NOTE:
- The S5700SI, S5700EI, ES0D0G24SA00 and ES0D0G24CA00 cards of the S7700, and EH1D2G24SSA0 and EH1D2S24CSA0 cards of the S9700 do not support this configuration.
- When you configure the device to add double tags to untagged packets, run the port link-type hybrid command to change the link type of the interface to hybrid if the following message is displayed:
[HUAWEI-GigabitEthernet0/0/1] port vlan-stacking untagged stack-vlan 10 stack-inner-vlan 5 Error: The port is not a Trunk or Hybrid port. - When you configure the fixed device to add double tags to untagged packets, run the qinq vlan-translation enable command to enable VLAN translation if the following message is displayed:
[HUAWEI-GigabitEthernet0/0/1] port vlan-stacking untagged stack-vlan 10 stack-inner-vlan 5 Error: Please configure qinq vlan-translation enable on this port first. - When you configure the device to add double tags to untagged packets, run the undo port hybrid pvid vlan command to restore the PVID of the interface to be 1 if the following message is displayed:
[HUAWEI-GigabitEthernet0/0/1] port vlan-stacking untagged stack-vlan 10 stack-inner-vlan 5 Error: This port has been configured with default VLAN or PVID, please undo it first.
