Traffic Shaping For Ppp Over Atm Interfaces; Table 7: Traffic-Shaping Vsas That Apply To Dynamic Ip Interfaces - Juniper JUNOSE SOFTWARE 11.0.X - BROADBAND ACCESS CONFIGURATION GUIDE 4-1-2010 Configuration Manual

When a dynamic interface is created according to a profile, the router checks with
RADIUS to determine whether an input or output policy or a QoS profile must be
applied to the interface. The VSA, if present, provides the name, enabling policy or
QoS profile lookup. If found, the policy or QoS profile is applied to the dynamic
interface.
The router also determines whether the creation profile specifies any policies to be
applied to the interface. Policies specified by the RADIUS VSA supersede any specified
by the profile, as described in the following example:
The RADIUS user entry includes an Ingress-Policy-Name VSA that specifies the policy
input5. The profile specifies two policies, input7 and output1. In this case, the
RADIUS-specified input policy (input5) and the profile-specified output policy (output1)
are applied to the dynamic interface.
For information about assigning policies via profiles, see the JUNOSe Policy
Management Configuration Guide. Only attributes assigned by RADIUS appear in
RADIUS Acct-Start messages. RADIUS attributes specified by a profile for dynamic
interfaces do not appear in RADIUS Acct-Start messages because the profile is not
active when the Acct-Start message is generated. These attributes appear in RADIUS
Acct-Stop messages for a profile that is active when the session is terminated.

Traffic Shaping for PPP over ATM Interfaces

The router supports the configuration of traffic shaping parameters for PPP over ATM
(PPPoA) via domain-based profiles and RADIUS. In connection with this feature,
Table 7 on page 83 describes VSAs that apply to dynamic IP interfaces and are
supported on a per-user basis from RADIUS.
