Native VLAN
Each physical port may have a native VLAN assigned. All untagged frames are assigned to the LAN specified
in the PVID parameter. When received packet is tagged with the PVID, that packet is treated as if it was
untagged. Therefore, the configuration associated with the native VLAN must be placed on the main interface.
The native VLAN allows the coexistence of VLAN-aware bridge or stations with VLAN-unaware bridges or
stations.
VLAN Sub-interfaces on Ethernet Bundles
An Ethernet bundle is a group of one or more Ethernet ports that are aggregated together and treated as a
single link. Multiple VLAN sub-interfaces can be added to a single Ethernet bundle.
The procedure for creating VLAN sub-interfaces on an Ethernet bundle is exactly the same as the procedure
for creating VLAN sub-interfaces on a physical Ethernet interface. To create a VLAN subinterface on an
Ethernet bundle, see the
How to Configure 802.1Q VLAN Interfaces, on page 113
section later in this module.
How to Configure 802.1Q VLAN Interfaces
This section contains the following procedures:
Configuring 802.1Q VLAN Subinterfaces
This task explains how to configure 802.1Q VLAN sub-interfaces. To remove these sub-interfaces, see the
Removing an 802.1Q VLAN Subinterface, on page 118
section of this module.
