Qinq Transparent-Vlan - H3C S5120-EI Series Command Reference Manual

Use the undo qinq ethernet-type command to restore the TPID value in VLAN tags to the system default.
By default, the TPID value is 0x8100.
Configuration made in system view takes effect on all ports.
•
• The TPID value configured on the S5120-EI series switches applies to both the CVLAN tags and the
SVLAN tags.
Examples
# Set the TPID value to 0x8200 globally.

qinq transparent-vlan

Syntax
qinq transparent-vlan vlan-list
undo qinq transparent-vlan { all | vlan-list }
View
Layer 2 Ethernet interface view, Layer 2 aggregate interface view, port group view
Default level
2: System level
Parameters
vlan-list: Specifies one or multiple existing VLANs in the format of vlan-list = { vlan-id [ to
vlan-id ] }&<1- 1 0>. You can provide up to 10 VLAN ID lists, by each of which you can specify an
individual VLAN ID with the vlan-id argument, or a VLAN ID range in the format of vlan-id to vlan-id,
where the second VLAN ID must be greater than the first VLAN ID. The vlan-id argument ranges from 1
to 4094.
all: Sepcfies all VLANs.
Description
Use the qinq transparent-vlan command to configure VLAN transparent transmission on one or multiple
ports, so the port or ports can transparently transmit frames from the specified VLANs.
Use the undo qinq transparent-vlan command to remove the configuration.
By default, VLAN transparent transmission is not configured on ports.
Configured in Ethernet interface view, this command takes effect on the current port only.
Configured in port group view, this command takes effect on all ports in the port group.
Configured in Layer 2 aggregate interface view, this command takes effect on the Layer 2 aggregate
interface and the member ports in its aggregation group. You can configure this command on a Layer 2
aggregate interface and its member ports separately. Configured on an aggregation member port, this
command takes effect immediately. For more information about link aggregation, see the Layer 2—LAN
Switching Configuration Guide.
Examples
# Enable basic QinQ on GigabitEthernet 1/0/1, and configure GigabitEthernet 1/0/1 to transparently
transmit frames from VLAN 2, VLAN 3, and VLAN 50 through VLAN 100.
