Shaping Mode; Monitoring Qos Configurations For L2Tp - Juniper JUNOSE 11.1.X - QUALITY OF SERVICE CONFIGURATION GUIDE 3-21-2010 Configuration Manual

JUNOSe 11.1.x Quality of Service Configuration Guide
For those logical interfaces with a rate controlled by QoS, QoS reports this configured
rate as the transmit connect speed for that interface. For the logical interfaces that
do not have a QoS-configured rate, QoS reports the speed of the underlying physical
port as the transmit connect speed.
For each logical interface, QoS determines the rate of the interface using either the
shaping rate or the shared-shaping rate, if one is configured. The numeric value of
the shaping rate or shared-shaping rate is determined as the result of a
provider-specified arithmetic expression in a scheduler profile. This expression can
either be a constant value, such as 1,000,000, or an expression using QoS parameters,
with values supplied by RADIUS or statically in non-volatile storage (NVS).
If the QoS profile or the QoS parameters are configured in RADIUS, these values are
used in computing the rate at the time of login. The system can subsequently modify
the value of parameters through change of authorization (CoA), Service Manager, or
L2C. Modifications are not reflected in the rate QoS reports because they might take
place after the LAC has sent the message that contains AVP 24.

Shaping Mode

When the QoS shaping mode is set to cell for an interface, QoS reports the ATM rate.
In cell mode, user-specified rates account for cell headers and trailers, which are
ATM native rates; therefore, QoS does not convert the rates for AVP 24.
