To delete a UNI port association with a VLAN Stacking SAP, use the no form of the ethernet-service sap 
uni command. For example, the following command deletes the association between UNI 1/1 and SAP 
20:

-> ethernet-service sap 20 no uni 1/1

Note that when the last SAP association for the port is deleted, the port automatically reverts back to a 
conventional switch port and is no longer VLAN Stacking capable.

Consider the following when configuring VLAN Stacking UNI ports:

• All customer traffic received on the UNI port is dropped until customer VLANs (CVLAN) are associ-

ated with the port. See 

• If the SAP ID specified with this command is associated with an IPMVLAN, the SAP profile must 

specify CVLAN translation. In addition, multicast traffic is not associated with the IPMVLAN until the 
UNI port is associated with the IPMVLAN as a receiver port. For more information, see the “Configur-
ing IP Multicast VLANs” chapter in this guide.

• A default UNI profile is assigned to the port at the time the port is configured. This profile defines how 

control frames received on the UNI ports are processed. By default, GVRP and Spanning Tree frames 
are tunneled. All other protocol control frames are dropped.

• To use different profile attribute values, create a new profile and associate it with the UNI port. See 

. Each time a profile is assigned to a UNI, the existing 

profile is overwritten with the new one.

Use the 

 command to display a list of UNI ports and the profile association for 

each port.

 command is used to associate customer traffic with a VLAN Stacking 

service access point (SAP). This identifies the type of customer traffic received on the SAP UNI ports that 
the service will process and tunnel through the SVLAN configured for the service. For example, the 
following command specifies that traffic tagged with customer VLAN (CVLAN) 500 is allowed on UNI 
ports associated with SAP 20:

-> ethernet-service sap 20 cvlan 500

In this example, customer frames tagged with VLAN ID 500 that are received on SAP 20 UNI ports are 
processed by the service to which SAP 20 is associated. This includes applying profile attributes associ-
ated with SAP 20 to the qualifying customer frames. If no other customer traffic is specified for SAP 20, 
all other frames received on SAP 20 UNI ports are dropped.

In addition to specifying one or more CVLANs, it is also possible to specify the following parameters 
when using the ethernet-service sap cvlan command:

• all—Specifies that all untagged and tagged frames are accepted on the UNI ports. If this parameter is 

combined with a CVLAN ID and bandwidth sharing and rate limiting are enabled for the SAP profile, 
then frames tagged with the CVLAN ID are given a higher bandwidth priority than all other frames 
received on the port.

• untagged—Specifies that only untagged frames are accepted on the UNI ports. If this parameter is 

combined with a CVLAN ID, then all untagged frames plus frames tagged with the CVLAN ID are 
accepted on the UNI ports.
