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.
