Moxa PT-7528-8MST-16TX-4GSFP-WV-WV [59/116] Type 2

PT-7528 Series Advanced Settings

4-39

NOTE

The priority of an ingress frame is determined in the following order:

1. Inspect TOS

2. Inspect CoS

3. Port Priority

NOTE

The designer

can enable these classifications individually or in combination. For instance, if a “hot” higher

priority port is required for a network design,

Inspect TOS and Inspect CoS

can be disabled. This setting

leaves only port default priority active, which results in all ingress frames being assigned the same priority on

that port.

Type 2

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 t

he 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 egre

the switch as soon as possible.

Inspect Port Highest Priority

Setting Description Factory Default

Enable/Disable Enables or disables the priority inspection of each port Disabled

Inspect TOS

Setting Description Factory Default

Enable/Disable Enables or disables the Moxa switch for inspecting Type of

Service (TOS) bits in the IPV4 frame to determine the priority of

each frame.
