Configuring VLAN mapping
Overview
VLAN mapping re-marks VLAN tagged traffic with new VLAN IDs. Hewlett Packard Enterprise
provides the following types of VLAN mapping:
• One-to-one VLAN mapping—Replaces one VLAN tag with another.
• Many-to-one VLAN mapping—Replaces multiple VLAN tags with the same VLAN tag.
• One-to-two VLAN mapping—Tags single-tagged packets with an outer VLAN tag.
• Two-to-two VLAN mapping—Replaces the SVLAN ID, CVLAN ID, or both IDs for an incoming
double-tagged frame.
Application scenario of one-to-one and many-to-one VLAN
mapping
Figure 59 shows a typical application scenario of one-to-one and many-to-one VLAN mapping. The
scenario implements broadband Internet access for a community.
