Monitoring QoS Configurations for L2TP

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.
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.
