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
classification. By properly configuring the output queues, the following basic mode services can be set:
Minimum Delay — The queue is assigned to a strict priority policy, and traffic is assigned to the highest priority queue.
Best Effort — Traffic is assigned to the lowest priority queue
Bandwidth Assignments — Bandwidths are assigned by configuring the WRR scheduling scheme and choosing the
right weights.
12.1.2.2 Advanced QoS Mode
Advanced QoS mode provides rules for specifying flow classification 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
configuring 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 fields for enabling or disabling QoS. In addition, the Trust mode can be selected. The Trust
mode relies on predefined fields within the packet to determine the egress queue settings.
To enable QoS and define basic settings:
1. Click
System > Quality of Service > General Settings > CoS Settings. The CoS Settings Page opens:
