Configuring a VLAN Stacking Service Access Point
The ethernet-service sap command is used to configure a VLAN Stacking service access point (SAP). A
SAP is assigned an ID number at the time it is configured. This ID number is then associated with the
following VLAN Stacking components:
• User Network Interface (UNI) ports. See “Configuring VLAN Stacking User Ports” on page 35-16.
• Customer VLANs (CVLANs). See “Configuring the Type of Customer Traffic to Tunnel” on
page 35-16.
• SAP profile. Each SAP is associated with a single profile. This profile contains attributes that are used
to define traffic engineering parameters applied to traffic ingressing on UNI ports that are associated
with the SAP. See “Configuring a Service Access Point Profile” on page 35-18.
The above components are all configured separately using different VLAN Stacking commands. The
ethernet-service sap command is for creating a SAP ID and associating the ID with a VLAN Stacking
service. For example, the following command creates SAP 20 and associates it with Video-Service:
-> ethernet-service sap 20 service-name Video-Service
To delete a VLAN Stacking SAP from the switch configuration, use the no form of the ethernet-service
sap command. For example, the following command deletes SAP 20:
-> no ethernet-service sap 20
Note that when the SAP is deleted, all UNI port, CVLAN, and profile associations are automatically
dropped. It is not necessary to remove these items before deleting the SAP.
A VLAN Stacking SAP basically identifies the location where customer traffic enters the provider
network edge, the type of customer traffic to service, parameters to apply to the traffic, and the service that
will process the traffic for tunneling through the provider network.
Consider the following when configuring a VLAN Stacking SAP:
• A SAP is assigned to only one service, but a service can have multiple SAPs. So, a single service can
process and tunnel traffic for multiple UNI ports and customers.
• Associating multiple UNI ports to one SAP is allowed.
• A default SAP profile is associated with the SAP at the time the SAP is created. This profile contains
the following default attribute values:
The above default attribute values are applied to customer traffic associated with the SAP. Only one
profile is assigned to each SAP; however, it is possible to use the same profile for multiple SAPs.
• To use different profile attribute values, create a new profile and associate it with the SAP. See
“Configuring a Service Access Point Profile” on page 35-18. Each time a profile is assigned to a SAP,
the existing profile is overwritten with the new one.
