Moxa EDS-405A-EIP-T [51/109] Qos classification

Moxa Managed Ethernet Switches Featured Functions

3-39

SMV

Setting Description Factory Default

High/Medium/Normal/

Low

The priority sequence is High>Medium>Normal>Low. We

recommend setting SMV packets to high priority.

Medium

PTP

Setting Description Factory Default

High/Medium/Normal/

Low

The priority sequence is High>Medium>Normal>Low. Normal

QoS Classification

There are two QoS classification settings depending on the specific model of the switch.

Type Models Supported

Type 1 EDS-400A series, EDS-505A/508A/510A/G509, EDS-P506A-4PoE/P510/P510A-8PoE,

EDS-600 series, IKS-G6524/G6824, ICS-G7000 series

Type 2 EDS-516A/518A, EDS-728/828, IKS-6726/6726-8PoE/6728

Type1

The Moxa switch supports inspection of layer 3 TOS and/or layer 2 CoS tag information to determine how to

classify traffic packets.

Queuing Mechanism

Setting Description Factory Default

Weight Fair The Moxa switch has 4 priority queues. In the weight fair

scheme, an 8, 4, 2, 1 weighting is applied to the four priorities.

This approach prevents the lower priority frames from being

starved of opportunity for transmission with only

a slight delay

to the higher priority frames.

Weight Fair

Strict In the Strict-priority scheme, all top-priority frames egress a

port until that priority’s queue is empty, and then the next

lower priority queue’s frames egress. This approach can cause

the lower priorities to be starved of opportunity for transmitting

any frames but ensures that all high priority frames will egress

the switch as soon as possible.
