Configuring Quality of Service
QoS Queue
The Queue page contains the following fields:
❏
Strict Priority — Specifies whether traffic scheduling is based strictly on queue priority.
❏
WRR — Assigns WRR weights to queues. This field is enabled only for queues in WRR
queue mode. If a queue is set to 0 weight, the queue is not operational and is effectively
closed. Each queue has a weight range, queues 1-3 have the range 0-255, and queue 4
has the range 1-255.
❏
Queue — Indicates the queue for which the SP or WRR is defined.
❏
WRR Weight — Defines the amount of WRR Weight defined for the queue. The WRR
field can only be configured if the Per Port Shaping Type field was selected in the
Bandwidth Settings page was defined.
❏
% of WRR Bandwidth — Displays the amount of bandwidth the selected queue is
currently consuming.
2. Select Strict Priority or WRR fields.

Defining Rate Limiting

Rate limiting lets network managers manage network traffic based on bandwidth. Interfaces are
assigned a maximum bandwidth percentage by which packets are transmitted or received.
Packets that exceed the defined traffic rate are dropped. Bandwidth management or rate limiting
uses:
■
Committed Burst Size — Indicates the maximum number of data bits transmitted within a
specific time interval.
■
Committed Information Rate — Indicates the rate at which data is transmitted using Frame
Relay Services (FRS). The rate is averaged over a minimum time increment.
To define rate limiting:
1. Click QoS > General > Bandwidth Settings. The Bandwidth Settings page opens:
13-4
. The queue settings are defined, and the device is updated.
