Re: Can someone explain this?

The trouble with this, Dennis, so far as I can see, is that this box isn't UNIX - we have never had to think about clearing ARP on this box. I don't know if there is even a way to do it.

Perhaps that is accomplished by the system when restarting TCPIP - maybe with some other command.

This system, as you know, is positioned as not needing all that administrative stuff other OS' do.

So is there a way to clear the ARP? It'd be an interesting thing to know.

Thanks
Vern

It is a general rule-of-thumb in the unix world: If you replace a switch, clear ARP. If you replace a router, clear ARP. Seems to avoid a wealth of issues.

Ethernet cable, and the system went on running, telnet for sure.

However, the http servers no longer connected. This morning I
re-started all the HTTP servers, but we were still unable to connect.

I then did an IPL which brought everything back up.

In my experience, _every_time_ we unplug the Ethernet cable, we had
to at a minimum end and restart TCP/IP, and sometimes vary off and on
the controller...
ymmv...
