QoS > DSCP Settings
QoS > DSCP Settings
The DSCP Settings screen allows you to map Differentiated
Services Code Point (DSCP) values to specific queues.
DSCP Indicates the DSCP value in the incoming packet.
Select a DSCP value from the drop-down menu to map
that value to the associated queue. You can select the
DSCP value for the High, Medium, and Normal priority
queues. The DSCP values for the Low priority queue are
selected automatically based on the other DSCP values.
Queue
The queue (1-4) to which the DSCP value is being
mapped.

QoS > Bandwidth
QoS > Bandwidth
The Bandwidth screen allows network managers to define
the bandwidth settings for a specified egress or ingress
interface. Modifying queue scheduling affects the queue
settings globally. The Bandwidth screen is not used with the
Service mode, as bandwidth settings are based on services.
Queue shaping can be based per queue and/or per
interface. Shaping is determined by the lower specified
value. The queue shaping type is selected in the Bandwidth
screen.

Configuration Using the Web-based Utility
Interface
The interface for which the queue shaping
information is displayed. Either select Unit No and select
the unit number and port from the drop-down menus,
or select LAG and select the LAG number from the drop-
down menu.
Enable Ingress Rate Limit Status
is defined on the interface.
Enable Egress Shaping Rate
enabled on the interface.
Committed Information Rate (CIR)
the queue shaping type. The allowed values are 64 to
62500 Kbps for the 10/100 ports and 64 to 1000000 Kbps
for the Gigabit ports.
Committed Burst Size (CBS)
queue shaping type. The possible field value is 406
to 15,76,020 bits. Commited Burst Size cannot be
configured on FE ports.
Click Update to add the Bandwidth configuration to the
Bandwidth Table at the bottom of the screen.
QoS > Basic Mode
QoS > Basic Mode
The Basic Mode screen contains the following fields:
Trust Mode
Displays the trust mode. If a packet's CoS
tag and DSCP tag are mapped to different queues, the
Trust Mode determines the queue to which the packet is
assigned. Possible values are:
CoS Sets trust mode to CoS on the device. The CoS
•
mapping determines the packet queue
DSCP Sets trust mode to DSCP on the device. The
•
DSCP mapping determines the packet queue.
