[hjezzapaula]

Description	This article describes how to configure automation stitch to disable and re-enable the WAN interface when the link-monitor changes status from alive to dead.
Scope	FortiGate.
Solution	config system link-monitor     edit "wan-link-monitor"         set srcintf "port1"      <----- WAN Interface.         set server "8.8.8.8"         set gateway-ip X.X.X.X <----- WAN Gateway.     next Configure the automation trigger. In the example below, the automation stitch will only trigger once the link-monitor changes status from 'Alive' to 'Dead'. It will not trigger the automation-stitch if the initial state of the link-monitor is  'Dead'. CLI: config system automation-trigger     edit "WAN-Link Down"         set event-type event-log         set logid 22922             config fields                 edit 1                     set name "name"                     set value "wan-link-monitor"   <----- Link-Monitor Name.                 next                 edit 2                     set name "msg"                     set value "Link Monitor changed state from alive to dead, protocol: ping."                 next             end     next end GUI: Configure the automation Action CLI script to disable and enable the WAN port. CLI: config system automation-action     edit "Disable WAN port"         set action-type cli-script         set script "config system interface             edit port1                 set status down         end"         set accprofile "super_admin"     next     edit "Enable WAN port"         set action-type cli-script         set script "config system interface             edit port1                 set status up         end"         set accprofile "super_admin"     next end GUI: Configure the Automation-Stitch: CLI: config system automation-stitch     edit "Bounce_WAN"         set trigger "WAN-Link Down"             config actions                 edit 1                     set action "Disable WAN port"                     set required enable                 next                 edit 2                     set action "Enable WAN port"                     set delay 10                     set required enable                 next             end     next end GUI: Set the delay to 10s. Once the automation stitch is triggered, it will disable the interface and enable it back after 10 seconds.
