Title: 30-80% Failure on Pings

Tim,

What makes you think it's the AS/400 and not an issue on the Ethernet with an overloaded Collision domain ?? Are you using Hubs or Switches ? How much of your load is in the same Collision Domain as the iSeries ? If this is your busy time, it could be that your network not your AS/400 or maybe both are overloaded and that accounts for the loss of ICMP packets. Remember that a busy highway can only hold so many cars, just ask any rush hour Atlanta driver :-) An only a Token Ring network can guarantee packet deliver and quality !

Subject: 30-80% Failure on Pings

We have an overworked as/400. And we have a new one on order, but I was wondering if anyone has an idea for a Band-Aid?

Problem. If I ping a workstation during peak usage I will only get 2 of 5 successful hits...

Is there a way to grant more timeslices/priority to the IP services job, to prevent this problem? And if so, what job would I change?

Thanks, tim
