[nsp] 7500 problem with NAT+NetFlow?

[John Wong, Kok Seng]

Hi,

I've a 7507 router running IOS 12.1(13). We have several
serial lines connected to this routers & we're using
dynamic+static NATs. When i enabled Netflow switching on
the FasEthernet interface, somehow, all my NATs failed.
As these were live production sites, I did not take my
time to find out why... just removed NetFlow to get NAT
working! Any idea how come NetFlow can screw up NAT?

BTW, i tried to simulate the problem on a 3640 but
was not able to... which means it could be architecture
dependent?

Thanks.
