Configuring The Inner-To-Outer Tag Priority Mapping Feature; Selective Qinq Configuration Example; Processing Private Network Packets By Their Types - 3Com WX3000 Series Operation Manual

You are recommended not to configure both the DHCP snooping and selective Q-in-Q function on the
device, which may result in the DHCP snooping to function abnormally.

Configuring the Inner-to-Outer Tag Priority Mapping Feature

Configuration Procedure
Follow these steps to configure the inner-to-outer tag priority mapping feature:
To do...
Enter system view
Enter Ethernet port view
Enable the inner-to-outer tag
priority mapping feature and

Selective QinQ Configuration Example

Processing Private Network Packets by Their Types

Network requirements
As shown in Figure
GigabitEthernet 1/0/3 of Switch A provides public network access for PC users and IP phone users.
PC users belong to VLAN 100 through VLAN 108, and IP phone users belong to VLAN 200 through
VLAN 230. GigabitEthernet 1/0/5 of Switch A is connected to the public network. The peer end of
Switch A is Switch B.
GigabitEthernet 1/0/11 of Switch B is connected to the public network. GigabitEthernet 1/0/12 and
GigabitEthernet 1/0/13 of Switch B provide network access for PC servers belonging to VLAN 100
through VLAN 108 and voice gateways (for IP phone users) belonging to VLAN 200 through VLAN
230 respectively.
The public network permits packets of VLAN 1000 and VLAN 1200. Apply QoS policies for these
packets to reserve bandwidth for packets of VLAN 1200. That is, packets of VLAN 1200 have
higher transmission priority over packets of VLAN 1000.
Employ the selective QinQ feature on Switch A and Switch B to differentiate traffic of PC users from
that of IP phone users, for the purpose of using QoS policies to guarantee higher priority for voice
traffic.
To reduce broadcast packets in the network, enable the inter-VLAN MAC address replicating
feature for selective QinQ.
