If using the ZyWAN as a DHCP Server to the PC:
•
Make sure the PC
Dhcp Enabled
is set to
Yes
.
•
Make sure that the PC has been given a proper address from the ZyWAN,
according to how it’s configured.
If using the PC in a fixed address mode, check the address and make sure that it is
compatible with the address and subnet necessary to communicate on the network or
direct to the ZyWAN, depending on the test being performed.
If the ZyWAN is acting as a DHCP Server to the PC and is configured to serve the DNS
addresses, these should be displayed in the ipconfig settings.
Log into ZyWAN COM1 for diagnostics
When using a null modem serial cable connected to COM1, as described in
Initial
configuration over a network
on page
28
, several commands can be issued to the
ZyWAN to diagnose network configuration or operation.
To check network configuration or availability:
ifconfig
To set a temporary network address on an interface:
ifconfig eth1
ip_address
netmask
subnet
where
ip_address
is the actual address on the network,
and
subnet
is the subnet mask in dotted notation (such as 255.255.0.0).
To send a diagnostic message to another device on a network:
ping address
where
address
is the numeric or named address of another device.
Press
Ctrl-C
to stop the ping.
To check the route table of the ZyWAN:
route -n
To make a TCP/IP connection to a port on a device:
nc ip_address ip_port
where
ip_address
is the device address on the network or 127.0.0.1
for the ZyWAN itself,
and
ip_port
is the network port.
Check with network administrator
If you are still unable to get the ZyWAN to connect to an existing network, check with a
network administrator for additional support.
