To create new user accounts, use the
SYSTEM

or
SYSTEM
ADD
LOGIN
commands. The accounts created
by these commands default to low privileges.
To change user privileges, use the

or

commands.
To list the current user or login accounts, use the

tively.
The user-related commands are details in

1.1.2.2 Access permissions to WEB interface
Similarly to CLI permission, the access to WEB interface is controlled by the user access level and by the
may-
configureweb
flag:
•
Default user
- can access to Status pages, Wireless configuration and user password settings. Cannot access
to the other configuration pages.
•
Engineer or Super user
- can access to Status , Wireless configuration, Security configuration, firmware
upgrade pages.
The following table maps the user properties to the corresponding WEB credentials. User properties can be
configured via CLI commands by setting the
user access level
(default, engineer, administrator) and the
mayconfig-
ureweb
flag (enabled, disabled).

1.1.2.3 Split management
Split management is part of the NMS provisioning framework.
Split management allows the end-user to perform configurations via WEB interface while the management of
the system is kept under the network administrator control (NMS).
When split management is enabled, a login user is created with login “admin” and default password “admin”.
The end-user can access to WEB
pages to configure wireless parameters and to change his own password.
The end-user cannot configure other system parameters like security, dhcpserver and he cannot execute firm-
ware upgrade. These configuration changes are still under the network administrator control.
When split management is disabled, the end-user doesn’t have access to the system WEB pages at all.

File system
The file system differs according to the gateway memory capacity and the presence or absence of an EEPROM.
There are three different file system cofigurations:
•
Gateways with 4Mbytes of FLASH (Fiber A, Fiber B, Fiber C)
•
Gateways with 8MBytes of FLASH with EEPROM (Modular, ADSL A)
•
Gateways with 8MBytes of FLASH without EEPROM (Fiber E, ADSL B, ADSL C)

The software running on the gateway is a multi thread application where
each task typically needs to load con-
figuration information when it starts, and store configuration changes for future use.
To support the above requirements, two dedicated file systems are provided. These are called the
In Store
File System
and the
Flash File System
. The two file systems provide a standard file interface to application
processes. These two file systems are referred to as
isfs
and
flashfs
respectively in this document. The
isfs
provides volatile run-time file storage whereas the
flashfs
provides non-volatile file storage. The flash memory
is partitioned according to sections
Section 1.1.3.1
and
Section 1.1.3.2
1.1.3.1 Gateway with 4Mbytes of FLASH
The file system on the gateway with 4 Mbytes fo FLASH is depicted in the
Figure 1-1

1.1.3.1.1 Boot partition
The
Boot ROM
program resides in a special partition (the
Boot Partition
) on the flash device. This is the first code
that runs when the system is started and provides self-test code as well as the ability to load the main run-time
images.
The boot partition cannot be read or written by the
flashfs process,
and typically doesn’t require upgrade. The
boot partition is automatically over-written when the gateway is upgraded using a flash image. In all other cases
the boot ROM program and boot partition are never altered.
1.1.3.1.2 Recovery partition
The
Recovery Partition
is a reserved partition on the flash device where a minimal operating system named
Recovery Application code
is installed. This operating system runs only if the boot ROM code is not able to

start the main application code because, if for example the main partition has been corrupted by a system
power-off during software upgrade.
Services available in the Recovery Application Code are a subset of those available in the Main Application
Code: for example VoIP modules, SSH and SNMP access are not available.
Note:
Recovery Application Code uses the same configuration file as the Main Application Code. Configuration
parameters for modules not available on Recovery Application Code are simply ignored when the CPE
runs in recovery mode.
1.1.3.1.3 Main partition
The gateway operating system is named
Main Application code
and is stored in a third
flashfs
partition area (the
Main Partition
) that provides permanent storage for the
Main Application code,
and for files that are normally used
only during system bootstrap.
During the system bootstrap the files stored in the main partition are copied into
isfs
in order to make them
available to all application processes. Processes typically use the
isfs
to store temporary configuration data.
The configuration is stored within the main partition.
1.1.3.2 Gateway with 8MBytes of FLASH with and without EEPROM
The main difference between models with and without the EEPROM is the location of unit-specific information
like MAC address, serial number, model name etc.
Figure 1-2
below depicts the two different partitions side-by-side. 8 MByte Flash Memory partitioned with and

for example VoIP modules, SSH and SNMP access are not available.
