Feature Description

UPF supports segmenting the enterprise traffic using Virtual LAN (VLAN). VLANs enable a single physical LAN segment to be further segmented into smaller virtual networks so that the groups of ports are isolated from one another, as if they were on physically different segments. In VLAN segmentation, the UEs belonging to different classes are assigned to different VLANs for traffic isolation.

VLAN Segmentation can be achieved using two methods:

  1. Next Hop Forwarding

  2. Virtual Routing and Forwarding

In the VLAN segmentation using next hop forwarding, the IP pool is mapped with the VLAN tags. This mapping takes place at the SMF. The IP pool is associated with the next hop forwarding address on the N6 interface, which is reachable through the VLAN associated with the IP pool as configured on the Control Center.

Note

This feature is supported on both 1-Rack Unit and 3-Rack Unit architectures and can support up to 16 VLANs on the N6 interface.
