Configuring a Dynamic ATM 1483 Subinterface

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 519 and "Configuring Subscriber Management for IP Subscribers on Dynamic
Bridged Ethernet Interfaces" on page 557 in "Configuring Dynamic Interfaces" on page 511.
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.
To configure a dynamic ATM 1483 subinterface:
(Optional) Configure profiles containing characteristics for the dynamic upper-interface
1.
encapsulation types to be created over the dynamic ATM 1483 subinterface.
These profiles are referenced in the base profile for the dynamic ATM subinterface
as nested profile assignments. For detailed instructions on creating profiles, see
"Configuring a Dynamic Interface from a Profile" on page 559 in "Configuring Dynamic
Interfaces" on page 511.
Create the base profile for the dynamic ATM 1483 subinterface by assigning the profile
2.
a name.
host1(config)#profile atm1483BaseProfile
This command accesses Profile Configuration mode, which enables you to configure
attributes in the base profile.
Define attributes for the ATM 1483 subinterface in the base profile.
3.
a. Apply traffic-shaping parameters to the VC range on the ATM AAL5 interface.
b. Configure the ATM 1483 subinterface for autodetection of the PPP upper-interface
encapsulation type.
