V7122 Gateway User Guide
Valid Range and Description
0 = Disable DHCP support on the gateway (default).
1 = Enable DHCP support on the gateway.
After the gateway is powered up, it attempts to communicate
with a BootP server. If a BootP server is not responding and
if DHCP is enabled, then the gateway attempts to get its IP
address and other network parameters from the DHCP
server.
After you enable the DHCP Server (from the Web
browser) follow this procedure:
•
Click the Submit button.
•
Save the configuration using the Maintenance
button (before you reset the gateway). For
information on how to save the configuration,
see Saving Configuration.
•
Reset the gateway directly (Web reset doesn't
trigger the BootP/DHCP procedure and the
parameter DHCPEnable reverts to '0').
Throughout the DHCP procedure the BootP/TFTP
application must be deactivated. Otherwise, the
gateway receives a response from the BootP server
instead of the DHCP server.
The DHCPEnable is a special 'Hidden' parameter.
Once defined and saved in flash memory, its
assigned value doesn't revert to its default even if
the parameter doesn't appear in the ini file.
0 = Disable LAN Watch-Dog (default).
1 = Enable LAN Watch-Dog.
When LAN Watch-Dog is enabled, the gateway's overall
communication integrity is checked periodically. If no
communication for about 3 minutes is detected, the gateway
performs a self test.
If the self test succeeds, the problem is logical link down
(that is, Ethernet cable disconnected on the switch side),
and the Busy out mechanism is activated if enabled
(EnableBusyOut = 1).
If the self test fails, the gateway restarts to overcome
internal fatal communication error.
Enable LAN Watchdog is relevant only if the
Ethernet connection is full duplex.
IP address of the primary DNS server in dotted format
notation.
IP address of the secondary DNS server in dotted format
notation.
