Triggering Ancp Line Configuration; Adjusting The Data Rate Reported By Ancp For Dsl Lines - Juniper IP SERVICES - CONFIGURATION GUIDE V 11.1.X Configuration Manual

JUNOSe 11.1.x IP Services Configuration Guide

Triggering ANCP Line Configuration

Use the l2c line-configuration command to trigger line configuration to the access
node. Issuing this command sends a GSMP port management message to the access
node. This message enables the B-RAS to configure a service profile name on an
access loop.
NOTE: Before issuing the l2c line-configuration command, a profile must already
be configured locally on the access node.

Adjusting the Data Rate Reported by ANCP for DSL Lines

When a DSLAM calculates the data rate, it ignores additional headers on the DSL
line. When ANCP reports the upstream data rate (L2C Type 4 Sub-type 129) or the
downstream data rate (L2C Type 4 Sub-type 130), it includes the headers in its
calculation and therefore reports a slightly higher value. This discrepancy causes the
QoS shaping rate to be slightly higher than the actual rate.
You can use the adjustment-factor command to set a percentage value ANCP applies
to the data rate to generate a more accurate value that is reported to AAA whenever
AAA requests the data rate from ANCP.
ANCP does not report the calculated data rate to RADIUS or to L2TP.

Triggering ANCP Line Configuration
Use to enable the QoS adaptive mode for ANCP.
QoS adaptive mode enables the system to shape VLAN and ATM VC downstream
rates received from ANCP by dynamically creating QoS parameter instances
associated with the ANCP (L2C) downstream application.
Example
host1(config-l2c)#qos-adaptive-mode
Use the no version to disable QoS adaptive mode for the system.
See qos-adaptive-mode.
Use to trigger a GSMP port management message to the access node. This
message enables the B-RAS to configure a service profile name on an access
loop.
Example
host1#l2c line-configuration interface atm 2/0.11 profile1
There is no no version.
See l2c line-configuration.
