• DHCP IP address Server Failure. If the DHCP server fails, the
Xenta 913 cannot retrieve its addresses, and as a result will use a
temporary IP address.
• Maintenance. Each Xenta 913 may require an individual address
reservation in the DHCP server. Creating these address reserva-
tions typically includes collecting the MAC IDs from each
Xenta 913. Replacing an Xenta 913 requires changing the DHCP
reservation as well. The use of redundant DHCP servers requires
replicating DHCP reservations.
• Address lease (without reservation). The DHCP server delivers IP
addresses for a certain period of time, that is, an address is leased
by the Xenta 913. When the lease time runs out, the Xenta 913
tries to renew the address lease. If the address is not reserved for
the Xenta 913 with a certain MAC ID, the device might receive a
different IP address.
If you decide to use DHCP, you must decide whether your Xenta 913
should have a statically or a dynamically DHCP-provided IP address.
A static address does not change every time the Xenta 913 restarts and
is manually configured. DHCP servers typically do not provide static
addresses, but they can generally be configured to do so.
If your Xenta 913 needs a static address, your network administrator
must create an individual address reservation in the DHCP server, using
the Ethernet MAC ID of the Xenta 913.
To use DHCP on the Xenta 913, you must enable it from either the ter-
minal connection using the setip command or from the TCP/IP config-
uration page in the web interface.
The DHCP server must be configured to provide at least the following
information:
• IP address
• Subnet
and preferably:
• Default gateway
• DNS (optional)
Note
• If a dynamic reservation is made by the DHCP IP address server,
it has to update the DNS with the address leased to the
Xenta 913.
