Figure 4-56: QoS Configuration - 802.1Priority

This page includes the following fields:

OBJECT

DESCRIPTION

First Come First Service

The sequence of packets sent is depend on arrival order.

 

 

All High before Low

The high priority packets sent before low priority packets.

 

 

 

Select the preference given to packets in the switch's higher-priority

 

queue. These options represent the number of higher priority packets

 

sent before one lower priority packet is sent.

Weighted Round Robin

For example, 8 Highest : 4 SecHigh : 2 SecLow : 1 Lowest means that

 

the switch sends 8 highest priority packets before sending 4 second

 

high priority packet, before sending 2 second low priority packet, before

 

sending 1 lowest priority packet.

 

 

802.1p priority [0-7]

Set up the COS priority level 0~7—High, Middle, Low, Lowest.

 

 

NOTE: 802.1p Priority:

Priority classifiers of the Switch forward packet. COS range is from 0 to 7. Seven is the high class. Zero is the less class. The user may configure the mapping between COS and Traffic classifiers.

QoS PerPort Configuration

Configure the priority level for each port. With the drop-down selection item of Priority Type above being selected as Port-based, this control item will then be available to set the queuing policy for each port.
