What about netflow ?

Dear ISP - you have made an accounting error that I am able to demonstrate in my copious traffic logs. Please credit $x to my account.

Dear Customer - our copious traffic logs indicate that you generated x traffic last month. Please pay $x net 30 days. Thank you.

Dispute resolution -- it's fun!

You don't say. Back in 2/95 I hit the following: CSCdi27509: Frame relay counters not updated when fast switching (it was fixed for 10.0. 10.2 and 10.3 fixes were being tested at the time). The MIB stats (inOctets, outOctets) were all wrong for FR subinterface customers. Cisco listed it as a sev=3 bug even though I argued that if ISPs are billing based on this info they may open themselves to a class action suit. Everyone inherently trusts the numbers coming out of your Cisco box. As we have seen bugs in all aspects of IOS code, some dormant for 10 years (see the recent remote crash telnet bug), one would have to independently verify that the numbers Cisco MIBs, netflow of whatever produce are correct, and this procedure would have to be done every time you upgrade to a new IOS version. Ever try doing that? And every time you add a new function you would have to go back and recheck (ever turn on FR traffic shaping and see what happens? :-)) Can of worms. -Hank
