  • The switch uses the outer VLAN tag of packets to determine where to forward the packets and to learn MAC address entries.
  • Selective QinQ is recommended to be enabled on a hybrid interface and VLAN translation must be enabled using the qinq vlan-translation enable command. Selective QinQ can take effect on the interface only in the inbound direction.
  • If an interface configured with VLAN stacking needs to remove the outer tag from outgoing frames, the interface must join the VLAN specified by stack-vlan in untagged mode. If the outer tag does not need to be removed, the interface must join the VLAN specified by stack-vlan in tagged mode.
  • When selective QinQ is configured on an interface, the interface can add only one outer VLAN tag to a received frame with an inner VLAN tag, and the outer VLAN ID must exist. If the outer VLAN ID does not exist, the services where selective QinQ is configured are unavailable.
  • If only single-tagged packets from a VLAN need to be transparently transmitted, do not specify the VLAN as the inner VLAN for selective QinQ. After selective QinQ is configured on the S3700EI, S3700SI, and S5700EI, the VLAN from which single-tagged packets are transparently transmitted must be mapped to itself using the port vlan-mapping command (for example, port vlan-mapping vlan 20 map-vlan 20).

  • If VLAN stacking is configured, do not configure stack-vlan as the VLAN corresponding to the VLANIF interface.

  • VLAN-based flow mirroring allows the switch to identify only the outer VLAN tag of QinQ packets.
  • The globally configured traffic-limit command that takes effect for all interfaces in the inbound direction is invalid for QinQ packets.
  • The S5720EI, S5720HI, S5730HI, S6720EI, S6720HI, and S6720S-EI support configuration of ND snooping and adding double tags to untagged packets.

  • The S5720EI, S5720HI, S5730HI, S6720EI, S6720HI, and S6720S-EI support configuration of SAVI and adding double tags to untagged packets.

  • If the PW-side routing interface is a Layer 3 interface switched by the undo portswitch command, the AC-side interface cannot be a Layer 3 routing interface or its sub-interface belonging to a Layer 3 interface; otherwise, traffic fails to be forwarded. This rule applies to S5720EI, S6720EI, and S6720S-EI.
