if you plan to move from V200R007* to V200R009* pay attention to your combo interfaces:
interface GigabitEthernet0/0/8
description LAB Link
combo-port copper
ip address 10.98.65.2 255.255.255.252
during the firmware upgrade the combo-port configuration disappears causing the interface down! So do not upgrade from remote site!!!
Before the upgrade or after if you have missed the device… set combo-port to AUTO.
interface GigabitEthernet0/0/8
