- We have also had occasion to need UDP checksumming (during a problem
- with a router). Upon investigation we found that there is no standard
- way in AIX to do this. We were, however, able to get a patch from
- Austin technical support which turned UDP checksumming on.
-
- The problem with this was that it was just a patch and not a part of
- standard AIX. This made it somewhat difficult to use. Based on
- our experience, we opened a PMR requesting this feature be added to
- standard AIX. So far we have had not action on our PMR.
-
- My suggestion is as follows:
-
- 1) For your immediate need- talk to tech support and see if you can
- get a patch for your level of the system which allows you to turn
- it on.
-
- 2) For everyone's long term benefit, open a PMR requesting it be made
- standard like we did. I believe the only way we can ever get this
- to happen is if enought people request it.
-
- If you want additional info on our experience, please email me.
