H3C-S5500-52C-EI 灵活qinq配置问题

设备型号：H3C-S5500-52C-EI 

需要实现功能：

interface GigabitEthernet1/0/20      

port hybrid untagged vlan 101

port vlan-stacking untagged stack-vlan 101 stack-inner-vlan 501

以上为华为交换机的灵活qinq配置，带2层Tag Vlan标签

需要将同样的灵活qinq功能移植到S5500中

按以下配置后，GE2/0/1 和 GE2/0/28端口各接一台PC，2台PC之间ping不通（undo port hybrid vlan 1后就不通了），请教是哪里配置错误？

S5500的配置如下：

[H3C]interface GigabitEthernet2/0/1

[H3C-GigabitEthernet2/0/1]display this

#

interface GigabitEthernet2/0/1

 port link-mode bridge

 port link-type hybrid

 undo port hybrid vlan 1

 port hybrid vlan 101 untagged

 qinq enable

 qinq vid 101

  raw-vlan-id inbound 501
