Using NBAR to block Kazaa2 traffic

We have a 3640 router running IOS 12.2. I am trying to use NBAR and QOS to block or tone down Kazaa2 traffic. I have the kazaa2 pdlm loaded into my config correctly and it shows up in the list when I do a ' show ip nbar protocol-discovery'. When I test it by downloading files with kazaa, NBAR does'nt seem to be 'discovering' any of the Kazaa traffic. Has anyone gotten this to work?

Re: Using NBAR to block Kazaa2 traffic

This is a known problem. Check the read me doc (NBAR_PDLM_Kazaa_v2_02_12_20_1.doc) on this problem and fix at http://www.cisco.com/cgi-bin/tablebuild.pl/pdlm

Re: Using NBAR to block Kazaa2 traffic

"1. The command “match protocol kazaa2 file-transfer *” might miss some of the data flows being tagged as file-transfer but will be classified as kazaa2, due to a corner case. For absolute control over direction of the file transfers, you must upgrade to a rebuild release of 12.2(13)T. [The fix is intended for release 12.2(13)T1.] "

How do I get a rebuild release of 12.2(13)T ? What does the 'T' stand for? Test?

Loaded IOS 12.2(13)T1 for my 3640, now it works!
