IEEE 802.1Q Tunneling

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 on page 390.
Adding an Interface to a QinQ Tunnel
Follow the guidelines in the preceding section to set up a QinQ tunnel on the switch. Then use the
VLAN > Tunnel (Configure Interface) page to set the tunnel mode for any participating interface.
CLI References
• “Configuring IEEE 802.1Q Tunneling” on page 388
Command Usage
• 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 733 ).
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.
Parameters
These parameters are displayed:
• Interface – Displays a list of ports or trunks.
• Port – Port Identifier. (Range: 1-12)
• Trunk – Trunk Identifier. (Range: 1-12)
• Mode – Sets the VLAN membership mode of the port.
• None – The port operates in its normal VLAN mode. (This is the 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.
