Hello guys ,
I am very confused that I got "Malformed Packet: GTPv2" in every Diameter (CCR) in version 1.6 .
I tried multiple versions of wireshark , I have found that for the same err_sample.pcap which I have already attached , there is
no such annoying prompt in version 1.2.16 . I read the WireShark manual , there is some explanation in this URL.
http://www.wireshark.org/docs/wsug_html_chunked/AppMessages.html#id622336 .
To my understanding , mostly there is something wrong in the packet content . Another proof is that other diameter packet is working
perfectly with wireshark 1.6.1 version .
Here comes my question : does this AVP(20600) finally caused the "malformed packet" prompt because there is no data in this AVP?
Or is there anything wrong with the CCR packet content ?
FYI : Diameter Server Port is 6555 , and this server connects the multiple clients.
