10.3.3 Scheduling Scheme
The 9145E supports two scheduling modes: Strict Priority (SP) and Weigh Fair Queuing (WFQ).
All queues can be set to service packets using one of the scheduling mode mentioned above to
the exception to the LLQ. The LLQ is always set by default to SP. Type the appropriate number
for the schedule scheme you wish to modify; 5 for Queue 3, 11 for Queue 2 or 17 for Queue 1.
Use the Space Bar to cycle between Strict Priority and Weighted Fair. Press Enter to confirm
setting.
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 at the bottom of the screen.
If WFQ is set as the scheduling method, a weigh need to be assigned to each queue. The queue
is 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.
10.4 Early Detect Drop Profile Configuration
You can enable and disable each drop profile, as well as set the MIN, MAX, and MID values for
each queue. From the Class of Service Configuration screen, type either 4 or 9 and press Enter.
