Configuring VLAN Stacking Services

Configuring VLAN Stacking

OmniSwitch AOS Release 6 Network Configuration Guide

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 

. Each time a profile is assigned to a SAP, 

the existing profile is overwritten with the new one.

Use the 

 command to display the SAPs configured for the switch. Use the 

 command to display a list of VLAN Stacking services and the SAPs associated with each 

service.

 command is used to configure a switch port or a link aggregate as a VLAN 

Stacking User Network Interface (UNI) and associate the UNI with a VLAN Stacking service access point 
(SAP). For example, the following command configures port 1/1 as an UNI port and associates 1/1 with 
SAP 20:

-> ethernet-service sap 20 uni 1/1

A UNI port is a customer-facing port on which traffic enters the VLAN Stacking service. When the port is 
associated with a service access point, the port is automatically defined as a UNI port and the default 
VLAN for the port is changed to a VLAN that is reserved for the VLAN Stacking application.
