About FortiBridge

Introduction
This chapter introduces you to the FortiBridge-1000 and FortiBridge-1000F
products that provide fail open protection for FortiGate Antivirus Firewalls
operating in transparent mode. Fail open protection keeps network traffic flowing
in the event of a FortiGate unit failure. This chapter contains the following topics:

About FortiBridge
The FortiBridge products are a solution for enterprise organizations to provide fail
open protection for FortiGate units deployed inline in transparent mode. The
FortiBridge products use multiple probe protocols to detect failures in the
FortiGate unit. FortiBridge zero power fail open technology means that the
FortiBridge unit also fails open if a power failure occurs.

A FortiBridge unit functions as a pass-through device when a FortiGate unit or
FortiGate HA cluster operating in transparent mode fails or loses power. The
FortiBridge unit bypasses the FortiGate unit to make sure that the network can
continue processing traffic. The FortiBridge unit is not a firewall or antivirus
device. FortiGate services are not applied when the FortiBridge unit bypasses
traffic.

FortiBridge operating principles

Example FortiBridge application

FortiBridge operating principles
This chapter describes a typical transparent mode FortiGate network and how to
add a FortiBridge unit to this network to provide fail open protection. This chapter
also contains detailed information about how FortiBridge units operate and
concludes with descriptions of adding a FortiBridge unit to an HA cluster and
connecting a FortiBridge unit other FortiGate interfaces.
This chapter contains the following sections:
•

Example FortiBridge application

•

Normal mode operation

•

Bypass mode operation

•

FortiBridge power failure

•

Example FortiGate HA cluster FortiBridge application

•

Example configuration with other FortiGate interfaces

Example FortiBridge application
A typical application of a FortiGate unit operating in transparent mode is to insert
the FortiGate unit into an internal network, between the network and the router
that connects the network to the Internet. In this configuration, the FortiGate unit
can provide security services for all traffic passing between the internal network
and the internet. These security services can include:
•

applying firewall policies and IPS attack prevention to all traffic,

•

applying virus scanning to HTTP, FTP, POP3, SMTP, and IMAP traffic,

•

applying web filtering to HTTP traffic,

•

applying Spam filtering to POP3, SMTP, and IMAP traffic.

The internal network is connected to the FortiGate unit internal interface. The
router is connected to the FortiGate unit external interface. The FortiGate unit can
be added to the network without changing the configuration of the network (except
to add the FortiGate management IP address).
Figure 2: Example transparent mode network

(Transparent mode)

To allow users on the internal network to connect to resources on the Internet, add
Internal -> External firewall policies to the FortiGate unit. Add protection profiles
to the firewall policies to apply security services such as virus scanning, web
filtering, spam filtering and IPS to the traffic that passes through the FortiGate unit.

Example FortiBridge application

FortiBridge operating principles

The FortiGate unit acts as an extra layer of protection for your internal network.
While it is operating, the FortiGate unit protects the internal network from threats
originating on the Internet. All users on the internal network connect through the
FortiGate unit to the Internet. This also means that if a failure or other interruption
caused the FortiGate unit to stop functioning, users on the internal network would
not be able to connect to the Internet.
You can install a FortiBridge unit to maintain internet connectivity for the internal
network if the FortiGate unit stops functioning. The FortiBridge unit provides fail
open protection for your network by bypassing the FortiGate unit if a failure
occurs.

Connecting the FortiBridge unit
Operating in normal mode, the FortiBridge unit functions like a layer-2 bridge,
passing all traffic to the FortiGate unit. The FortiGate unit processes the traffic,
which then passes through the FortiBridge unit again and then to its final
destination.
In most cases, you do not have to make changes to the FortiGate unit
configuration or to the network to add a FortiBridge unit. The only network
requirement for FortiBridge is the availability of a single management IP address
for the FortiBridge unit. The FortiBridge management IP address is required in
addition to the FortiGate management IP address.
The connection procedure is different depending on whether the FortiBridge unit
uses copper gigabit ethernet network connections or fiber gigabit ethernet network
connections. This section includes the following connection procedures:
•

Connecting the FortiBridge-1000 (copper gigabit ethernet)

•

Connecting the FortiBridge-1000F (fiber gigabit ethernet)

Connecting the FortiBridge-1000 (copper gigabit ethernet)
The FortiBridge-1000 unit contains 4 auto-sensing 10/100/1000 Ethernet
interfaces that connect to the internal and external networks and to the FortiGate
interfaces that were connected to these networks. Use the following steps to
connect a FortiBridge-1000 unit to the network as shown in Figure 3.
Note: Normally, you would use straight-through ethernet cables to connect the
FortiBridge-1000 unit to the FortiGate unit and to your networks. However, for some
connections you may need a crossover ethernet cable (for example, for compatibility with
network devices that do not support Auto MDI/MDIX).

Connecting the FortiBridge-1000F (fiber gigabit ethernet)
The FortiBridge-1000F unit contains 4 multimode fiber optic gigabit interfaces that
connect to the internal and external networks and to the FortiGate interfaces that
were connected to these networks. Use the following steps to connect a
FortiBridge-1000F unit to the network as shown in Figure 3.

Connect the FortiBridge-1000F INT 2 interface to the FortiGate internal interface.

Connect the FortiGate external interface to the FortiBridge-1000F EXT 2
interface.

Connect the internal network to the FortiBridge-1000F INT 1 interface.

Connect the FortiBridge-1000F EXT 1 interface to the router.

Normal mode operation
If the FortiGate unit is operating normally, the FortiBridge unit operates in Normal
mode. Traffic from the internal network enters the FortiBridge INT 1 interface then
exits the INT 2 interface to the FortiGate unit. The traffic from the FortiBridge
INT 2 interface enters the FortiGate internal interface. Firewall policies and
protection profiles are applied to the traffic by the FortiGate unit. Accepted traffic
then exits the FortiGate External interface and enters the FortiBridge EXT 2
interface. The traffic then exits the FortiBridge EXT 1 interface and goes to the
external network. Traffic from the external network reverses this sequence.

How the FortiBridge unit monitors the FortiGate unit
To monitor the FortiGate unit for failure, you must enable probes on the
FortiBridge unit. When you enable a probe, the FortiBridge unit sends packets
from the FortiBridge INT 2 interface, through the FortiGate unit to the FortiBridge
EXT 2 interface. If the EXT 2 interface receives the probe packets, the FortiGate
unit is operating normally. If the EXT 2 interface does not receive probe packets
the FortiBridge unit assumes that the FortiGate unit has failed.

Probe packets

(Transparent mode)

You can enable ICMP (ping), HTTP, FTP, POP3, SMTP, and IMAP probes to test
connectivity through the FortiGate unit for each of these protocols. The
FortiBridge unit simultaneously tests connectivity through the FortiGate unit for
each probe that is enabled.
The first probe that registers a failure causes the FortiBridge unit to stop sending
all probe packets. The FortiBridge unit responds to the failure according to the
action on failure that you configure. The action on failure can include fail open,
send alert email, send a syslog message, and send an SNMP trap. You can
enable any combination of these actions on failure. Fail open switches the
FortiBridge unit to bypass mode. Other actions on failure alert system
administrators that the FortiBridge has determined that a failure occurred.

Probes and FortiGate firewall policies
Probe packets are accepted and passed through the FortiGate unit by firewall
policies added to the FortiGate unit. When enabling probes, you must make sure
that the firewall policies added to the FortiGate unit can accept probe packets. For
example, if your FortiGate unit does not accept FTP packets, you should not
enable the FTP probe. Table 1 describes FortiGate firewall policy requirements for
each FortiBridge probe.

Enabling probes to detect FortiGate hardware failure
A FortiGate unit can stop processing network traffic because of a hardware failure
such as the failure of a hardware component, a loss of power, or a loss of
connectivity if a network cable is unplugged.
If a hardware failure occurs, the FortiGate unit stops processing all traffic. You can
enable any FortiBridge probe for the FortiBridge unit to detect a FortiGate
hardware failure.

Enabling probes to detect FortiGate software failure
A FortiGate unit can also stop processing network traffic because of a software
failure. For example, a firmware issue could cause a specific software process to
crash. Also, network traffic could increase to a point where the FortiGate unit
cannot process all traffic. As a result, the FortiGate unit could stop processing
some or all traffic without a hardware failure occurring.
To detect a FortiGate software failure, you can enable probes for FortiGate
services that you want to provide fail open protection for. For example, if it is a
high priority for your network to provide SMTP email services, you should enable
the SMTP probe. If the SMTP probe detects a failure of SMTP traffic through the
FortiGate unit, the FortiBridge unit switches to bypass mode to maintain SMTP
traffic flow.
If you do not consider FTP traffic a high priority, you can leave the FTP probe
disabled. In this configuration, if only FTP traffic fails, the FortiBridge does not
switch to bypass mode.

Probe interval and probe threshold
For each probe, you set a probe interval and a probe threshold. The probe interval
defines how often to test the connection. The probe threshold defines how many
consecutive failed probes can occur before the FortiBridge considers the
connection to have failed.

Bypass mode operation

FortiBridge operating principles

Bypass mode operation
When the FortiBridge unit operates in bypass mode, the FortiBridge INT 1 and
EXT 1 interfaces are directly connected. All traffic between the internal and
external network segments flows, whether or not the FortiGate unit is operating
normally.
Because the INT 1 and EXT 1 interfaces are directly connected, you cannot use
Telnet or SSH to connect to the FortiBridge CLI. Instead you must use a console
connection.
The FortiBridge unit remains in bypass mode even if the FortiGate unit recovers.
To restore the FortiGate unit, you must manually switch the FortiBridge unit back
to normal mode. You can switch the FortiBridge unit to normal mode by pressing
the mode switch on the FortiBridge front panel or by using a console connection to
the CLI and entering the command execute switch-mode. You can also use
the mode switch and the execute switch-mode command to manually switch
the FortiBridge unit from normal mode to bypass mode.
Figure 6: FortiBridge unit operating in bypass mode
(Bypass mode)
Internal network

INT 2

(Transparent mode)

When the FortiBridge unit is operating in bypass mode you can still connect to the
FortiBridge CLI and manage the FortiBridge unit (for example to switch the
FortiBridge unit to normal mode). When the FortiBridge unit operates in bypass
mode, you cannot connect to the FortiGate interfaces that are connected to the
FortiBridge unit.

FortiBridge power failure
If a power failure occurs and the FortiBridge unit loses power, zero power fail open
technology causes FortiBridge unit to fail open. The FortiBridge unit bypasses the
FortiGate unit and all traffic passes between the FortiBridge INT 1 and EXT 1
interfaces. If power is restored to the FortiBridge unit, it starts up in bypass mode
and then switches to normal mode when its start up sequence is complete,
reconnecting the FortiGate unit to the network.
Note: The FortiBridge-1000F contains a battery to keep the fibers lit in fail open mode. If
the FortiBridge-1000F unit loses power, the battery will power the fail open condition for
approximately three hours. When power is restored, the battery requires approximately
three hours to recharge if completely drained. The FortiBridge-1000 unit does not use a
battery and can maintain a fail open condition indefinitely.

FortiBridge operating principles

Example FortiGate HA cluster FortiBridge application

Example FortiGate HA cluster FortiBridge application
A FortiBridge unit can provide fail open protection for a FortiGate HA cluster
operating in transparent mode in much the same way as for a standalone
FortiGate unit. To provide fail open protection for an HA cluster, connect the
FortiBridge unit to the switches that connect the internal and external interfaces of
the cluster. Use the following steps to connect a FortiBridge unit to the HA cluster,
as shown in Figure 7:

HA cluster

(Transparent mode)

The network configuration and FortiBridge configuration are the same for a cluster
and for a standalone FortiGate unit. In normal mode, packets pass through the
FortiBridge unit and through the FortiGate HA cluster and back through the
FortiBridge unit. For the cluster to process this traffic, you must add
Internal -> External firewall policies to the cluster configuration. If a failure occurs
and the cluster no longer processes traffic, the FortiBridge unit switches to bypass
mode, bypassing the cluster.
The connection procedure is different depending on whether the FortiBridge unit
uses copper gigabit ethernet network connections or fiber gigabit ethernet
network connections. This section includes the following connection procedures:
•

Connecting the FortiBridge-1000 (copper gigabit ethernet)

•

Connecting the FortiBridge-1000F (fiber gigabit ethernet)

Connecting the FortiBridge-1000 (copper gigabit ethernet)
The FortiBridge-1000 unit contains 4 auto-sensing 10/100/1000 Ethernet
interfaces that connect to the internal and external networks and to the cluster
interfaces that were connected to these networks. Use the following steps to
connect a FortiBridge-1000 unit to the network as shown in Figure 7.
Note: Normally, you would use straight-through ethernet cables to connect the
FortiBridge-1000 unit to the FortiGate unit and to your networks. However, for some
connections you may need a crossover ethernet cable (for example, for compatibility with
network devices that do not support Auto MDI/MDIX).

Example configuration with other FortiGate interfaces
All of the examples in this chapter describe using the FortiBridge unit to provide
fail open protection for traffic passing between the FortiGate unit internal and
external interfaces. You can actually use a FortiBridge unit to provide fail open
protection for any two FortiGate unit interfaces. No limitation is implied by naming
the FortiBridge interfaces INT and EXT. These names are used to simplify
installation procedures. Figure 8 shows a FortiBridge-1000 unit providing fail open
protection for network traffic between ports 5 and 6 of a FortiGate-500A unit.

the IP address of the TFTP server is 192.168.1.23, enter:
execute restore image FBG_1000-v10-build010-FORTINET.out
192.168.1.168
The FortiBridge unit uploads the firmware image file. Once the file has been
uploaded a message similar to the following is displayed:
Get image from tftp server OK.
This operation will downgrade the current firmware version!
Do you want to continue? (y/n)

Type Y.
The FortiBridge unit reverts to the old firmware version, resets the configuration to
factory defaults, and restarts. This process takes a few minutes.

Reconnect to the CLI.

To confirm that the older version of the firmware image has been loaded, enter:

Installing FortiBridge unit firmware

Installing firmware from a system reboot
This procedure installs a specified firmware image and resets the FortiBridge unit
to default settings. You can use this procedure to upgrade to a new firmware
version, revert to an older firmware version, or to re-install the current firmware.
To use this procedure you:
•

access the CLI by connecting to the FortiBridge console port,

•

install a TFTP server that you can connect to from the FortiBridge EXT 2
interface. The TFTP server should be on the same network as the EXT 2
interface. The FortiBridge unit cannot access the TFTP server if its behind a
router.

During this procedure you will be asked to enter a local IP address for the
FortiBridge unit. This is a temporary address used for downloading the firmware
image.
This procedure reverts your FortiBridge unit to its factory default configuration.
Before running this procedure you can backup the FortiBridge unit configuration
using the command execute backup config.
To install firmware from a system reboot
1

Connect to the CLI using the FortiBridge console port.

Make sure the TFTP server is running.

Copy the new firmware image file to the root directory of the TFTP server.

Make sure the EXT 2 interface of the FortiBridge unit can connect to the TFTP
server.

Enter the following command to restart the FortiBridge unit:
execute reboot
As the FortiBridge unit starts, a series of system startup messages are displayed.
When the following messages appears:
Hit any key to stop autoboot:

Immediately press any key to interrupt the system startup.
Note: You only have 3 seconds to press any key. If you do not press any key soon enough,
the FortiBridge unit reboots and you must log in and repeat the execute reboot
command.

When you successfully interrupt the startup process, the => prompt appears:

Configuration and operating
procedures
This chapter describes how to configure a FortiBridge unit to provide fail open
protection for a FortiGate unit operating in transparent mode. This chapter also
describes some commonly required FortiBridge operating procedures such as
recovering from a fail open event, manually switching between FortiBridge
operating modes and backing up and restoring the FortiBridge configuration.
The procedures in this chapter assume that you have connected the FortiBridge
unit to your network and completed its basic configuration as described in “Setting
up FortiBridge units” on page 19.
Note: The information in this chapter can be applied to any standalone FortiGate
transparent mode network configuration. These procedures can also be applied to a
FortiBridge unit providing fail open protection for a FortiGate HA cluster operating in
transparent mode.

Configuring FortiBridge probes
To monitor a FortiGate unit for failure, you configure the FortiBridge unit to send
probe packets through the FortiGate unit. Using probe packets, the FortiBridge
unit can confirm that the FortiGate unit can process ICMP (ping), HTTP, FTP,
POP3, SMTP, and IMAP traffic. Until you configure probes, the FortiBridge unit
cannot detect if the FortiGate unit has failed.

Configuring FortiBridge probes

This section describes:
•

Probe settings

•

Enabling probes

•

Verifying that probes are functioning

•

Tuning the failure threshold and probe interval

Probe settings
Configure probe settings to control the response when a FortiBridge probe
detects that the FortiGate unit has failed. Probe settings consist of:
Table 11: Probe settings
Probe Setting

Description

Action on failure

Set the FortiBridge unit response when a probe detects that fail open
the FortiGate unit has failed. The FortiBridge unit can.
• Send alertmail
•

Fail open

•

Send an SNMP trap

Default

• Send a message to a syslog server
You can add up to four actions on failure. All of the
configured actions on failure occur when the FortiBridge
unit detects a failure.
Dynamic IP
pattern

Configure the INT 2 and EXT 2 interfaces with dynamic
(none)
probe IP addresses. The dynamic probe IP addresses
should not conflict with IP addresses on the network that
the FortiGate unit is connected to. These IP addresses are
not visible from the outside network, but they should not
conflict with IP addresses in packets passing through the
FortiBridge unit. You cannot change the dynamic IP pattern
if any probes are enabled.

FortiGate unit
serial number

The serial number of the FortiGate unit that the FortiBridge (none)
unit is connected to. The serial number appears in
FortiBridge alert mail, and syslog messages to identify the
FortiGate unit.

To configure probe settings
This procedure shows how to configure the following probe settings:
•

The FortiBridge unit responds to a FortiGate unit failure by failing open and by
sending an alert email, a syslog message, and an SNMP trap

•

The dynamic IP pattern is 2.2.2.*

•

The FortiGate unit serial number is FGT8002803923050

Note: The FortiBridge unit does not have to fail open if the FortiGate unit fails. The
FortiBridge unit can be configured just to send alerts if the FortiGate unit fails.

FortiBridge Version 3.0 Administration Guide
09-30000-0163-20061109

Configuring FortiBridge probes

Configuration and operating procedures

Configure probe settings. Enter:
config probe setting
set action_on_failure alertmail failopen snmp syslog
set dynamic_ip_pattern 2.2.2.*
set fgt_serial FGT8002803923050
end

Enabling probes
Enable probes to control the protocols that the FortiBridge unit uses to confirm
that the FortiGate unit is functioning normally. You can configure probes for ping
(ICMP), HTTP, FTP, POP3, SMTP, and IMAP protocols. For all probes you can
configure the probe interval (the time between consecutive probe packets), and
the probe threshold (the number of probe packets lost before the FortiBridge unit
registers a failure). For HTTP, FTP, POP3, SMTP, and IMAP probes you can also
change the probe port. You would change the probe port for a protocol if the
FortiGate unit uses a non-standard port for that protocol.
The FortiBridge unit simultaneously tests connectivity through the FortiGate unit
for each probe that you have enabled. The first probe that registers a failure
causes all probes to stop and the configured action on failure to occur.
Before you configure probes, the FortiGate unit must be configured to pass the
probe traffic. A single Internal->External firewall policy that allows all traffic also
allows all probe packets. You can also configure individual policies for each
protocol. For example, you could add the policies shown in Figure 14 to the
FortiGate unit.
Figure 14: Sample firewall policies

Policy 1 processes any network traffic. Policy 2 processes all FTP traffic. Policy 2
is above Policy 1 in the policy list, so FTP traffic is matched by policy 2. In the
same way, Policy 3 processes all IMAP traffic.
FTP and IMAP probes would be processed by policies 2 and 3 respectively. All
other probes would be processed by policy 1. This would include pings, SMTP
traffic and so on.
To enable and configure FortiBridge probes
The following steps show examples for configuring ping, HTTP, FTP, POP3,
SMTP, and IMAP probes. For a complete description of FortiBridge probes see
“probe probe_list {ping | http | ftp | pop3 | smtp | imap}” on page 55.

Log into the FortiBridge CLI.

Enable the ping probe using the default ping probe parameters. Enter:
config probe probe_list ping

Configuration and operating procedures

Figure 15: FortiGate Session list showing FortiBridge probes

This session list shows the following:
•

The FortiBridge dynamic probe IP addresses are 2.2.2.213 and 2.2.2.214.

•

IMAP probe packets (port 143) are processed by firewall policy 3.

•

FTP probe packets (port 21) are processed by firewall policy 2.

•

ping probe packets are processed by firewall policy 1.

•

SMTP packets using port 26 are processed by firewall policy 1.

Tuning the failure threshold and probe interval
If you find the FortiBridge unit failing open when the FortiGate unit has not failed
or if the FortiGate unit fails and there is an unacceptably long delay before the
FortiBridge unit fails open, you should adjust the failure threshold and probe
interval.
Failing open when the FortiGate unit has not failed indicates that you should
increase the time the FortiBridge unit waits to fail open. During startup, if the
FortiBridge unit begins sending probe packets before the FortiGate unit has
completed its start up sequence the FortiBridge unit may detect a failure and
switch to bypass mode. Also, if the FortiGate unit is processing high traffic
volumes, a fail open could occur if the FortiGate unit delays FortiBridge probe
packets. You can increase the fail open delay by increasing the failure threshold
and probe interval.
An unacceptable delay before failing open means network traffic can be
interrupted for the time period between when the FortiGate unit fails and the
FortiBridge unit fails open. You can minimize the delay by reducing the failure
threshold and probe interval.

Configuring FortiBridge alerts
Configure FortiBridge alerts so that the alertemail, syslog, and snmp actions
on failure cause the FortiBridge unit to notify system administrators that the
FortiGate unit has failed. Until you configure alert email, syslog, and SNMP alerts,
the FortiBridge cannot notify system administrators of a FortiGate failure.
You can configure the following FortiBridge alerts:

•

FortiBridge alert email

•

FortiBridge syslog

•

FortiBridge SNMP

FortiBridge Version 3.0 Administration Guide

Configuration and operating procedures

Configuring FortiBridge alerts

FortiBridge alert email
If you set the probe action on failure to alertmail, you can configure alert email
so that the FortiBridge unit sends an email message to up to three email
addresses if the FortiBridge unit detects a failure. The alert email informs the
recipient that a FortiGate unit has failed, includes the protocol for which the failure
was detected, and includes the serial number of the FortiGate unit that failed.
Only the first probe to detect a failure triggers the actions on failure. So, even if
multiple probes are configured, when a failure is detected, the FortiBridge unit
sends one alert email.
Figure 16: Sample FortiBridge alert email message

FortiBridge detect FortiGate failure
Time: Tue Feb 1 19:58:46 2005
failed protocol: http
failed FortiGate serial number: FGT8002803923050
To configure alert email
Configuring FortiBridge alert email is similar to configuring FortiGate alert email.
1

Log into the CLI.

Configure alert email. Enter:
config alertemail setting
set server mail.myorg.com
set username user@company.com
set password PassWORD
set mailto1 user@company.com
set mailto1 user2@company.co.uk
set mailto1 user3@company.com
end

FortiBridge syslog
If you set the probe action on failure to syslog, you can configure FortiBridge
syslog so that the FortiBridge unit sends a syslog message to one syslog server if
the FortiBridge unit detects a failure. The message informs the recipient that a
FortiGate unit has failed, includes the protocol for which the failure was detected,
and includes the serial number of the FortiGate unit that failed.
Only the first probe to detect a failure triggers the actions on failure. So, even if
multiple probes are configured, when a failure is detected, the FortiBridge unit
sends one message.

To configure FortiBridge syslog
In most cases you should only need to configure the IP address of the syslog
server to receive FortiBridge syslog messages. See “log syslogd setting” on
page 54 for more FortiBridge syslog options.
1

Log into the CLI.

Configure syslog settings. Enter:
config log syslogd setting
set server 172.20.120.11
end

FortiBridge SNMP
If you set the probe action on failure to snmp, you can configure FortiBridge SNMP
settings so that the FortiBridge unit sends SNMP v1 and v2c compliant traps to
SNMP v1 and v2c compliant SNMP managers if the FortiBridge unit detects a
failure. The traps inform the recipient that a FortiGate unit has failed and include
the protocol for which the failure was detected.
Only the first probe to detect a failure triggers the actions on failure. So, even if
multiple probes are configured, when a failure is detected, the FortiBridge unit
sends one v1 SNMP trap and one v2c SNMP trap.
Configure FortiBridge SNMP by adding and configuring an SNMP community. An
SNMP community is a grouping of equipment for network administration
purposes. You can add up to three SNMP communities. Each community can
have a different configuration for SNMP traps. You can add the IP addresses of up
to 8 SNMP managers to each community.

To add and enable an SNMP community
1

Log into the CLI.

Add the first SNMP community and name it snmp1. Enter:
config system snmp community
edit 1
set name snmp_1
end
The new SNMP community is enabled by default. SNMP v1 and v2 traps are also
enable by default. You can disable traps and change ports. See “system snmp
community” on page 71 for more information.

Add the IP addresses of two SNMP managers that can receive traps. Enter
config system snmp community
edit 1

edit 1
set ip 172.20.120.12
next
edit 2
set ip 192.168.20.102
end
end

Recovering from a FortiGate failure
After the FortiBridge probe detects a FortiGate failure the FortiBridge unit stops
sending probes. To restart probes you can restart the FortiBridge unit, connect to
the FortiBridge CLI and enter the execute switch-mode command, or press
the mode button on the FortiBridge unit front panel.
Normally, an action on failure causes the FortiBridge unit to fail open. When the
FortiBridge unit fails open, it begins operating in Bypass mode. In bypass mode
the INT 1 and EXT 1 interfaces are directly connected and you cannot use Telnet
or SSH to connect to the FortiBridge CLI. Use the following procedure to recover
from bypass mode after a FortiGate failure and resume normal operation.
To resume normal operation from bypass mode
When the FortiBridge unit is operating in bypass mode, you need to do the
following to resume normal operation:
1

Review FortiBridge alerts and check the status of your FortiGate unit and network
components to determine the source of the failure.
A network component or the FortiGate unit could have experienced a general
hardware failure or a specific software failure.

Manually switching between FortiBridge operating modes

Configuration and operating procedures

Make the required changes to fix the problem.
Depending on the cause, this could mean re-connecting and restarting the
FortiGate unit, or diagnosing a problem with the FortiGate unit or other network
component.
If all network and FortiGate unit hardware and software is functioning normally,
you may have to adjust FortiBridge probe settings. See “Tuning the failure
threshold and probe interval” on page 40.

Manually switch the FortiBridge unit from bypass to normal mode.
Connect to the FortiBridge CLI using the console connection and enter the
command:
execute switch-mode
Or press the Mode button on the FortiBridge unit front panel.
Or restart the FortiBridge unit by cycling the power or from the console using he
execute reboot command. The FortiBridge unit always restarts on normal
mode.

Manually switching between FortiBridge operating modes
You can manually switch between FortiBridge operating modes from the
FortiBridge CLI or by pressing the Mode button on the FortiBridge front panel. To
switch operating modes from the CLI enter:
execute switch-mode

Backing up and restoring the FortiBridge configuration
Use the following procedures to backup and restore your FortiBridge
configuration. For both of these procedures, you must have a TFTP server that
you can connect to from any FortiBridge unit interface. The FortiBridge unit must
be operating in normal mode.
To back up the FortiBridge configuration
1

Make sure that the TFTP server is running.

Log into the FortiBridge CLI.

Backup the system configuration to a text file on the TFTP server. Enter:

Keywords and variables

Description

Default

status {disable |
fail_close |
fail_bypass}

The fail_bypass option is only available on the
disable
FBG-1000F.
When the FortiBridge detects an upstream or downstream
network disconnection (whether due to a cut/disconnected
cable, failure of the connected device, or failure of the
FortiBridge unit’s own interface), it will bring down its own
network interface after waiting the amount of time set for
the threshold variable. If the fail close status is set to
fail_close and a switch connected to EXT1 fails, the
FortiBridge would bring down its own INT1. This way, the
device connected to INT1 will be able to determine there is
a problem Similarly, if a device connected to INT1 fails, the
FortiBridge would bring down its own EXT1.
When the problem is corrected, the FortiBridge will enable
its own network interface after waiting the amount of time
set for the threshold variable.
Some early FBG-1000 units will return an Not supported
by this hardware error when this command is invoked. This
is normal as hardware support for fail_close was only
added in later units.
When using a FBG-1000F, some fiber-connected
equipment doesn’t properly detect the status of a
FortiBridge interface brought down by the fail_close
option. To prevent this problem, use fail_bypass
instead. If a network problem is detected with
fail_bypass set, the FortiBridge will switch to bypass
mode. This way, the network devices can detect the
problem directly through the FortiBridge. Note that
fail_bypass causes the FortiBridge to remove itself
from the network when a problem is detected so manual
intervention is required to switch back to normal mode.

threshold

Enter how long, in seconds, the FortiBridge will wait after 3
detecting a network problem before activating the fail close
feature. Except when fail_bypass is set, the FortiBridge
will wait the specified time before deactivating the fail close
feature when the problem is corrected.

SNMP v1 compatible, v2c functionality is disabled. After the community is configured the SNMP
manager is added. The SNMP manager IP address is 192.168.20.34.
config system snmp community
edit 1
set name SNMP_Com1
set trap_v2c_status disable
config hosts
edit 1
set ip 192.168.10.34
end
end
