◆
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.

XAMPLE
The following example shows how to add VLANs 1, 2, 5 and 6 to the
allowed list as tagged VLANs for port 1:
Console(config)#interface ethernet 1/1
Console(config-if)#switchport allowed vlan add 1,2,5,6 tagged
Console(config-if)#
switchport

This command enables ingress filtering for an interface. Use the no form to
restore the default.
