3.12.3 ATM traffic shaping

The objectives of ATM traffic management are to deliver quality-of-service
(QoS) guarantees for the multimedia applications and provide overall
optimization of network resources. Currently, GRT-101/GRT-401 supports two
kinds of ATM QoS service: constant bit rate (CBR) and unspecified bit rate
(UBR). The CBR connection involves a static amount of bandwidth allocated
for those applications of video, voice, and circuit emulation. The bandwidth is
characterized by the peak cell rate (PCR) in the configuration. The UBR
connection allows you to define the PCR too. However, it has the lowest
priority and is with no QoS guarantees. The range of the PCR is from 64 to
2400Kbps.
To set the class of the ATM traffic shaping for WAN 3 to CBR with PCR of
512Kbps, enter:
admin# setup wan 3 qos class CBR
admin# setup wan 3 qos pcr 512
To review the new configuration you have changed for WAN 3, type:
admin# setup wan 3 list
