To tag frames leaving an interface in Layer 2 mode, you must assign that interface to a port-based VLAN
to tag it with that VLAN ID. To tag interfaces, use these commands in the following sequence:

Except for hybrid ports, only a tagged interface can be a member of multiple VLANs. Hybrid ports can be
assigned to two VLANs if the port is untagged in one VLAN and tagged in all others.
When you remove a tagged interface from a VLAN (using the
tagged only if it is a tagged interface in another VLAN. If the tagged interface is removed from the only
VLAN to which it belongs, the interface is placed in the Default VLAN as an untagged interface.

Enable an interface to include the IEEE 802.1Q tag
header.
Use the show vlan command to
view the interface's status.
