The subscriber access feature is limited to MX Series Ethernet Services Routers and the interfaces you can use when configuring dynamic profiles.
Even though many statements appear in the CLI for various other platforms, Juniper Networks supports subscriber access DHCP configuration on MX Series routers only. In addition, PPPoE configuration is currently supported on M120 and M320 routers only.

To identify subscribers statically, you can reference a static VLAN interface in a dynamic profile. To identify subscribers dynamically, you create variables for IP demux interfaces that are dynamically created when subscribers log in.
The subscriber access feature supports the following device types:
Certain subscriber management features require the use of specific dense port concentrators (DPCs) on the MX series router. For a list of the MX series DPCs and the features they support, see the MX Series Ethernet Services Routers DPC Guide.
