Subscriber Access Support Considerations
The subscriber access feature is limited to MX Series Ethernet Services Routers and the interfaces you can use when configuring dynamic profiles.
Platform Support
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 MX Series routers, M120 routers, and M320 routers.
Interface Support
You can use dynamic profiles to configure statically created interfaces and also to create and configure interfaces dynamically. Subscriber interfaces support IPv4 and IPv6 addressing.
To identify subscribers statically, you can reference a static VLAN interface in a dynamic profile. To identify subscribers dynamically, you create variables for demux interfaces that are dynamically created when subscribers log in.
The subscriber access feature supports the following device types:
- GE -- Gigabit Ethernet
- XE -- 10–Gigabit Ethernet
- AE -- Aggregated Ethernet
DPC Support
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 3D Universal Edge Routers Line Card Guide.
