IP Testing (PING)
4-15
A Ping Response screen will appear, with the response from the ping. The
following responses may occur.
Ping Responses
■
<IPAddress> is alive
The PING was successful.
If a name was entered in the Ping page input field, the corresponding
IP address is displayed on the Response page.
■
PING: no route to host
A valid IP address or name was entered but the routing table does not
indicate how to reach the network that the IP address belongs to.
■
PING: host unreachable
This means that an ICMP response was received in response to the
PING, indicating that the PING failed because the IP address is
currently unreachable. This is indicative of a network problem. If the
router could not determine where to send the PING request, the PING:
no route to host error would have been generated. Since it was not,
the router sent the message either to the specific network to which
the IP address belongs or to a default gateway. If it was sent to the
specific network and the network was learned via RIP, there is
probably a temporary network problem. If the network is a static entry
in the routing table (entered by the user, for example), it may have
been entered incorrectly. If the network is not in the routing table and
the PING request went to a default gateway, then it may be that the
network is not supposed to be reachable so this is a reasonable result.
■
PING: timeout waiting for reply from <IP Address>.
The host network is probably reachable but there is no answer from
this IP Address. There are a couple of possible explanations for this.
The IP Address might not be assigned to any unit. The path from the
OfficeConnect Remote 840 to the unit is so slow that the PING
response did not get back in the allotted time frame. There may be a
temporary break in the path.
DNS Errors
■
Network Name: <name> could not be resolved.
■
Network Name: <name> could not be resolved due to a
problem interacting with the Name Server.
