The preceding example sets the SVID to 99 in the outer tag for egress
packets exiting port 1 when the packet’s CVID is 2. For a more detailed
example, see the switchport dot1q-tunnel service match cvid command.

Use the Configure Global page to set the switch to QinQ mode before
configuring a tunnel access port or tunnel uplink port (see "Enabling
QinQ Tunneling on the Switch" on page 247 ). Also set the Tag Protocol
Identifier (TPID) value of the tunnel access port if the attached client is
using a nonstandard 2-byte ethertype to identify 802.1Q tagged
frames.
◆
Then use the Configure Interface page to set the access interface on
the edge switch to Access mode, and set the uplink interface on the
switch attached to the service provider network to Uplink mode.

default.)
■
Access – Configures QinQ tunneling for a client access port to
segregate and preserve customer VLAN IDs for traffic crossing the
service provider network.
■
Uplink – Configures QinQ tunneling for an uplink port to another
device within the service provider network.
