vlan trunk native

Syntax

vlan trunk native <VLAN-ID>

no vlan trunk native [<VLAN-ID>]

Description

Assigns a native VLAN ID to a LAG interface. By default, VLAN ID 1 is assigned as the LAG VLAN ID for all LAG interfaces. VLANs can only be assigned to a nonrouted (layer 2) interface or LAG interface. Only one VLAN ID can be assigned as the native VLAN.

The no form of this command removes a native VLAN from a LAG interface and assigns VLAN ID 1 as its native VLAN.
