# Configure Ethernet 1/0/3 as a hybrid port and configure VLAN 5 as its default VLAN.
Configure Ethernet 1/0/3 to remove VLAN tags when forwarding packets of VLAN 5,
VLAN 1000, and VLAN 1200.

# Configure global tag mapping rules for selective QinQ to insert VLAN 1000 tag as the
outer VLAN tag in packets with the tags of VLAN 100 through VLAN 108 as the inner

After the above configuration, packets of VLAN 100 through VLAN 108 (that is, packets
of PC users) are tagged with the tag of VLAN 1000 as the outer VLAN tag when they
are forwarded to the public network by Switch A; and packets of VLAN 200 through
VLAN 230 (that is, packets of IP phone users) are tagged with the tag of VLAN 1200 as
the outer VLAN tag when they are forwarded to the public network.
z Configure Switch B.
# Create VLAN 1000, VLAN 1200, VLAN 12 (the default VLAN of Ethernet1/0/12) and
VLAN 13 (the default VLAN of Ethernet1/0/13) on Switch B.
