Note:

When moving to and from basic and advanced QoS modes, some settings may be lost.

12.1.2.1 Basic QoS Mode

Basic Mode supports activating one of the following Trust settings:

VLAN Point Tag

DiffServ Code Point

None

In addition, a single IP-based ACL can be attached directly to the interface (see section on network security for more

information). Only packets that have a Forward action are assigned to the output queue, based on the specified

classication. By properly conguring the output queues, the following basic mode services can be set:

Minimum Delay — The queue is assigned to a strict priority policy, and trafc is assigned to the highest priority queue.

Best Effort — Trafc is assigned to the lowest priority queue

Bandwidth Assignments — Bandwidths are assigned by conguring the WRR scheduling scheme and choosing the

right weights.

12.1.2.2 Advanced QoS Mode

Advanced QoS mode provides rules for specifying ow classication and assigning rule actions that relate to bandwidth

management.

After assigning packets to a specific queue, services such as configuring output queues for the scheduling scheme, or

conguring output shaping for burst size, CIR, or CBS per interface or per queue, can be applied. In Advanced Mode packets

may egress with a different VPT tag than expected.

12.2 Enabling Quality of Service

This section contains the following topics:

Enabling Quality of Service

Mapping Queues

12.2.1 Enabling Quality of Service

The CoS Settings Page contains elds for enabling or disabling QoS. In addition, the Trust mode can be selected. The Trust

mode relies on predened elds within the packet to determine the egress queue settings.

To enable QoS and dene basic settings:

1. Click System > Quality of Service > General Settings > CoS Settings. The CoS Settings Page opens:
