Re: Clear ARP cache

Thanks Bryan, Larry posted the code I needed as well.

After investigation we found out that the ARP did need to be cleared, but,
more importantly we found out firewall rules had been applied since the
last test to "tighten things up" and the rules only allowed the main
interface address and dropped packets from the other four addresses used by
this system. Now I have to wonder what other interesting things will just
stop working in the future......

Years ago I came across a program to clear the ARP cache on IBM i. Try

as

I might, I can't even find an article on it. The reason we have to clear
the ARP is after one of 5 partitions switch from prod to HA, the other

four

partitions ignore DNS and still try to communicate with the prod IP
address, which due the switch has changed. I cleared the ARP cache using
the old iNavigator, but since iNavigator will be going away, and we would
like to automate the process, I need a program.

Anyone have this little gem?
