Known Affected Releases

12.0(32)SY2 12.0S

Description (partial)



Linecards of Cisco router's running distributed CEF with Netflow enabled may have the origin AS 
field set to zero even though it is set correctly on the RP. This will result in the origin AS 
being reported as zero in most flow records associated with that prefix.

This inconsistency will be picked up by the CEF inconsistency checkers if fib entry data content 
checking has been enabled with

<CmdBold>ip cef table consistency-check data<noCmdBold>

Note: this inconsistency will only affect Netflow reporting and will never result in misforwarding 
of packets by CEF.


The problem can occur in any release except for 12.2(25)S or later and any release based on this 
such as the SX,SXF, and SB releases.
