Usage Guidelines
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 (For example, 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 or 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.
Example
The following is sample output from the switchport allowed vlan command.
This example shows how to add VLANs 1, 2, 5 and 6 to the allowed list as tagged VLANs for port 1:
