Configuration prerequisites
All service terminals of home users are using DHCP for obtaining an IP address. For how to get an
IP address through DHCP, refer to DHCP Configuration in the IP Services Volume.
The CVLAN-to-SVLAN mappings have been planned.
Configuration procedure

Enter system view
Enable DHCP snooping
Enable ARP
detection on the
CVLANs and the
SVLAN for the
VLAN mapping

CVLANs to the same SVLAN
Enter the interface view of the
downlink port
Set the link type of the downlink port to
trunk
Configure the downlink port to permit
the specified CVLANs and SVLANs to
