Is there a message in SYSOPR? One time when we lost power to the switch it
was hooked up to, the i didn't retry connecting.

I don't think a problem with arp tables can adequately explain why telnet
worked byt http didn't. Both telnet and http function above the network
layer which relies on the data link layer. If there was a problem with the
data link layer it would effect both of these protocols. Of course if it
was an arp table problem on a limited number of hosts and http and telnet
connections were not tried from the same host then it could be an arp table
issue.

I don't have any good ideas for what the cause would have been but I am
curious to know if you find out.

The system maintains an ARP (address resolution protocol) table that tells
it how to connect to other servers. My guess is that the ARP needed to be
refreshed. On a UNIX system that would be command:
arp -d
But I am unsure what command might do the equivalent on i.

Last night we put in all new switches, and quickly replugged the IBM i
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.
