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.
Syntax
switchport allowed vlan {add vlan-list [tagged | untagged] |
remove vlan-list}
no switchport allowed 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: 1-4093).
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 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.
