Shaper
Shaper is used to control traffic flows in order to optimize or guarantee performance
and improve latency by limiting the maximum bandwidth of certain flows to maintain
fairness and to assure SLA.
You must set the Committed Information Rate to a value between 1-1000 Mbps.
Table
7-2
provides an example of Shaper.

Refer to
Figure 7-6 WFQ/Shaper Setup
for configuration using the Web EMS.
7.1.3.3
Egress Queues
There are eight egress queues, one queue per CoS. Eight queues on the interfaces (Eth0,
Eth1, and Eth2) are served by four queues on the radio (RF).
WFQ and Shaper can only be configured for queues 1 through 5.
