1.2.3.1.13 WEBSERVER SET TELNETSECCLASSES

Syntax

WEBSERVER SET TELNETSECCLASSES <SECCLASSES>

Description

This command allows you to set the security class(es) associated with the Telnet AppS-

ervice. Entering this command will overwrite any existing security class(es) configured

for the Telnet AppService. This has the same effect as entering the command ip set apps-

ervice telnet secclasses <secclasses>.

Options

The following table gives the range of values for each option that can be specified with

this command and a default value (if applicable).

Option

Description

Default Value

SECCLASSES

Supported secclasses values are as follows:

all- allows access to the HTTP AppService via all exist-

ing security interfaces

none- prevents access to the HTTP AppService via any

existing security interface

internal- allows access to the HTTP AppService via the

existing internal security interface

external- allows access to the HTTP AppService via the

existing external security interface

dmz - allows access to the HTTP AppService via the

existing dmz security interface

To allow access to the HTTP AppService via two secu-

rity interface types, type the secclass values separated

by a comma (for example, internal, external) or sepa-

rated by a space and enclosed in double-quotation

marks (for example, “internal external”).

To specify all three internal, external and dmz sec-

classes, use the all value.

Emergency

This chapter describes the AT-iMG600 emergency module used to configure the system connectivity when the

intelligent Multiservice Gateway runs in recovery mode. Emergency module is available only on AT-RG613 and

AT-iMG616.

1.3.1

Introduction

If the intelligent Multiservice Gateway flash file system is corrupted, the system will start running a minimal

operating system simply named

recovery

.

From the recovery mode, it’s possible load remotely the complete system application image and any additional

file to recover the unit into a full operative default system configuration.

1.3.2

Emergency configuration

The connectivity between the intelligent Multiservice Gateway and the remote network operation centre

(NOC) can operate both via any intelligent Multiservice Gateway Ethernet port and via the ADSL port.

Emergency

Save and activate emergency configuration.

iMG/RG Software Reference Manual (System Configuration)

1-48

When Ethernet connection is used, the intelligent Multiservice Gateway Ethernet ports are set to belong to

the default vlan as untagged port. When running in recovery mode, there is no support to tagged VLANs on

the Ethernet interfaces.

When ADSL connection is used, the intelligent Multiservice Gateway tries to connect to the remote NOC via

an RFC1483 LLC/SNAP Bridged connection type with VPI/VCI = 0/35 without any tagging scheme.

It’s possible configure the IP address used to connect remotely to the intelligent Multiservice Gateway when

recovery application is running.

To set a static IP address use the

EMERGENCY SET IPINTERFACE IPADDRESS NETMASK

command

and to set the default gateway use the

EMERGENCY SET IPINTERFACE GATEWAY

command.

To set a dynamic IP address uses the

EMERGENCY SET DHCP ENABLE

command. The intelligent Multi-

service Gateway will get the IP address from any external DHCP server as well as the interface subnet and the

default gateway.

Note:

Note that if no DHCP server is discovered, the intelligent Multiservice Gateway will use the autoip

feature to autonomously assign a random IP address in the range 169.254.0.0/16. If a DHCP server

becoms available later, the IP interface will then change the IP address to the value offered by the DHCP

server.

1.3.3

Save and activate emergency configuration.

The emergency configuration data set in the previous section is not active until saved permanently in the intel-

ligent Multiservice Gateway e2prom. Emergency configuration data are saved in an e2prom instead in the

flashfs filesystem to increase the system robustness to any flashfs failure.

To save emergency configuration data in e2prom use the

EMERGENCY UPDATE

command.

Emergency configuration data is also saved in the system configuration any time the command

SYSTEM CON-

FIG CREATE or SYSTEM CONFIG SET

are entered. In this way the information is stored in two differ-

ent areas: the e2prom and the file bootstrap configuration file in the main partition.

In the case where the system starts in recovery mode because the main application partition is considered cor-

rupted, only the information stored in the e2prom will be used to configure the recovery application.

During normal system bootstrap initialization the recovery configuration data stored in the bootstrap configu-

ration file is considered the current emergency settings. This information is also stored automatically in the

e2prom to be immediately active.

To display the active recovery configuration data use the

EMERGENCY SHOW

command.

To avoid any misalignment between the configuration stored in the E2PROM and the configuration reported in

the bootstrap configuration file, the following situations are managed during the system bootstrap:
