The port can be set to a port number such as port1, port2, port3, or port4. Different FortiManager models have different numbers of ports. If the interface is stopped it does not accept or send packets.

If you stop a physical interface, VLAN interfaces associated with it also stop. Enter the interface IPv4 address and netmask. The IPv4 address cannot be on the same subnet as any other interface. Enter the types of management access permitted on this interface.

Separate multiple selected types with spaces. Enter the types of service access permitted on this interface. If you want to add or remove an option from the list, retype the list as required. This example shows how to set the FortiManager port1 interface IPv4 address and network mask to Example This example shows how to set the FortiManager port1 interface IPv4 address and network mask to Enter the speed and duplexing the network port uses: full : M full-duplex half : M half-duplex 10full : 10M full-duplex 10half : 10M half-duplex auto : Automatically negotiate the fastest common speed default.

Enter an alias for the interface. Variables for config ipv6 subcommand :. Allow management access to the interface.It is not complete nor very detailled, but provides the basic commands for troubleshooting network related issues that are not resolvable via the GUI.


I am not focused on too many memory, process, kernel, etc. These must only be used if there are really specific problems. I am more focused on the general troubleshooting stuff. With Fortinet you have the choice confusion between show get diagnose execute.

Not that easy to remember. Likewise the sys system keyword.

Be careful with it, because this command is persistent. Set it to default after usage! Now with the -f option. In order to copy the configuration via SCP from a backup server you must first enable the SCP protocol for the admin:. Even better, you should enable the following feature which saves a backup of your configuration after each logout automatically:.

Use the first three to enable debugging and start the process, while the last one disables the debugging again:. Which is basically ping and traceroute. Unluckily it is shitty difficult to use those commands since you need a couple of subcommands to source pings from a different interface, and so on.

Manually test a failover by decreasing the priority of the current master since highest priority wins :. Start a sync at a secondary device to from?

I would like to decide which config to push to the other device. The first one shows all monitored users with details concerning their LDAP groups :. If you need further debugging messages you can enable it for the Fortigate non-blocking auth daemon and the FSSO daemon:. Sniff packets like tcpdump does.

Only if the built-in packet capture feature in the GUI does not meet your requirements. This can be used for investigating connection problems between two hosts. There are no details of the firewall policy decisions. Use the debug flow next paragraph for analysis about firewall policies, etc.

Examples: Thanks to the comment from Ulrich for the IPv6 example. Kudos to Joachim Schwierzeck. If you want to see the FortiGate details about a connectionuse this kind of debug. To reset a certain VPN connection, use this Credit :. To change the IP address of the mgmt interface or any other via the CLI, these commands can be used:. Just the links here: Resetting a lost Admin password and How to reset a FortiGate with the default factory settings. Nice Job — good summary of most of the commands you need or routinely use.

John K. Hi ihsan, I am not aware of a global history of commands.

As far as I know you can only move through your own commands in that current CLI session arrow up key. With the following CLI command you can see how many lines are stored in the history buffer: get gui console status. On a normal hardware interface, it can be done with this CLI commands:.Im fairly new with Fortigate devices and this is not an issue or anything.

You can set DHCP reservations. I am not sure if there is a command to list the free ones for you, but thats how I'd approach it. Make an Excel sheet with the pool, exclude the ones that are reserved, and the ones that are static, and the ones that are given a lease, the rest must be free I'd like to see a list of unused IP addresses.

This topic has been locked by an administrator and is no longer open for commenting. Read these nextIf you use one of the auto-discovery FortiSwitch ports, you can establish the FortiLink connection single port or LAG with no configuration steps on the FortiSwitch and with a few simple configuration steps on the FortiGate unit.

Configure FortiLink on any physical port on the FortiGate unit and authorize the FortiSwitch unit as a managed switch. You can configure FortiLink on a logical interface: link-aggregation group LAGhardware switch, or software switch.

Hardware switch is supported on some FortiGate models. Ensure that you configure autodiscovery on the FortiSwitch ports unless it is auto-discovery by default. NOTE: If the members of the aggregate interface connect to more than one FortiSwitch, you must enable fortilink-split-interface.

This feature allows FortiSwitch islands FSIs to operate in FortiLink mode over a layer-3 network, even though they are not directly connected to the switch-controller FortiGate unit. FSIs contain one or more FortiSwitch units.

Summary of the procedure Configure FortiLink on a physical port or configure FortiLink on a logical interface. Configure NTP. Authorize the managed FortiSwitch unit. Configure DHCP.

In the following steps, port 1 is configured as the FortiLink port. Configure FortiLink on a logical interface You can configure FortiLink on a logical interface: link-aggregation group LAGhardware switch, or software switch. If required, remove the FortiLink ports from the lan interface: config system virtual-switch edit lan config port delete port4 delete port5 end end end Create a trunk with the two ports that you connected to the switch: config system interface edit flink1 enter a name, 11 characters maximum set ip Authorize the FortiSwitch unit as a managed switch.

Use the following command to enable or disable multiple FortiLink interfaces. The following limitations apply to FSIs operating in FortiLink mode over a layer-3 network: All FortiSwitch units using this feature must be included in the FortiGate preconfigured switch table. The FortiSwitch unit needs a functioning layer-3 routing configuration to reach the FortiGate unit or any featureconfigured destination, such as syslog or All switch ports must remain in standalone mode.

Do not connect a FortiSwitch unit to a layer-3 network and a layer-2 network on the same segment. If the network has a wide geographic distribution, some features, such as software downloads, might operate slowly. To configure a FortiSwitch unit to operate in a layer-3 network: Reset the FortiSwitch to factory default settings with the execute factoryreset Manually set the FortiSwitch unit to FortiLink mode: config system global set switch-mgmt-mode fortilink end Configure the discovery setting for the FortiSwitch unit.

You can either use DHCP discovery or static discovery. The default dhcp-option-code is Mike Posts. The plethora of vendors that resell hardware but have zero engineering knowledge resulting in the wrong hardware or configuration being deployed is a major pet peeve of Michael's. This site was started in an effort to spread information while providing the option of quality consulting services at a much lower price than Fortinet Professional Services.

Leave a Reply Cancel reply.Very helpful, thank you! Even their own employees joke about how things move around and disappear all the time, and this is a good example of one.

Having the instructions above though, configuring option 66 was really simple, so much appreciated. Very good example. You Might show the same example but doing it in the menu of fortigate and not through the console CLI mode?

I forti use os 4 and want to move to the current v5, for me? I don't think this opion 66 config would work.

Thanks for pointing this out. It's not very helpful to read instructional articles that tell you how to do configure things incorrectly. Option code If you have FortiOS 5.

We'll go through the steps to configure a DHCP server from scratch and configure the most commonly used options as well as a few custom ones. Now that we've got the two hexadecimal values we can configure the DHCP custom options as follows:. Now we get to test it out! Labels: 5. Unknown 17 January at Matt 28 May at Alejandro 30 November at ToshiE 6 August at B 3 November at Unknown 8 October at A DHCP server provides an address, from a defined address range, to a client on the network that requests it.

An interface can't provide both a server and a relay for connections of the same type regular or IPsec. However, you can configure a regular DHCP server on an interface only if the interface is a physical interface with a static IP address.

If an interface is connected to multiple networks through routers, you can add a DHCP server for each network.

The routers must be configured for DHCP relay. Edit the interface, and select DHCP in the addressing mode. By default, the FortiGate unit assigns an address range based on the address of the interface for the complete scope of the address. For example, if the interface address is Select the range and select Edit to adjust the range or select Create New to add a different range.

You can enable or disable whether the DHCP relay agent option is added. This option is disabled, by default. Use the following CLI command:. You can use DHCPv6 prefix delegation to assign a network address prefix, and automate the configuration and provisioning of the public routable addresses for the network. You can configure a range for DHCPv6 server prefix delegation.

You can add a prefix range starting and ending prefixes and a prefix length. The prefix length determines the length of the prefix that the FortiGate sends downstream. This feature is used to "hint" to upstream DCHPv6 servers a desired prefix length for their subnet to be assigned in response to its request. Also included in the new feature, are preferred times for the life and valid life of the DHCP lease.

On low-end FortiGate units, a DHCP server is configured on the internal interface, by default, with the following values:. These settings are appropriate for the default internal interface IP address of Just a little bit zoom in a dhcp traffic, too see how it really works in the background. Okay, okay that was not me, that was my colleague but anyway I was the techlead.

Now this is a Fortigate dhcp client and this is just a quick demonstation how easy to debug that application. Lets see what do we see from that in the fortigate debugs. Configure an interface with dhcp and the debug for dhcpc. In the fortigate documentations the timestamp is not mentioned enough where they wrote about debugging. We should use it all the time when we use the debug. You are commenting using your WordPress. You are commenting using your Google account.
