segregate and preserve customer VLAN IDs for traffic crossing the
service provider network.
■
Tunnel Uplink – Configures QinQ tunneling for an uplink port to
another device within the service provider network.

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.
