associated 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. This mapping
denotes that all customer frames that do not map to any other SAP, will be mapped into this service.
• untagged—Specifies that only untagged frames are accepted on the UNI ports. This mapping denotes
that only untagged frames will be mapped into this service.
For example, the following command specifies that all untagged frames are accepted on UNI ports
associated with SAP 20:
-> ethernet-service sap 20 cvlan 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:
-> no ethernet-service sap 20 cvlan 500
Note that when the last customer traffic association is deleted from a SAP, the SAP itself is not
automatically deleted. No traffic is accepted or processed by a SAP in this state, but the SAP ID is still
known to the switch.
Consider the following when configuring the type of customer traffic to tunnel:
• If no customer traffic is associated with a VLAN Stacking SAP, then the SAP does not process any
traffic for the service.
• Only one all or untagged designation is allowed for any given SAP; specifying both for the same SAP
is not allowed.
• Only one untagged designation is allowed per UNI port, even if the UNI port is associated with
multiple SAPs.
• Only one all designation is allowed per UNI port, even if the UNI port is associated with multiple
SAPs.
Use the show ethernet-service command to display the type of customer traffic associated with each SAP
configured for the switch
