Not able to add avp

  • retag add tags

Hi I have a AVP from vendor ALU. I tried to add it in dictionary.xml but still it is shown as unknown. The avp details are:

<attribute code="1139"
           vendorName="ALU"
           name="Subscriber-User-Id"
           format="UTF8STRING"
           mFlag="OPTIONAL"
           pFlag="OPTIONAL"
           vFlag="REQUIRED"
           encrypt="true"
           register="true"
           proprietary="true"/>

What I have added in xml is:

<avp name="Subscriber-User-Id" code="1139" mandatory="v" vendor-bit="must" may-encrypt="no" protected="may" vendor-id="ALU">
    <type type-name="UTF8String"/>
</avp>

As seen in the Bug answer it works with the modified xml file now part of Wireshark.

Is it a config issue that I was not able to do or you corrected something in the build that was mentioned there ?

I just added the code from my comment, you can look at the AlcateLucent.xml file from the installer I linked. So No, nothing special done.

What version of Wireshark are you using? Recent version has an AlcatelLucent.xml where you should add the AVP. Your format is slightly off, should be:

    <avp name="Subscriber-User-Id" code="1139" mandatory="mustnot" vendor-bit="must" may-encrypt="no" protected="may" vendor-id="ALU">
    <type type-name="UTF8String"/>
</avp>

It was a copy paste mistake where "v" is shown.

I tried the same as suggested by you but no success.

Wireshark version: Version 2.6.3 (v2.6.3-0-ga62e6c27)

So you added those lines to AlcatelLucent.xml in the diameter directory and restarted Wireshark but still the AVP is not dissected?

YEs, I added the same as suggested in AlcatelLucent.xml in the diameter directory and restarted Wireshark but still the AVP is not dissected. Are there any wireshark logs that are generated when it dissect the pcap ? In case it needs to be enabled then I can do so to figure out any debug information.

If you can upload a packet with the AVP somewhere we could have a look.

Anders's avatar Anders (2018-09-10 14:40:03 +0000) edit

Is there any location where I can upload the same ?
