ONFIGURATION
Selecting the VLAN Operation Mode
The system can be configured to operate in normal mode or one of the
tunneling modes used for passing Layer 2 traffic across a service provider’s
metropolitan area network, including IEEE 802.1Q tunneling (QinQ) or
static VLAN tag swapping (VLAN Swap).
Command Attributes
• Normal – The switch functions in normal operating mode.
This is the default operating mode, and should be placed in this mode
when using standard IEEE 802.1Q VLANs (page 13-2), private VLANs
(page 13-18), or protocol VLANs (page 13-20).
• QinQ – Sets the switch to QinQ mode, and allows the QinQ tunnel port
to be configured. For an explanation of QinQ, see “Configuring IEEE
802.1Q Tunneling” on page 13-24.
• VLAN Swap – Sets the switch to VLAN Swap mode, which swaps
VLAN tags when packets are passed between the service provider and
customer. For an explanation of VLAN swapping, see “Configuring
VLAN Swapping” on page 13-33.
Note: If there are any dot1q-tunnel ports set on the switch, the system
will not be able to exit QinQ mode (see “Configuring IEEE
802.1Q Tunneling” on page 13-24).
