IPDACT-2(UD) - Configuration
III-21
Doc.DM385-I
Rev. 4.0
access routers (in ADSL for example) have the possibility to act as a DHCP
server, therefore in these environments, start up is immediate.
The IPDACT-2(UD) functioning mode is as follows: when the device boots up,
it tries to dynamically obtain the IP configuration from any DHCP server which
is in the network. If this is achieved, it activates the said configuration and
displays a message on the console.

Address assignment in the DHCP protocol is defined so that this can be
permanent or expire after a certain period of time (configurable in the DHCP
server). If the assignment is permanent, the IPDACT-2(UD) will not renew the
address until the next time it is rebooted. Contrariwise, before the validity of
the address times out, the IPDACT-2(UD) will automatically request the server
to renew the assignment.
If during the first attempt (or during the renewal attempt) the IPDACT-2(UD)
cannot get the IP address from a DHCP server, and with the aim of not
leaving the device without IP connectivity, the device will use the IP
parameters which have been statically configured in the device console and
will operate with these parameters until the next time the IPDACT-2(UD) is
restarted. Therefore, if you need to force the IPDACT-2(UD) to renegotiate an
address, you will need to reboot.
The following message is displayed by the IPDACT-2(UD) on console if it
cannot obtain an assignment through DHCP.

From release 2.2 onwards, the DHCP client can be enabled/disabled. In the
previous releases this was always operating. In the default configuration it is
enabled. To enable/disable the client, enter the IPDACT-2(UD) generic
configuration:
