Signature 6061 is not included with 2.2.1.8. This signature was released as part of 2.5(1)S2 as an early release of the S3 update. Due to it's last minute inclusion into S2, we were unable to include the documentation.
The html documentation will be included with the S3 signature updated to be released shortly. The html documentation can also be viewed online (as described in the S2 update README) at http://www.cisco.com/cgi-bin/front.x/csec/view.pl?VID=3186&VVID=4
