configure qinq ports
Purpose
Used to configure Q-in-Q port.
Syntax config qinq ports [<portlist> | all] {role [uni | nni] | missdrop [enable | disable] |
outer_tpid <hex 0x1-0xffff>| use_inner_priority [enable | disable] | add_inner_tag [<hex
0x1-0xffff> | disable]}(1)
Description
This command is used to configure the Q-in-Q VLAN mode for ports, include:
port role in double tag VLAN mode, enable/disable SP-VLAN assignment miss drop, port
outer TPID, use inner priority, and enable/disable add inner tag.
If missdrop is enabled, the packet that does not match any VLAN translation rule on the UNI
port will be dropped. If disabled, then the packet will be assigned based on the default VLAN
classification rule. If the port is NNI, this attribute will not take effect.
This setting will not be effective when Q-in-Q mode is disabled.
Parameters
portlist − A range of ports to be configured.
role − Port role in Q-in-Q mode, it can be either UNI port or NNI port.
UNI – User-to-Network Interface specifies that communication between the specified
user and a specified network will occur.
NNI – Network-to-Network Interface speficies that communication between two
specified networks will occur.
missdrop − enable/disable C-VLAN based SP-VLAN assignment miss drop.
outer_tpid – Allows the interoperation with devices on a public network by specifying ports.
use_inner_priority − Specifies whether to use the priority in the C-VLAN tag as the priority in
the SP-VLAN tag.
add_inner_tag - Specifies whether to add inner tag for ingress untagged packets. If set, the
inner tag will be added for the ingress untagged packets and thus the packets egress to the
NNI port will be double tagged. If disable, only s-tag will be added for ingress untagged
packets.
Restrictions
Only Administrator and Operator and Power-User-level users can issue this command. You
must be in the Q-in-Q mode.
Example usage
To configure port 1-4 as NNI port, set outer TPID to 0x88a8:
DES-3528:admin# config qinq ports 1-4 role nni outer_tpid 0x88a8
Command: config qinq ports 1-4 role nni outer_tpid 0x88a8
Success.
DES-3528:admin#
show qinq ports
Purpose
Used to show port’s Q-in-Q mode information.
Syntax show qinq ports <portlist>
Description
This command is used to show the Q-in-Q configuration for a port, including:
port role in Q-in-Q mode, enable/disable to drop the SP-VLAN assignment miss packet, port
outer TPID, use inner priority, and enable/disable add inner tag.
Parameters
portlist − Specifies a range of ports to be displayed.
If no parameter specified, system will display all ports information.
Restrictions
None.
Example usage
To show Q-in-Q port settings:
DES-3528:admin#show qinq ports 1-2
Command: show qinq ports 1-2
