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.

Interface

Indicates the interface for which the queue

shaping information is displayed. The possible field values
are:

Port

Indicates the port for which the bandwidth

settings are displayed.

LAG

Indicates the LAG for which the bandwidth

settings are displayed.

Ingress Rate Limit Status

Indicates if rate limiting is

defined on the interface.

Egress Shaping Rate on Selected Port

Indicates if rate

limiting is enabled on the interface.

Committed Information Rate (CIR)

Defines CIR as the

queue shaping type. The range is 641,000,000 Kbps.

Committed Burst Size (CBS)

Defines CBS as the queue

shaping type. The possible field value is 409616,769,020
bits.

Use the Add to List button 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

QoS > Advanced Mode

Advanced QoS mode provides rules for specifying flow
classification and assigning rule actions that relate to
bandwidth management. The rules are based on the ACLs
(see Access Control Tab). This feature has been added to
version 1.2 of the SRW2024/SRW2016 and version 1.1 of
the SRW224G4/SRW248G4.

QoS > Advanced Mode

MAC ACLs and IP ACLs can be grouped together in more
complex structures, called policies. Policies can be applied
to an interface. Policy ACLs are applied in the sequence
they appear within the policy. Only a single policy can be
attached to a port.

In advanced QoS mode, ACLs can be applied directly to an
interface in Security > ACL Binding. However, a policy and
ACL cannot be simultaneously applied to an interface.

After assigning packets to a specific queue, services such
as configuring output queues for the scheduling scheme,
or configuring output shaping for burst size, CIR, or CBS
per interface or per queue, can be applied.

Out of Profile DSCP Assignments

This button opens up
