10.3.3 Queues Configuration on User Ports
From the Class of Service Queue Configuration screen (Figure 10-3), type 3 and press Enter.
The Edit Queue Configuration on User Ports screen (Figure 10-11) opens.
Type the number of the attribute you wish to configure and press Enter. Press Esc to return to
the Class of Service Queue Configuration screen.
The same set of configuration attributes applies to every user port.
1. Enable/Disable a Queue The 9145EMP has four queues: LLQ, Q3, Q2, Q1. This
function allows you to enable only the queues that are in use. Type the number of the
queue you wish to enable or disable. Press the Space bar to select Enabled or Disabled
and then press Enter.
NOTE: The LLQ cannot be disabled and the LLQ size cannot be set to zero (0).
2. Queue Size (in 8K-Byte) The queue size can be any value from 0KB to 2MB (from 8KB
to 2MB for LLQ). To change the queue size, type 2 for LLQ, 4 for Queue 3, 10 for Queue
2, or 16 for Queue 1. Type the new setting and press Enter.
Queues require a size parameter range between 0 and 250 (between 1 and 250 for LLQ).
If you enter an invalid size parameter, the message INVALID INPUT will appear at the
bottom of the screen.
3. Scheduling Scheme The 9145EMP 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. To change the schedule scheme, type 5 for Queue 3, 11 for Queue 2,
or 17 for Queue 1. Press the Space bar to select Strict Priority or Weighted Fair and then
press Enter.
4. Weight Parameters Queue 3, Queue 2 and Queue 1 require a Weight parameter range
between 0 and 1000. If WFQ is set as the scheduling method, a weight must be assigned
to each queue. The weight is proportional to the bandwidth that queue will receive. The
weight value can be of any range between 0-1000.
To change the queue weight, type 6 for Queue 3, 12 for Queue 2, or 18 for Queue 1. Type
the new setting and then press Enter.
NOTE: If you enter an invalid weight parameter, INVALID INPUT will appear at the bottom of the
screen.
5. Enable/Disable ED Drop Profile Every queue has two drop profiles associated with it.
(For more information about ED Drop Profiles, see ““Early Detect Drop Profiles” on
page 121.)
To enable or disable ED drop profiles, type 7 or 8 for Queue 3, 13 or 14 for Queue 2, or 19
or 20 for Queue 1. Press the Space bar to change the setting and press Enter.
6. Press Esc to return to the Class of Service Queue Configuration screen.
