To create new user accounts, use the

SYSTEM

ADD

or

commands. The accounts created

by these commands default to low privileges.

To change user privileges, use the

commands.

To list the current user or login accounts, use the

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.

1.1.3

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

FIGURE 1-1

4 MByte Flash Memory partitions

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.
