H3C S3100 Series Command Manual page 975

By default, one-to-one VLAN mapping is disabled.
With a port-level one-to-one VLAN mapping rule configured for a port, one-to-one VLAN mapping
is enabled on the port at the same time. In this case, the vlan-mapping enable command cannot
be used to enable one-to-one VLAN mapping again.
One-to-one VLAN mapping and the protocol-based VLAN function are mutually exclusive on the
same port.
One-to-one VLAN mapping is mutually exclusive with many-to-one VLAN mapping. With
many-to-one VLAN mapping enabled on any port, you cannot enable one-to-one VLAN mapping
on any other port.
One-to-one VLAN mapping is mutually exclusive with VLAN ID marking. For more information
about VLAN ID marking, see QoS-QoS Profile Configuration.
