It can co-exist with 0.* SAP on an access-uplink or access port. A default QinQ SAP accepts only
tagged packets. Untagged packets or priority tagged packets are not accepted on Default QinQ
SAPs.
When an EPIPE service With default QinQ SAPs on the ring ports is used for transit traffic in a
ring deployment, no protection mechanism (example: STP or G.8032) is supported for Default
QinQ SAPs. The upstream or head-end node on which the service originates must ensure the
correct path on the ring is selected using either G.8032 or STP. When a VPLS service with default
QinQ SAPs on the ring ports is used for transit traffic in a ring deployment, users can use either
G8032 or M-VPLS with xSTP for ring protection. When using G8032, the state of the default
QinQ SAPs in the VPLS service can be managed using a separate G8032 control instance.
NOTE: G8032 control instance cannot use Default QinQ SAPs.
Default QinQ SAP is available for use only in an EPIPE and a VPLS service created with svc-
saptype parameter set to "null-star". Default QinQ SAP can be configured along with other SAPs
allowed in the same service (that is, service with svc-sap-type parameter set to "null-star").
Following features are available for use with Default QinQ SAPs configured in EPIPE and VPLS
service (unless explicitly specified, below listed features are applicable for both EPIPE and VPLS
service):

7210 SAS M Services Guide
MAC learning and aging is available for use in a VPLS service
Per SAP MAC limit is available for use in a VPLS service
Mac-move detection and Mac-pinning is available for use in a VPLS service
Discard-unknown and discard-unknown-source is available for use in a VPLS service
ETH-CFM and Y.1731 is not available for use
STP (and all its different flavors) cannot be enabled in the service with Default QinQ
SAPs
MVPLS with xSTP can be used for loop prevention. The Default QinQ SAPs inherit the
state from the associated MVPLS instance.
G.8032 control instance cannot be configured in a service with Default QinQ SAP
G8032 can be used for loop prevention in ring deployments, where the Default QinQ
SAPs are configured on the ring ports in a VPLS service. A separate G8032 control
instances needs to be configured for use on the ring ports and the service with Default
QinQ ports needs to be associated with this G8032 control instance
IGMP snooping is not available for use
L2PT and BPDU translation is not available for use
IP interface in a VPLS service is not supported in a service using this SAP
