35 Configuring VLAN
Stacking
VLAN Stacking provides a mechanism to tunnel multiple customer VLANs (CVLAN) through a service
provider network using one or more service provider VLANs (SVLAN) by way of 802.1Q double-tagging
or VLAN Translation. This feature enables service providers to offer their customers Transparent LAN
Services (TLS). This service is multipoint in nature so as to support multiple customer sites or networks
distributed over the edges of a service provider network.
This implementation of VLAN Stacking offers the following functionality:
• Ingress bandwidth sharing across User Network Interface (UNI) ports.
• Ingress bandwidth rate limiting on a per UNI port, per CVLAN, or CVLAN per UNI port basis.
• CVLAN (inner) tag 802.1p-bit mapping to SVLAN (outer) tag 802.1p bit.
• CVLAN (inner) tag DSCP mapping to SVLAN (outer) tag 802.1p bit.
• Profiles for saving and applying traffic engineering parameter values.
In This Chapter
This chapter describes the basic components of VLAN Stacking and how to define a service-based or port-
based configuration through the Command Line Interface (CLI). CLI commands are used in the
configuration examples; for more details about the syntax of commands, see the OmniSwitch AOS Release
8 CLI Reference Guide.
