Interface

To add an interface to a QinQ tunnel:

1. Click VLAN, Tunnel.

2. Select Configure Interface from the Step list.

3. Set the mode for any tunnel access port to Access and the tunnel uplink port to Uplink.

4. Click Apply.

Protocol VLANs

The network devices required to support multiple protocols cannot be easily grouped into a
common VLAN. This may require non-standard devices to pass traffic between different VLANs in
order to encompass all the devices participating in a specific protocol. This kind of configuration
deprives users of the basic benefits of VLANs, including security and easy accessibility.

To avoid these problems, you can configure this switch with protocol-based VLANs that divide the
physical network into logical VLAN groups for each required protocol. When a frame is received at a
port, its VLAN membership can then be determined based on the protocol type being used by the
inbound packets.

Command Usage

To configure protocol-based VLANs, follow these steps:

1. First configure VLAN groups for the protocols you want to use (

page 378

). Although not

mandatory, we suggest configuring a separate VLAN for each major protocol running on
your network. Do not add port members at this time.

2. Create a protocol group for each of the protocols you want to assign to a VLAN using the

Configure Protocol (Add) page.

3. Then map the protocol for each interface to the appropriate VLAN using the Configure

Interface (Add) page.

When MAC-based, IP subnet-based, and protocol-based VLANs are supported concurrently,
priority is applied in this sequence, and then port-based VLANs last.
