• 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
“Configuring a UNI Profile” on page 6-24. Each time a profile is assigned to a UNI, the existing profile
is overwritten with the new one.
Use the show ethernet-service uni command to display a list of UNI ports and the profile association for
each port.
Configuring the Type of Customer Traffic to Tunnel
The ethernet-service sap cvlan 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.
For example, the following command specifies that all untagged frames and frames tagged with CVLAN
ID 500 is accepted on UNI ports associated with SAP 20:
-> ethernet-service sap 20 cvlan 500 untagged
Use the no form of the ethernet-service sap cvlan command to delete an association between customer
traffic and a VLAN Stacking SAP. For example, the following command deletes the association between
CVLAN 500 and SAP 20:
-> ethernet-service sap 20 no cvlan 500
Note that when the last customer traffic association is deleted from a SAP, the SAP itself is not automati-
cally deleted. No traffic is accepted or processed by a SAP in this state, but the SAP ID is still known to
the switch.
