Multiple FortiSwitches in tiers via aggregate interface with MCLAG enabled on all tiers

This example provides a recommended configuration of FortiLink where multi-tier FortiSwitch devices are managed by an A-P mode HA cluster of FortiGates acting as a switch controller via an aggregate interface. The FortiGates provide AA links to two distribution FortiSwitches that are connected to each other by MCLAG. All access FortiSwitch devices have A-A links with two upper tier FortiSwitches, as long as the MCLAG-ICL has been enabled between the upper tiers.

Prerequisites:

  • The FortiGate model supports an aggregate interface. l FortiSwitch units have been upgraded to latest released software version.
  • Layer-3 path/route in the management VDOM is available to Internet so that the FortiSwitch units can synchronize NTP. l For the FortiSwitch D series, the models above 4 just support MCLAG. For the FortiSwitch E series, the models above 2 just support MCLAG.

Change the FortiSwitch management mode to FortiLink:

Enter the following CLI commands on the FortiSwitch:

config system global set switch-mgmt-mode fortilink

end

This operation will cleanup all of the configuration and reboot the system!

Do you want to continue? (y/n)y

Backing up local mode config before entering FortiLink mode….

If the FortiSwitch ports used for the FortiLink connection have auto-discovery-fortilink enabled, executing authorization on FortiGate will trigger the transformation to FortiLink mode automatically.

config switch interface

edit “port1” set auto-discovery-fortilink enable

…… next

end

Set up an A-P mode HA cluster:

See HA active-passive cluster setup on page 212.

Create an aggregate interface and designate it as Fortilink interface on the FortiGate:

Using the CLI:

config system interface edit “aggr1” set vdom “vdom1” set fortilink enable set type aggregate set member “port11” “port12”

set fortilink-split-interface disable

next

end fortilink-split-interface must be disabled for MCLAG to work.

Using the GUI:

  1. Go to WiFi & Switch Controller> FortiLink Interface.
  2. In Interface members, select one or more physical ports that are connected to different distribution FortiSwitches to create an aggregate interface.
  3. Disable FortiLink split interface.
  4. Configure other fields as necessary.
  5. Click OK.

Discover and authorize the FortiSwitch:

Using the CLI:

config switch-controller managed-switch edit “FSWSerialNum” set fsw-wan1-admin enable

…… next

end

Check the CLI output for Connection: Connected to show that FortiLink is up:

execute switch-controller get-conn-status FSWSerialNum

Get managed-switch S248EPTF18001384 connection status:

Admin Status: Authorized

…… Using the GUI:

  1. Go to WiFi & Switch Controller> Managed FortiSwitch.
  2. Click Authorize and wait for a few minutes for the connection to be established.

When FortiLink between the FortiGate and FortiSwitch is established, the Link-up ports change to green and the POE port that is supplying power changes to blue. The dotted line between the FortiGate and FortiSwitch changes to a solid line. The Connection status shows that FortiLink is up.

Enable MCLAG on the ICL link between the distribution FortiSwitch devices:

conf switch trunk edit “4DN4K15000008-0” set mclag-icl enable

next

end

When you enable mclag-icl, MCLAG on the FortiLink interface is enabled automatically and active-active backup links between the distribution FortiSwitches are established.

Extend the security perimeter to the edge of FortiSwitch:

  1. Configure the VLAN arrangement.
    1. On the FortiGate, go to WiFi & Switch Controller> FortiSwitch VLANs.
    2. Configure the VLAN interfaces that are applied on FortiSwitch.

On FortiGate, these switch VLAN interfaces are treated as layer-3 interfaces and are available to be applied by firewall policy and other security controls in FortiOS. This means that security boundary is extended to FortiSwitch.

  1. Configure FortiSwitch ports.
    1. On the FortiGate, go to WiFi & Switch Controller> FortiSwitch Ports.
    2. Select one or more FortiSwitch ports and assign them to the switch VLAN.
    3. You can also select POE/DHCP Snooping, STP, and other parameters for the FortiSwitch ports to show their real-time status such as link status, data statistics, etc.
  2. Configure access authentication.
    1. On the FortiGate, go to WiFi & Switch Controller> FortiSwitch Security Policies.
    2. Configure the 1X security policies.
    3. Select Port-based or MAC-based mode and select Usergroups from the existing VDOM.
    4. Configure other fields as necessary.
    5. Go to WiFi & Switch Controller> FortiSwitch Ports.
    6. Select one or more FortiSwitch ports, click + in the Security Policy column, then make a selection from the pane.

Multiple FortiSwitches in tiers via aggregate interface with redundant link enabled

This example provides a recommended configuration of FortiLink where multi-tier FortiSwitches are managed by an A-P mode HA cluster of FortiGates as switch controller via aggregate interface, where each FortiGate cluster member can provide redundant links to multiple (>=2) distribution FortiSwitches.

Prerequisites:

  • The FortiGate model supports an aggregate interface. l FortiSwitch units have been upgraded to latest released software version.
  • Layer-3 path/route in the management VDOM is available to Internet so that the FortiSwitch units can synchronize NTP.

Change the FortiSwitch management mode to FortiLink:

Enter the following CLI commands on the FortiSwitch:

config system global set switch-mgmt-mode fortilink

end

This operation will cleanup all of the configuration and reboot the system!

Do you want to continue? (y/n)y

Backing up local mode config before entering FortiLink mode….

If the FortiSwitch ports used for the FortiLink connection have auto-discovery-fortilink enabled, executing authorization on FortiGate will trigger the transformation to FortiLink mode automatically.

config switch interface

edit “port1” set auto-discovery-fortilink enable

…… next

end

Set up an A-P mode HA cluster:

See HA active-passive cluster setup on page 212.

Create an aggregate interface and designate it as Fortilink interface on the FortiGate:

Using the CLI:

config system interface edit “aggr1” set vdom “vdom1” set fortilink enable set type aggregate set member “port11” “port12” set fortilink-split-interface enable

next

end

Using the GUI:

  1. Go to WiFi & Switch Controller> FortiLink Interface.
  2. In Interface members, select one or more physical ports that are connected to different distribution FortiSwitches to create an aggregate interface.
  3. Enable FortiLink split interface.
  4. Configure other fields as necessary.
  5. Click OK.

Discover and authorize the FortiSwitch:

Using the CLI:

config switch-controller managed-switch edit “FSWSerialNum” set fsw-wan1-admin enable

…… next

end

Check the CLI output for Connection: Connected to show that FortiLink is up:

execute switch-controller get-conn-status FSWSerialNum

Multiple FortiSwitches managed via hardware/software switch

This example provides a recommended configuration of FortiLink where multiple FortiSwitches are managed by an A-P mode HA cluster of FortiGates as switch controller via hardware or software switch interface. An example of common usage is when you need multiple distribution FortiSwitches but lack supporting aggregate on the FortiGate pairs.

Prerequisites:

  • The FortiGate model supports hardware or software switch interface. l FortiSwitch units have been upgraded to latest released software version.
  • Layer-3 path/route in the management VDOM is available to Internet so that the FortiSwitch units can synchronize NTP.

Change the FortiSwitch management mode to FortiLink:

Enter the following CLI commands on the FortiSwitch:

config system global set switch-mgmt-mode fortilink

end

This operation will cleanup all of the configuration and reboot the system!

Do you want to continue? (y/n)y

Backing up local mode config before entering FortiLink mode….

If the FortiSwitch ports used for the FortiLink connection have auto-discovery-fortilink enabled, executing authorization on FortiGate will trigger the transformation to FortiLink mode automatically.

config switch interface

edit “port1” set auto-discovery-fortilink enable

…… next

end

Set up an A-P mode HA cluster:

See HA active-passive cluster setup on page 212.

Create hardware or software switch interface and designate it as FortiLink interface on the FortiGate:

Create a hardware switch using the CLI:

config system virtual-switch edit “hardswitch1” set physical-switch “sw0” config port edit “port11” next edit “port12” next

end

next

end

Create a software switch using the CLI:

config system switch-interface edit “softswitch1” set vdom “vdom1” set member “port11” “port12”

next

end

Using the GUI:

  1. Go to WiFi & Switch Controller> FortiLink Interface.
  2. In Interface members, select an existing hardware/software switch interface (if there is one) or select one or more physical ports to create a hardware/software switch interface.
  3. Configure other fields as necessary.
  4. Click OK.

Discover and authorize the FortiSwitch:

Using the CLI:

config switch-controller managed-switch edit “FSWSerialNum” set fsw-wan1-admin enable

…… next

end

Check the CLI output for Connection: Connected to show that FortiLink is up:

execute switch-controller get-conn-status FSWSerialNum

Get managed-switch S248EPTF18001384 connection status:

Admin Status: Authorized

…… Using the GUI:

  1. Go to WiFi & Switch Controller> Managed FortiSwitch.
  2. Click Authorize and wait for a few minutes for the connection to be established.

When FortiLink between the FortiGate and FortiSwitch is established, the Link-up ports change to green and the POE port that is supplying power changes to blue. The dotted line between the FortiGate and FortiSwitch changes to a solid line. The Connection status shows that FortiLink is up.

Extend the security perimeter to the edge of FortiSwitch:

  1. Configure the VLAN arrangement.
    1. On the FortiGate, go to WiFi & Switch Controller> FortiSwitch VLANs.
    2. Configure the VLAN interfaces that are applied on FortiSwitch.

On FortiGate, these switch VLAN interfaces are treated as layer-3 interfaces and are available to be applied by firewall policy and other security controls in FortiOS. This means that security boundary is extended to FortiSwitch.

  1. Configure FortiSwitch ports.
    1. On the FortiGate, go to WiFi & Switch Controller> FortiSwitch Ports.
    2. Select one or more FortiSwitch ports and assign them to the switch VLAN.
    3. You can also select POE/DHCP Snooping, STP, and other parameters for the FortiSwitch ports to show their real-time status such as link status, data statistics, etc.
  2. Configure access authentication.
    1. On the FortiGate, go to WiFi & Switch Controller> FortiSwitch Security Policies.
    2. Configure the 1X security policies.
    3. Select Port-based or MAC-based mode and select Usergroups from the existing VDOM.
    4. Configure other fields as necessary.
    5. Go to WiFi & Switch Controller> FortiSwitch Ports.
    6. Select one or more FortiSwitch ports, click + in the Security Policy column, then make a selection from the pane.

Troubleshooting

Bind FortiLink on hardware switch interface

Fortinet recommends binding FortiLink on the hardware switch interface. Since the hardware switch interface can leverage hardware chips to forward traffic, it does not consume CPU capacity, unlike a software switch.

Authorized FortiSwitch always offline

If an authorized FortiSwitch is always offline, go to the FortiGate CLI and use the command below to see all the checkpoints. Inspect each checkpoint to find the cause of the problem. execute switch-controller diagnose-connection S248EPTF18001384

Multiple FortiSwitches in tiers via aggregate interface with MCLAG enabled only on distribution

This example provides a recommended configuration of FortiLink where multi-tier FortiSwitches are managed by a standalone FortiGate as switch controller via aggregate interface, where the FortiGate can provide active-active links to two distribution FortiSwitches connected to each other by MCLAG.

Prerequisites:

  • The FortiGate model supports an aggregate interface. l FortiSwitch units have been upgraded to latest released software version.
  • Layer-3 path/route in the management VDOM is available to Internet so that the FortiSwitch units can synchronize NTP.
  • For the FortiSwitch D series, the models above 4 just support MCLAG. For the FortiSwitch E series, the models above 2 just support MCLAG.

Change the FortiSwitch management mode to FortiLink:

Enter the following CLI commands on the FortiSwitch:

config system global set switch-mgmt-mode fortilink

end

This operation will cleanup all of the configuration and reboot the system!

Do you want to continue? (y/n)y

Backing up local mode config before entering FortiLink mode….

If the FortiSwitch ports used for the FortiLink connection have auto-discovery-fortilink enabled, executing authorization on FortiGate will trigger the transformation to FortiLink mode automatically.

config switch interface

edit “port1” set auto-discovery-fortilink enable ……

next

end

Create an aggregate interface and designate it as Fortilink interface on the FortiGate:

Using the CLI:

config system interface edit “aggr1” set vdom “vdom1” set fortilink enable set type aggregate set member “port11” “port12” set fortilink-split-interface disable

next

end fortilink-split-interface must be disabled for MCLAG to work.

Using the GUI:

  1. Go to WiFi & Switch Controller> FortiLink Interface.
  2. In Interface members, select one or more physical ports that are connected to different distribution FortiSwitches to create an aggregate interface.
  3. Disable FortiLink split interface.
  4. Configure other fields as necessary.
  5. Click OK.

Bind FortiLink on hardware switch interface

Fortinet recommends binding FortiLink on the hardware switch interface. Since the hardware switch interface can leverage hardware chips to forward traffic, it does not consume CPU capacity, unlike a software switch.

Standalone FortiGate as switch controller

In this example, one FortiSwitch is managed by a standalone FortiGate. The FortiGate uses an aggregate interface to operate as a switch controller. This configuration might be used in branch office. It might also be used before increasing the number of connected FortiSwitch units and evolving to a multi-tier structure.

Prerequisites:

  • The FortiGate model supports an aggregate interface. l FortiSwitch units have been upgraded to latest released software version.
  • Layer-3 path/route in the management VDOM is available to Internet so that the FortiSwitch units can synchronize NTP.
