Default Configuration Reverting

RouterOS Beginner Basics
1

Looking at the default configuration on my hEX (750Gr3) it has an action=revert which will clear out the items added by MikroTik. How is this triggered?

I think an alternative would be to upload my own blank configuration as the default configuration. This topic is just to learn more about this particular function of the MikroTik default configuration.

          #-------------------------------------------------------------------------------
          # Revert configuration.
          # these commands are executed if user requests to remove default configuration
          #-------------------------------------------------------------------------------
          :if ($action = "revert") do={
          # remove wan port protection
           /ip firewall filter remove [find comment~"defconf"]
           /ip firewall nat remove [find comment~"defconf"]
           /tool mac-server remove [find interface!=all]
           /tool mac-server set [find] disabled=no
           /tool mac-server mac-winbox remove [find interface!=all]
           /tool mac-server mac-winbox set [find] disabled=no
           /ip neighbor discovery set [find ] discover=yes
             :local o [/ip dhcp-server network find comment="defconf"]
             :if ([:len $o] != 0) do={ /ip dhcp-server network remove $o }
             :local o [/ip dhcp-server find name="defconf" !disabled]
             :if ([:len $o] != 0) do={ /ip dhcp-server remove $o }
             /ip pool {
               :local o [find name="default-dhcp" ranges=192.168.88.10-192.168.88.254]
               :if ([:len $o] != 0) do={ remove $o }
             }
             :local o [/ip dhcp-client find comment="defconf"]
             :if ([:len $o] != 0) do={ /ip dhcp-client remove $o }
           /ip dns {
             set allow-remote-requests=no
             :local o [static find name=router address=192.168.88.1]
             :if ([:len $o] != 0) do={ static remove $o }
           }
           /ip address {
             :local o [find comment="defconf"]
             :if ([:len $o] != 0) do={ remove $o }
           }
           :foreach iface in=[/interface ethernet find] do={
             /interface ethernet set $iface name=[get $iface default-name]
             /interface ethernet set $iface master-port=none
           }
           /interface bridge port remove [find comment="defconf"]
           /interface bridge remove [find comment="defconf"]
           /interface wireless reset-configuration wlan1
           /interface wireless reset-configuration wlan0
          }
          :log info Defconf_script_finished;

A question shows on first login, but I don’t know if you can repeat it later. But you don’t need to, if you want to get rid of default config, just reset it like this:

/system reset-configuration no-defaults=yes

Thanks Sob!
