IEEE 802.1QINQ COMMANDS
QinQ, also known as VLAN stacking, is a powerful, yet simple and cost-effective solution that allows Service Providers to
offer IP-based Services, including Metro-Ethernet in scalable implementations. QinQ can also be used to provide multiple
virtual connections and access to multiple services available over the Metro (ISPs, ASPs, storage services, etc.)
The IEEE 802.1QinQ commands in the Command Line Interface (CLI) are listed (along with the appropriate parameters)
in the following table.
Command Parameters
enable qinq
disable qinq
show qinq
config qinq ports
[<portlist> | all] {role [nni | uni] | missdrop [enable | disable] | [outer_ tpid |
tpid]<hex 0x1 - 0xffff> | use_inner_priority [enable | disable]}(1)
show qinq ports
{<portlist>}
delete vlan_translation ports
[<portlist> | all ] { cvid <vidlist>}
show vlan_translation {[ports <portlist>}
create vlan_translation ports
[<portlist> | all ] cvid <vidlist> [add | replace] svid <vlanid 1
-4094> {priority
<value 0-7>}
Each command is listed, in detail, in the following sections.
enable qinq
Purpose Used to enable QinQ.
Syntax
enable qinq
Description When QinQ is enabled, all network port roles will be NNI port and outer TPID will be set to
0x88A8; All existed static VLAN will run as S-VLAN; All dynamic learned L2 address will be
cleared; All dynamic registered VLAN entries will be cleared, and GVRP will be disabled.
If need to run GVRP on the switch, administrator should enable GVRP manually. In QinQ
mode, GVRP protocol will employ reserve address 01-80-C2-00-00-0D.
The default setting of QinQ is disabled.
Parameters None.
Restrictions Only Administrator and Operator-level users can issue this command.
Example usage:
