A customer of mine is having some issues with NetFlow Data Export. When they enable it on one of their 6500, all have sup720, the CPU gets very busy. The CPU peaks att 90 - 95%, and averages at 75-80%.
If they disable NetFlow Data Export the CPU peaks at 10-15% and averages at 5-7,5%.
The 6504 is running Native IOS, version 12.2.25SXF, and i cant find any caveates in the release notes that would explain this behavoiur.
Could anyone try to help me to find out why this is and try to fix this.
