tion used to configure the master’s interface to the new user. However,
autoconfiguration also has a way to avoid using the RADIUS server if desi-
red. This consists of declaring a list of MACs, profiles and FW type in the
autoconfiguration file and using this list instead of RADIUS to authenticate
the users. See Sections 12.11 and 12.13 for more information.
If the node is the first dLAN 200 DSpro adapter in the network and connected
directly through the Ethernet port to the backbone, the autoconfiguration pro-
cess is different:
쐃
This node starts with the same default factory configuration: Access CPE;
쐇
Using DHCP protocol, each node gets its IP configuration (IP address, net-
mask and gateway) and the name of its corresponding autoconfiguration
file. There is also another parameter called ifcp-code that indicates if VLAN
is used and the value of the management VLAN if needed. Once this para-
meter is obtained the IFCP protocol finishes;
쐋
Using TFTP protocol, the nodes download the autoconfiguration file and
configure the firmware accordingly.
12.3.1
Autoconfiguration at dLAN 200 DSpro adapter Boot
When any node boots, there is a parameter stored in the NVRAM called
GENERAL_USE_AUTOCONF
. When this value is ‘yes’, the node boots in auto-
configuration mode and when ‘no’, it boots in NVRAM mode.
There are two autoconfiguration possibilities inside the autoconfiguration boot
mode depending on whether or not IFCP is performed.
12.3.1.1
Autoconfiguration-IFCP Boot
In this autoconfiguration boot modality, the node always initiates as a slave
(CPE) and starts to send IFCP requests. When this protocol ends, the dLAN 200
DSpro adapter has the minimum information to successfully connect to the
backbone and execute DHCP and TFTP.
The node then performs a DHCP request to get an IP configuration, the phone
number (if required) and the name of the autoconfiguration file, as well as the
TFTP server where the file is located. It then downloads the file and configures
the firmware accordingly.
