Table 6: VSAs That Apply to Dynamic IP Interfaces (continued)
VSA Description
Egress-Statistics Indicates
whether
statistics are
collected on
output
QoS-Profile-Name Specifies the
name of the
QoS profile
to attach to
the interface
To use the VSAs shown in Table 6 on page 79:
Specify the policy, or one or more QoS VSAs in the desired RADIUS user entries.
Create the ingress or egress policy, or the QoS profile. Policies minimally consist of one
or more policy commands and may include classifier control lists and rate limit profiles.
See the JunosE Policy Management Configuration Guide for more information about
policies and policy routing. See the JunosE Quality of Service Configuration Guide for
information about creating QoS profiles.
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.
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
