Configuration procedure
1) Configuring Switch A
# Create the CVLANs and the SVLANs.
<SwitchA> system-view
[SwitchA] vlan 2 to 3
[SwitchA] vlan 101 to 102
[SwitchA] vlan 201 to 202
[SwitchA] vlan 301 to 302
# Configure uplink policies p1 and p2 to enable one SVLAN to transmit one service for one customer.
[SwitchA] traffic classifier c1
