得知 unset ip

會變成這樣是因為我想switch mode 改 interface mode但一直碰到
entry used by table system.dhcp.server:id '1'
entry used by child table srcintf:name 'internal' of table firewall.policy:policyid '1'
因此查網路上教學(以下)
test80C # diagnose sys checkused system.interface.name internal
entry used by table system.dhcp.server:id '1'
entry used by child table srcintf:name 'internal' of table firewall.policy:policyid '1'

查到後就先把它刪除吧
test80C # config firewall policy

test80C (policy) # delete 1

test80C (policy) # end

test80C # config system dhcp server

test80C (server) # delete 1

test80C (server) # end

在重下指令就可以收工了 (做到這邊 下面指令 就無法使用 但我已經看到 可以改成 interface mode，就改了)

test80C (global) # set internal-switch-mode interface

test80C (global) # end
Changing switch mode will reboot the system!
Do you want to continue? (y/n)

test80C #

The system is going down NOW !!

Please stand by while rebooting the system.

目前連不上 fortinet 因為沒IP，有點卡關 請大大解說我該怎辦~。
