User manual XC-32 XC-320 XC-4200
Xcell from the network
192.168.2.0
will transmit the DHCP requests from the two
machines back to the DHCP server (
192.168.1.1
). Both interconnected networks can thus
use the same DHCP server.
XI.3.2 - DHCP client
Xcell holds a DHCP client function. If a DHCP server is active on your network, Xcell can
receive its IP address and many others parameters from the DHCP server. In factory
configuration, Xcell boots with the DHCP mode active. The system
dhcp client mode
command enables you to select the running mode of DHCP client.
SYSTEM DHCP MODE <dhcp | bootp | none>
The
bootp
mode enables Xcell to act as a BOOTP client (Bootstrap Protocol). This
protocol, which is the predecessor of DHCP protocol, supports less options than DHCP.
To deactivate XC's DHCP client, use the
none
option.
Xcell does not know the DHCP server IP address. It broadcast is request on the LAN to
join the DHCP server. If you want to specify a particular DHCP server IP address, just use
the
system dhcp server
command.
Example :
ROOT>> system dhcp server 192.168.10.1
If you want to go back to the broadcast method, enter the following command :
ROOT>> system dhcp server 255.255.255.255
When Xcell is booting (if the DHCP client is active), it sends its DHCP request on the LAN
and waits for a reply. If it does not receive a reply after 30 seconds, Xcell assumes that
the request fails. Then, Xcell use IP address and other parameters saved in flash memory.
To modify the reply timeout, use the
dhcp clent timeout
command.
Example :
ROOT>> system dhcp timeout 60
WARNING !!
To validate DHCP commands, you must save new parameters in flash
memory. The next time Xcell will boot, it will use these new parameters.
XI.3.3 - DHCP relay
Xcell holds the function of DHCP relay. To activate this function, you just have to use the
system dhcp relay
command. This syntax command is the following :
-85-
