Receive the packet if
the VLAN ID is the

Use the
port hybrid
vlan command to
configure whether the
port keeps or strips
the tags when
sending packets of a
VLAN (including
default VLAN).
Note:

III. VLAN check
Table 1-1 shows how a port handles traffic by default where VLAN check is enabled.
However, in some cases, on a selective-QinQ-enabled port for example, VLAN check is
