switchport allowed vlan
This command configures VLAN groups on the selected interface. Use
the no form to restore the default.
Note: Each port can only have one untagged VLAN. If a second VLAN is defined
for a port as untagged, the other VLAN that had untagged status will
automatically be changed to tagged. Setting a VLAN untagged will also
change the native VLAN of the port to this VLAN.

Interface Configuration (Ethernet, Port Channel)
Command Usage
• A port, or a trunk with switchport mode set to hybrid, must be
assigned to a 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.
• The interface can be added to a VLAN as an untagged member
regardless of connected devices to this interface. The default setting is
untagged VLAN 1. Note that each port can only have one untagged
