Configuring ATM Traffic Profiles
C
ONFIGURING
ATM traffic profiles are preconfigured combinations of traffic descriptors and related
parameters, which define the traffic quality of service (QoS) contract. See
Configuration" on page 20
You assign traffic profiles to both upstream and downstream traffic during PVPC and PVCC
configuration. Therefore, you must configure the desired ATM traffic profiles before
configuring ATM service on a particular port.
The following table summarizes the supported cell transfer rates for each Avidia line and
channel card. Use this table to make sure the peak cell rate and sustainable cell rates you specify
during ATM traffic profile configuration are valid. Remember that, while the OC3 line card
supports up to 353,301 cells per second, the configured transfer rates must be supported from
end-to-end. Therefore the configured transfer rate cannot exceed the rate supported by the
channel card used in the circuit.
Card Type
OC3 line card
DS3 line card
DSX-1 line card
T1 channel card
Cell-based ADSL channel card
Frame-based SDSL channel card
When setting up ATM traffic profiles, you need to specify the peak cell rate in
cells per second. To convert bits per second to cells per second, divide the
number of bits per second by 8, then divide the result by 53.
You configure ATM traffic profiles from the ::traffic=> prompt. From the ::root=>
prompt, type the following command then press
