SP-VID per CPE Port
This configuration applicable in any deployment, encapsulates all customers' frames (tagged
and untagged, without filtering of CE-VID) using an additional SE-VID tag. This
configuration also allows multiple SE-VIDs per CPE (one per port), supporting multiple
customers per CPE. In addition, allows intra-switching between CPEs, using switching
between HSL ports (belonging to the same SE-VID) on CO NE. Management traffic in this
configuration can be either VLAN-tagged or VLAN-untagged, as desired. In-band
management traffic beyond the CPE is unsupported in this case.
