Step
4.
Assign the port to the
CVLANs.
5.
Configure the port to allow
packets from the SVLAN to
pass through untagged.
6.
Configure a one-to-two VLAN
mapping.

Displaying and maintaining VLAN mapping

VLAN mapping configuration examples

One-to-one VLAN mapping configuration example

Network requirements
As shown in
•
Each household subscribes to PC, VoD, and VoIP services, and obtains the IP address through
DHCP.
•
On the home gateways, VLANs 1, 2, and 3 are assigned to PC, VoD, and VoIP traffic,
respectively.
To isolate traffic of the same service type from different households, configure one-to-one VLAN
mappings on the wiring-closet switches. This feature assigns one VLAN to each type of traffic from
each household.

Command
•
For the trunk port:
port trunk permit vlan
vlan-id-list
•
For the hybrid port:
port hybrid vlan vlan-id-list
{ tagged | untagged }
•
For the trunk port:
a. Configure the SVLAN as the
PVID of the trunk port:
port trunk pvid vlan vlan-id
b. Assign the trunk port to the
SVLAN:
port trunk permit vlan
{ vlan-id-list | all }
•
For the hybrid port:
port hybrid vlan vlan-id-list
untagged
vlan mapping nest { range
vlan-range-list | single vlan-id-list }
nested-vlan vlan-id
Command
display vlan mapping [ interface interface-type interface-number ]

Remarks
N/A
N/A
By default, no VLAN mapping
is configured on an interface.
Only one SVLAN tag can be
added to packets from the
same CVLAN. To add
different SVLAN tags to
different CVLAN packets, set
the port link type to hybrid and
repeat this command.
