32.14 switchport trunk native vlan

If an untagged packet arrives on a trunk port, it is directed to the port's native
VLAN. Use the switchport trunk native vlan Interface Configuration (Ethernet,
port-channel) mode command to define the native VLAN for a trunk interface. Use
the no form of this command to restore the default native VLAN.
Syntax
switchport trunk native vlan
no switchport trunk native vlan
Parameters
vlan-id—Specifies the native VLAN ID.
Default Configuration
The default VLAN is the native VLAN.
Command Mode
Interface Configuration (Ethernet, port-channel) mode
User Guidelines
The command adds the port as a member of the VLAN. If the port is already a
member of the VLAN (not a native), it must first be removed from the VLAN.
If the interface is a forbidden member of the specified VLAN, it does not become a
member of the VLAN, but the command does not fail. Instead, an error message is
switchport access
vlan-id
vlan.
