Configuring VLAN Stacking Services
Configuring a VLAN Stacking Ethernet service requires several steps. These steps are outlined here and
further described throughout this section. For a brief tutorial on configuring a VLAN Stacking service, see
“Quick Steps for Configuring VLAN Stacking” on page 35-8.
1 Create an SVLAN. An SVLAN is associated to a VLAN Stacking service to carry customer or
provider traffic. See “Configuring SVLANs” on page 35-11.
2 Create a VLAN Stacking service. A service name is associated with an SVLAN to identify the
customer traffic that the SVLAN will carry through the provider network. See “Configuring a VLAN
Stacking Service” on page 35-12.
3 Configure Network Network Interface (NNI) ports. An NNI port is associated with an SVLAN and
carries the encapsulated SVLAN traffic through the provider network. See “Configuring VLAN Stacking
Network Ports” on page 35-13.
4 Configure a VLAN Stacking service access point (SAP). A SAP binds UNI ports, the type of
customer traffic, and traffic engineering parameter attributes to the VLAN Stacking service. Each SAP is
associated to one service name, but a single service can have multiple SAPs to which it is associated. See
“Configuring a VLAN Stacking Service Access Point” on page 35-15.
5 Configure User Network Interface (UNI) ports. One or more UNI ports are associated with a SAP to
identify to the service which ports will receive customer traffic that the service will process for tunneling
through the provider network. When a UNI port is associated with a SAP, the SAP parameter attributes
are applied to traffic received on the UNI port. See “Configuring VLAN Stacking User Ports” on
page 35-16.
6 Associate CVLAN traffic with a SAP. This step specifies the type of traffic customer traffic that is
allowed on UNI ports and then tunneled through the SVLAN. The type of customer traffic is associated
with a SAP and applies to all UNI ports associated with the same SAP. See “Configuring the Type of
Customer Traffic to Tunnel” on page 35-16.
7 Define SAP profile attributes. A SAP profile contains traffic engineering attributes for specifying
bandwidth sharing, rate limiting, CVLAN translation or double-tagging, and priority bit mapping. A
default profile is automatically associated with a SAP at the time the SAP is created. As a result, it is only
necessary to configure a SAP profile if the default attribute values are not sufficient. See “Configuring a
Service Access Point Profile” on page 35-18.
8 Define UNI profile attributes. A default UNI profile is automatically assigned to a UNI port at the
time a port is configured as a VLAN Stacking UNI. This profile determines how control frames received
on the port are processed. It is only necessary to configure a UNI profile if the default attribute values are
not sufficient. See “Configuring a UNI Profile” on page 35-19.
