Considerations and limitations
No support for per VLAN protocol downstream tagging mode
In SVLAN cross-connect tunnel mode:
•
•
When using CVLAN translation, or when the same queue is used for multiple pbits, the highest pbit
value in the queue in the downstream direction will be selected to stomp the pbit in the packet
Simultaneous configuration of a CVLAN port and an S-Tunnel on the same UNI will only be supported
if these services are provisioned with non-overlapping pbits
The same VLAN port must be used when employing both protocol-based VLAN for PPPoE and
IPoE-based VLANs
When the VLAN is translated, the pbit value must be modified and the highest pbit value is mapped
to that GEM port
When more than one Ethernet port is in VLAN translation mode, or set to flexible mode with IGMP
channels created, the USERSIDE VLAN IDs of those services are different. All downstream multicast
packets will be tagged on the UNI port with VLAN ID of 4094
Maximum use of multicast on 1 Ethernet port at a time
For C forwarder and S+C CC forwarder, if the VLAN port uses regenerated profiles or regenerated
pbits, then the downstream traffic can only flow with the derived pbits

Table 1-2 Package A ONT considerations and limitations
use non-overlapping pbits since the use of the same pbits on two or more VLAN ports results in
a mismatch alarm
downstream frames sent with a single tag normally sent out on the user-side as untagged, will
instead be sent as priority tagged
