Brian, What was it licensed for then? Here is some stuff I have found:
VxWorks - Appears to be used extensively in the MGX product lines and at least some of the content switches. In fact, I can find a number of articles about how to use VxWorks commands at the CLI As for QNX, you have http://www.cisco.com/warp/public/146/pressroom/1998/may98/16.html which seems to imply that it is used in some products as the real-time OS. Is it used in the PIX itself or under the IOS? Dunno, but it damned sure seems to be used somewhere. Wes Noonan, MCSE/MCT/CCNA/CCDA/NNCSS Senior QA Rep. BMC Software, Inc.
