name="Volume-Quota-Threshold" code="869" mandatory="must"
may-encrypt="no" protected="may" vendor-bit="must" vendor-id="TGPP">
<type type-name="Unsigned32"/>
</avp>
 
I’m not sure whether this should be sufficient. It does not seem to be,
since the AVP is still not recognized.
 
Regards,
 
Frederiek

Hi,
AVP:s can be dissected either by the data in the file packet-diameter-defs.h
or by the Diameter
XML files if those preferences are set. See the wiki page for details.
The XML library is more updated than the file. What AVP:s are not
recognised?
 
Best regards
Anders

Hi,

I frequently use Wireshark to analyze Diameter protocol traffic. I
notice that not all AVPs are recognized. That is, the packet details
frame contains a line with "Unknown AVP" in that case. What must be done
to make Wireshark recognize these AVPs?

I am using the latest Wireshark version, i.e. version 0.99.5.

Regards,

Frederiek
