Configure the site1_mclag1 switch

Follow these steps on the site1_mclag1 FortiSwitch unit in the MCLAG peer group:

1. Enable FortiLink mode.

   config system global

   set switch-mgmt-mode fortilink

   end

2. Set the switch-controller discovery type to DHCP.

   config switch-controller global

   set ac-discovery-type dhcp

   end

3. Enable FortiLink over layer 3 on the switch interface connected to the WAN router and enable LACP on the newly formed __FoRtILnk0L3__ trunk, which is automatically created by the system.

   config switch interface

   edit port8

   set fortilink-l3-mode enable

   end

   config switch trunk

   edit "__FoRtILnk0L3__"

   set mode lacp-active

   set members "port8"

   next

   end

   config switch interface

   edit "__FoRtILnk0L3__"

   set native-vlan 4094

   set allowed-vlans 1

   set dhcp-snooping trusted

   set igmp-snooping-flood-reports enable

   set igmp-snooping-flood-traffice enable

   set snmp-index 12

   next

   end
