Multitenancy and VDOMs

This section covers the following topics:

• FortiSwitch ports dedicated to VDOMs
• FortiSwitch VLANs from different VDOMs sharing the same FortiSwitch ports

FortiSwitch ports dedicated to VDOMs

Virtual domains (VDOMs) are a method of dividing a FortiGate unit into two or more virtual units that function as multiple independent units. VDOMs provide separate security domains that allow separate zones, user authentication, security policies, routing, and VPN configurations.

FortiSwitch ports can now be shared between VDOMs.

Starting in FortiOS 6.2.0, the following features are supported on FortiSwitch ports shared between VDOMs:

• POE pre-standard detection (on a per-port basis if the FortiSwitch model supports this feature)
• Learning limit for dynamic MAC addresses on ports, trunks, and VLANs (if the FortiSwitch unit supports this feature)
• QoS egress CoS queue policy (if the FortiSwitch unit supports this feature)
• Port security policy

The following example shows how to share FortiSwitch ports between VDOMs:

1. In the tenant VDOM named bbb, create a VLAN interface using the following CLI commands (not supported in the GUI):

   FG5H0E3917900081 (bbb) #

   config system interface

   edit "bbb-vlan99"

   set vdom "bbb"

   set allowaccess ping

   set device-identification enable

   set role lan

   set snmp-index 58

   set switch-controller-dhcp-snooping enable

   set interface "flink-lag" // this is the FortiLink interface in the root VDOM

   set vlanid 99

   next

   end

   config switch-controller global

   set default-virtual-switch-vlan "bbb-vlan99"

   end

2. Go back to the root VDOM. Pick a switch port to share between VDOMs, port10 in this case.

   FG5H0E3917900081 (vdom) # edit root

   current vf=root:0

   FG5H0E3917900081 (root) # config switch-controller managed-switch

   FG5H0E3917900081 (managed-switch) # edit S548DF4K15000276

   FG5H0E3917900081 (S548DF4K15000276) # config ports

   FG5H0E3917900081 (ports) # edit port10

   FG5H0E3917900081 (port10) # set export-to bbb

   If you want to use the virtual-pool feature instead:

   FG5H0E3917900081 (root) # config switch-controller virtual-port-pool

   edit "bbb-pool"

   set description "bbb-vlan-pool"

   end

   FG5H0E3917900081 (root) # config switch-controller managed-switch

   FG5H0E3917900081 (managed-switch) # edit S548DF4K15000276

   FG5H0E3917900081 (S548DF4K15000276) # config port

   FG5H0E3917900081 (ports) # edit port11

   FG5H0E3917900081 (port11) # set export-to-pool bbb-pool

3. Go back to the bbb VDOM to claim port11 because it is in the virtual pool but not directly exported to the VDOM yet. (The administrator might want to pre-assign some ports in the tenant VDOM and let the tenant VDOM administrator claim them before they are used.)

   FG5H0E3917900081 (bbb) # execute switch-controller virtual-port-pool request S548DF4K15000276 port11

   FG5H0E3917900081 (bbb) # config switch-controller managed-switch // The switch port is now in the bbb VDOM even though there is no FortiLink interface in the bbb VDOM.

   FG5H0E3917900081 (managed-switch) # show

   config switch-controller managed-switch

   edit "S548DF4K15000276"

   set poe-detection-type 1

   set type virtual

   set owner-vdom "root"

   config ports

   edit "port10"

   set poe-capable 1

   set vlan "bbb-vlan99"

   next

   edit "port11"

   set poe-capable 1

   set vlan "bbb-vlan99"

   next

   end

   next

   end

4. Check your configuration on the root VDOM:

   FG5H0E3917900081 (port10) # show

   config ports

   edit "port10"

   set poe-capable 1

   set export-to "bbb"

   next

   end

   FG5H0E3917900081 (port11) # show

   config ports

   edit "port11"

   set poe-capable 1

   set export-to-pool "bbb-pool"

   set export-to "bbb"

   next

   end

5. Check your configuration on the tenant VDOM:

   FG5H0E3917900081 (ports) # show

   config ports

   edit "port10"

   set poe-capable 1

   set vlan "bbb-vlan99"

   next

   edit "port11"

   set poe-capable 1

   set vlan "bbb-vlan99"

   next

   end

You can create your own export tags using the following CLI commands:

config switch-controller switch-interface-tag

edit <tag_name>

end

Use the following CLI command to list the contents of a specific VPP:

execute switch-controller virtual-port-pool show-by-pool <VPP_name>

Use the following CLI command to list all VPPs and their contents:

execute switch-controller virtual-port-pool show

NOTE: Shared ports do not support the following features:

• LLDP
• STP
• BPDU guard
• Root guard
• DHCP snooping
• IGMP snooping
• MCLAG
• Quarantines

NOTE: After you export a switch port to a pool, if you need to export the switch port to a different pool, you need to exit/abort and then re-enter into the FortiSwitch CLI port configuration.

FortiSwitch VLANs from different VDOMs sharing the same FortiSwitch ports

In this scenario, there is no administrative separation, and all FortiSwitch ports and VLANs are created and assigned by the administrator of the VDOM where the FortiSwitch unit is controlled, usually root.

1. From the global level, go to Network > Interfaces and click Create New to create the VLANs and then assign them to their respective VDOMs.
2. In the GUI, go to WiFi & Switch Controller > FortiSwitch Ports.
3. Select a port and click Edit.
4. Assign the VLAN to the FortiSwitch port.

   The assigned VLANs are displayed in the GUI (WiFi & Switch Controller > FortiSwitch Ports) in the root VDOM.

   

NOTE: FortiSwitch units are not visible in non-root VDOMs.
