Parameters
hex-value: Sets a hexadecimal TPID value in the range of 0x0001 to 0xFFFF, excluding the reserved
EtherType values listed in
Usage guidelines
A service provider-side port uses the SVLAN TPID to replace the TPID in outgoing frames' SVLAN
tags, in addition to matching incoming tagged frames.
Examples
# Set the SVLAN TPID to 0x9100 on GigabitEthernet 1/0/1.

qinq transparent-vlan
Use qinq transparent-vlan to enable transparent transmission for a list of VLANs on a port.
Use undo qinq transparent-vlan to disable transparent transmission for a list of VLANs on a port.
Syntax
qinq transparent-vlan vlan-id-list
undo qinq transparent-vlan { vlan-id-list | all }
Default
Transparent transmission is disabled for all VLANs on a port.

Parameters
vlan-id-list: Specifies a space-separated list of up to 10 VLAN items. Each item specifies a single
VLAN ID or a VLAN ID range in the form of vlan-id1 to vlan-id2. The value range for VLAN IDs is 1 to
4094. The end VLAN ID must be equal to or greater than the start VLAN ID.
all: Specifies all existing VLANs.
Usage guidelines
By default, QinQ tags all incoming frames with the PVID on a port. This command disables QinQ to
tag incoming traffic from a list of VLANs. These VLANs are called transparent VLANs.
To ensure successful transmission for a transparent VLAN, follow these configuration guidelines:
•
Set the link type of the port to trunk or hybrid, and assign the port to its PVID and the transparent
VLAN.
•
Do not configure any other VLAN manipulation actions for the transparent VLAN on the port.
•
Make sure all ports on the traffic path permit the transparent VLAN to pass through.
