8-Port 10/100/1000 Gigabit Switch with Webview
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.
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.
Rate Limit (62-1000000 Kbps) Defines the amount of
bandwidth assigned to the interface. The possible field
values are 62-1000000 Kbps.
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 possible field value is 64 -
1,000,000 Kbps.
Committed Burst Size (CBS) Defines CBS as the queue
shaping type. The possible field value is 4096-16,769,020
bits. Committed Burst Size cannot be configured on FE
ports.
The Add to List button adds 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
Access Control Lists (see Access Control Tab).
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 the 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.

the Out of Profile DSCP screen.
