switchport trunk native vlan
The switchport trunk native vlan interface configuration command defines the port as a member
of the specified VLAN, and the VLAN ID as the "port default VLAN ID (PVID)". To configure the
default VLAN ID, use the no form of this command.
Syntax
switchport trunk native vlan vlan-id
no switchport trunk native vlan
•
vlan-id—Valid VLAN ID of the active VLAN.
Default Configuration
VLAN ID=1
Command Mode
Interface Configuration (Ethernet, port-channel) mode
User Guidelines
This command has the following consequences: incoming untagged frames are assigned to
this VLAN and outgoing traffic in this VLAN on this port is sent untagged (despite the
normal situation where traffic sent from a trunk-mode port is all tagged).
The command adds the port as a member in the VLAN. If the port is already a member in the
VLAN (not as a native), it should be first removed from the VLAN.
Example
The following example g8, in trunk mode, is configured to use VLAN number 123 as the "native"
VLAN.
Console (config)# interface ethernet g8
Console (config-if)# switchport trunk native vlan 123
switchport general allowed vlan
The switchport general allowed vlan interface configuration command adds or removes VLANs
from a general port.
