Command Usage
• If switchport mode is set to trunk, then you can only assign an
interface to VLAN groups as a tagged member.
• Frames are always tagged within the switch. The tagged/
untagged parameter used when adding a VLAN to an interface
tells the switch whether to keep or remove the tag from a frame
on egress.
• If none of the intermediate network devices nor the host at the
other end of the connection supports VLANs, the interface
should be added to these VLANs as an untagged member.
Otherwise, it is only necessary to add at most one VLAN as
untagged, and this should correspond to the native VLAN for
the interface.
• If a VLAN on the forbidden list for an interface is manually
added to that interface, the VLAN is automatically removed
from the forbidden list for that interface.
