This command configures the PVID (i.e., default VLAN ID) for a port. Use the no
form to restore the default.
Syntax
switchport native vlan vlan-id

vlan-id - Default VLAN ID for a port. (Range: 1-4093, no leading zeroes)
Default Setting
VLAN 1
Command Mode
Interface Configuration (Ethernet, Port Channel)
Command Usage
• If an interface is not a member of VLAN 1 and you assign its PVID to this VLAN,
the interface will automatically be added to VLAN 1 as an untagged member.
For all other VLANs, an interface must first be configured as an untagged
member before you can assign its PVID to that group.
• If acceptable frame types is set to all or switchport mode is set to hybrid, the
PVID will be inserted into all untagged frames entering the ingress port.
Example
The following example shows how to set the PVID for port 1 to VLAN 3:
switchport allowed vlan
This command configures VLAN groups on the selected interface. Use the no form
to restore the default.
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.
