Access Plane
The Access Plane defines subscriber access and establishes access sessions before user traffic starts. In the web interface, it appears as the task builder's Access Groups tab and is used for IPoE, PPPoE, DHCPv4/DHCPv6, SLAAC, 802.1X, and related access protocols.
Reusable Network Tunnel profiles (Library → VLAN, VXLAN, GRE, IP-IP, and IPsec) are documented separately. They are selected in a Data Plane plugin's parameter group and are not Access Groups access sessions.

Access Groups can be combined with Data Plane plugins. In this case, access sessions are established before user traffic starts, and plugin traffic uses the prepared access infrastructure.
