SECTION 3
Many conditions cause ARP reply failure, including the
following:
Your 6400 computer sent the ARP request to the LAN,
"
but the request did not reach the target host.
If your local LAN segment contains any repeaters or
bridges, and if any of these devices connects your 6400
computer to the remote host, problems with these
devices can cause ARP failure. Notify your system
administrator.
The ARP request successfully reached the target host
"
but was not read off the network by the target host's
network interface card, or your 6400 computer did not
receive the ARP reply.
This may indicate a problem with the network
interface card in the target host. Contact the
administrator of the remote host for help. This may
also indicate problems with intervening repeaters or
bridges. See your system administrator to investigate
any suspected problems with local repeaters and
bridges.
Also do the following:
Ensure ARP Server Mode is enabled for the access
"
point. For almost all installations, the No Flooding
setting is recommended.
