12.3.1.2
Autoconfiguration-noIFCP Boot
In this autoconfiguration boot modality, the dLAN 200 DSpro adapter has been
already configured (see Section 12.4 for more information) to successfully exe-
cute DHCP and TFTP so it skips IFCP.
12.3.1.3
NVRAM Boot
When a node starts in NVRAM mode, it collects all of the configured parameters
from the NVRAM memory and configures the firmware accordingly. There are
some basic parameters that are always configured in this mode:
쎲
GENERAL_TYPE: Node type – HE, CPE, or TDREPEATER.
쎲
GENERAL_IP_USE_DHCP: Use DHCP – yes or no. If this parameter is set to
no, the IP configuration parameters and the phone number are also confi-
gured from NVRAM.
All the other parameters are only configured if they have been downloaded from
a file first, and a
GENERAL_USE_AUTOCONF = no
line was in that autoconfi-
guration file. This is equivalent to performing a Save as Permanent.
12.4
IFCP Protocol
The IFCP (Inter Firmware Communication Protocol) is used to transfer the trans-
lation table between dLAN 200 DSpro adapters at booting.
Although the translation table is comprised mainly of VLAN parameters, cur-
rently there is one parameter that is not related to VLAN – the
TRANSLATION_ROOTPATH_OVLAN. In future releases, new parameters inde-
pendent of VLANs may be included in the translation table. Because of this, it
is advisable not to relate the IFCP only with the use of VLANs.
When a dLAN 200 DSpro adapter boots using autoconfiguration mode with the
current FW version, it
ALWAYS
performs IFCP requests if a byte allocated in the
NVRAM has not been written (by default the NVRAM is set to run the IFCP cli-
ent).
12.4.1
IFCP Booting
When a dLAN 200 DSpro adapter boots in autoconfiguration mode, it starts
sending IFCP requests. The dLAN 200 DSpro adapter needs to know if it is boo-
ting in a network with VLANs before requesting an IP through DHCP. For this
reason, and because the LV node does not know if communication to the MV
node is through PL or Ethernet, the FW-to-FW protocol uses a special IFCP MAC
