I am having an issue with retrieving the value for the field radius.Framed_IP_Address but all other fields seem to be returned fine.

Here is the command I'm running and sample output.

$tshark -i eth1 -T fields -e radius.Event_Timestamp  -e radius.User_Name  -e radius.Acct_Status_Type -e radius.Acct_Session_Id -e radius.Calling_Station_Id -e radius.Framed_IP_Address -E separator="|"

I have confirmed that there is a value for the AVP for Framed-IP-Address by viewing the output. All other fields seem to work and I have tried using both radius.Framed_IP_Address and radius.Framed-IP-Address with no success.

is there any reason why only this field doesn't seem to work?

-e radius.Framed-IP-Address works with tshark 1.8.4 on Windows XP, while reading these capture files:

it could be a bug in your tshark version. What is the output of tshark -v on your system?
it could be a typo in your command. Did you really try -e radius.Framed-IP-Address?

Thanks Kurt,

I just ran it using one of the input file you supplied with the command:

tshark -r radius-acct-no-dups-sample.pcap -T fields -e radius.Framed-IP-Address

This works and returns the IP addresses. It only seems to not be working when I am trying to capture from the interface.

It only seems to not be working when I am trying to capture from the interface.

does it work, if you capture from the interface and write to a file. Then, afterwards read from that file with tshark?

I just want to check if it's the live capturing or a 'problem' with the radius protocol in your environment.

If does work that way, it might be a bug in tshark. Then, please file a bug report at Please add a detailed problem description and a link to this question.
