Configuring The Tpid Value In Vlan Tags - 3Com 4210G Series Configuration Manual

To do...
Create a class and enter
class view
Specify the inner VLAN
ID(s) of matching frames
Exit to system view
Create a traffic behavior
and enter traffic behavior
view
Specify an outer VLAN ID
Exit to system view
Create a QoS policy and
enter QoS policy view
Associate the traffic class
with the traffic behavior
defined earlier
Exit to system view
Enter the
Ethernet port
view of the
customer
network-side
port
Enable basic QinQ
Apply the QoS policy in
the inbound direction
For detailed information about QoS policies, refer to the part talking about QoS in the QoS
Volume.
By configuring different match criteria, you can add outer VLAN tags to packets more flexibly. For
example, you can add an outer VLAN tag to packets with the specified source IP/source MAC,
add different outer VLAN tags to packets of different protocols (matched through ACL), or add
different outer VLAN tags to packets with different priorities.

Configuring the TPID Value in VLAN Tags

You can configure the TPID value in VLAN tags in system view, where the configuration takes effect on
all ports of the device.
