Configuring Subscriber Access
To configure subscriber access:
- Configure the client access protocol.
- Configure DHCP local server.
- Configure DHCP relay.
- Configure PPP.
See the “Configuring Logical Interface Properties” and “Configuring Point-to-Point Protocol over Ethernet” chapters of the Junos OS Network Interfaces Library for Routing Devices.
- Configure subscriber authentication, accounting, and addressing.
- Configure RADIUS:
- Specify the RADIUS servers.
See Specifying RADIUS Authentication and Accounting Servers for Subscriber Access.
- Specify any optional server attributes.
See Configuring RADIUS Server Options for Subscriber Access.
- (Optional) Configure the CoA feature for the RADIUS dynamic-request server to change or deactivate the service after login.
- Configure subscriber accounting (RADIUS accounting).
- Specify the RADIUS servers.
- Configure addressing:
- Configure RADIUS:
- Create and manage dynamic profiles for access and service.
- Configure a basic dynamic profile.
- Configure a dynamic profile for access.
- Configure a dynamic profile for services.
See Configuring a Dynamic Profile for Various Levels of Services.
- Configure a default subscriber service.
- Configure the static subscriber interfaces to be referenced
in the dynamic profile.
See Configuring a Subscriber Interface with a Static VLAN Interface.
- Specify the interface-name and unit variables that the
router uses to dynamically associate to a subscriber’s incoming
interface.
See Associating Dynamic Profiles with Statically Created Interfaces.
- Add, modify, or delete dynamic profile values to manage subscriber access and services.
The router dynamically activates or modifies the subscriber service using the RADIUS configuration.
- When the subscriber logs in, the router dynamically activates the service.
- If RADIUS CoA has been configured, the router can dynamically
modify the service for a subscriber.
See RADIUS-Initiated Change of Authorization (CoA) Overview.
Figure 1 shows the configuration sequence you perform for DHCP-based subscriber access. It also shows the dynamic configuration performed by the router.
