Huawei – combo link fail when you upgrade to V200R009*

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
 description LAB Link
 combo-port auto
 ip address 10.98.65.2 255.255.255.252
