VLAN Commands
4-173
4
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.

•
add
vlan-list
- List of VLAN identifiers to add.
•
remove
vlan-list
- List of VLAN identifiers to remove.
•
vlan-list
- Separate nonconsecutive VLAN identifiers with a comma and no
spaces; use a hyphen to designate a range of IDs. Do not enter leading
zeros. (Range: 1-4094).
Default Setting
All ports are assigned to VLAN 1 by default.
The default frame type is untagged.
Command Mode
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 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.
• 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.
