VLAN mapping configuration

VLAN mapping overview

VLAN mapping re-marks VLAN tagged traffic with new VLAN IDs. HP provides the following types of
VLAN mapping:
• One-to-one VLAN mapping—Replaces one VLAN tag with another. You can use one-to-one VLAN
mapping to sub-classify traffic from a particular VLAN for granular QoS control.
Many-to-one VLAN mapping—Replaces multiple VLAN tags with the same VLAN tag. You can use
•
many-to-one VLAN mapping to aggregate traffic from different VLANs to regulate the aggregate
traffic as a whole. Many-to-one VLAN mapping is usually used together with one-to-one VLAN
mapping.
Two-to-two VLAN mapping—Replaces the outer and inner VLAN IDs of double tagged traffic with
•
a new pair of VLAN IDs. You can use two-to-two VLAN mapping to enable two remote sites in
different VLANs to communicate at Layer 2 across two service provider networks that use different
VLAN assignment schemes.
Application scenario of one-to-one and many-to-one VLAN
mapping
Figure 63 shows a typical application scenario in which each home gateway uses different VLANs to
transmit the PC, VoD, and VoIP services.
