Configuration restrictions and guidelines

When you configure VLAN mapping, follow these restrictions and guidelines:
When you configure one-to-two VLAN mapping on a QinQ-enabled port, the switch operates as
•
follows:
If a packet matches the one-to-two VLAN mapping, the switch tags the packet with the SVLAN
that is specified in the VLAN mapping.
If a packet does not match the one-to-two VLAN mapping, the switch tags the packet with the
PVID.
When you configure one-to-one or many-to-one VLAN mapping on a QinQ-enabled port, the
•
switch operates as follows:
If a packet matches the one-to-one or many-to-one VLAN mapping, the switch replaces the
CVLAN tag with the SVLAN tag specified in the VLAN mapping.
If a packet does not match the one-to-one or many-to-one VLAN mapping, the switch tags the
packet with the PVID.
For more information about QinQ, see
• To add or replace VLAN tags for packets, you can configure both VLAN mapping and a QoS
policy. However, the QoS policy takes effect if a configuration conflict occurs. For information about
QoS policies, see ACL and QoS Configuration Guide.
VLAN mapping is mutually exclusive with EVB. Do not enable both features on a port. For more
•
information, see EVB Configuration Guide.
