Configuring A Dynamic Atm 1483 Subinterface - Juniper JUNOSE SOFTWARE 11.0.X - LINK LAYER CONFIGURATION GUIDE 4-1-2010 Configuration Manual

Chapter 16: Configuring Dynamic Interfaces Using Bulk Configuration
Configuration Method Using Subscriber Management Application
You can use the JUNOSe subscriber management application to configure and manage
IP subscribers associated with a dynamic bridged Ethernet interface column. The
subscriber management application uses an IP service profile to manage and
authenticate IP subscribers with RADIUS. An IP service profile contains user and
password information, and is used in a route map for subscriber management and
to authenticate subscribers with RADIUS.
In this configuration, the IP service profile provides the subscriber's authentication
parameters, and the subscriber management application acts as the authenticating
layer to obtain information from RADIUS for configuration of dynamic IP subscribers.
To assign the IP service profile to the interface profile from which the dynamic bridged
Ethernet interface is created, you use the bridge1483 service-profile command in
Profile Configuration mode.
If stateful SRP switchover is disabled or not running on your router, you can continue
to use the atm atm1483 subscriber command to configure IP subscribers on dynamic
bridged Ethernet interfaces to support RADIUS authentication.
Alternatively, you can use the subscriber management application to create and
configure dynamic IP interfaces regardless of whether stateful SRP switchover is
running on the router. In addition, using subscriber management enables you to take
advantage of several useful features such as the IP inactivity timer.
In the event that an interface profile for a dynamic bridged Ethernet interface includes
the atm atm1483 subscriber command to configure a local subscriber as well as
the bridge1483 service-profile command to reference an IP service profile, the
values specified with the atm atm1483 subscriber command take precedence. The
router ignores the values in the IP service profile in this case.
For details about using the subscriber management application to configure RADIUS
authentication for IP subscribers on dynamic bridged Ethernet interfaces, see
"Authenticating Subscribers on Dynamic Bridged Ethernet over Static ATM Interfaces"
on page 473 and "Configuring Subscriber Management for IP Subscribers on Dynamic
Bridged Ethernet Interfaces" on page 511 in "Configuring Dynamic Interfaces" on
page 465. The information in these sections, which explains how to use subscriber
management to achieve the same functionality as the subscriber command without
adversely affecting stateful SRP switchover, applies equally to the atm atm1483
subscriber command.
For more information about using the subscriber management application, see
JUNOSe Broadband Access Configuration Guide.
