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:
