ACE module "Bad TCP cksum"

Hello,

We have the ACE module version:

build 3.0(0)A2(1.2)

I was wondering what could be the cause, when taking a capture in the ACE, to see some bad TCP cksum.

It seems so far, that only when taking a capture from the ACE that we can see that, and not when sniffing traffic, before and after the ACE.

any clue ?

Dan,

this is normal.

We capture the packet in a place where this is possible and this is done before the checksum is computed.
