Command Usage
• A port, or a trunk with switchport mode set to hybrid, must be assigned to at least
one VLAN as untagged.
• If a trunk has switchport mode set to trunk (i.e., 1Q 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.
