10.3.4 Weight Parameters

NOTE: Queue 3, Queue 2 and Queue 1 require a Weight parameter range between 0

and 1000. If you enter an invalid weight parameter, INVALID INPUT will appear

proportional to how much bandwidth that queue will receive. The weight value can be of any range
between 0-1000. Type the appropriate number to change the queue weight; 6 for Queue 3, 12 for Queue 2
or 18 for Queue 1. Type in the new setting. Press

Enter to confirm setting.

10.3.5 Early Detect Drop Profiles

Early Detect is a congestion avoidance mechanism that allows you to drop packets based on a specific
profile. The drop can be selectively applied to packets with a specific PCP value or a priority. Doing so
allows you to drop packets before a specific queue is full.

Every Queue has two drop profiles associated to it. They use can configure those drop profile and
associate to a specific class of service. The customer has the ability to enable or disable each ED Drop
Profile independently. Type the appropriate number for the schedule scheme you wish to modify; 7 or 8 for
Queue 3, 13 or 14 for Queue 2, and 19 or 20 for Queue 1. Use the

Space Bar to select Enabled or

Disabled. Press

Enter to confirm setting.
