QoS Mode Priority Diagram

802.1p

802.1p QoS Mode allows you to specify data packet priority based on the 802.1p value in VLAN priority tag of the packet. Users can map 802.1p to one of 4 priority queues.

Prioritize Traffic

Allows you to select a traffic prioritization setting. The default value is Custom.

802.1p Settings

The default 802.1p settings are shown in the following table:

Default 802.1p Settings

802.1p Value	Priority Level
0	normal
1	low
2	low
3	normal
4	medium
5	medium
6	high
7	high

Port-Based

Port-Based QoS mode allows you to set priority levels for each port.

Port-Based Settings

This allows customization of priority levels for specific ports. By default, all ports are set to high priority.

DSCP

The Switch supports a common method of prioritizing IP traffic to meet application requirements. Traffic priorities can be mapped to one of 4 priority queues based on the DSCP (Differentiated Services Code Point) value.

DSCP Settings

DSCP Settings enable mapping DSCP values to specific priority levels. The default DSCP settings are shown in the following table:

DSCP Settings

DSCP Value (0-63)	Priority
46	high
34	medium
24	normal
All others	low

DSCP Value  Indicates the Differentiated Services Code Point value in the incoming packet.

Priority  Maps the DSCP value to the selected priority level.

STP > STP Settings

The Spanning Tree Algorithm (STA) can be used to detect and disable network loops, and to provide backup links between switches, bridges or routers. This allows the Switch to interact with other bridging devices (that is, an STA-compliant switch, bridge or router) in your network to ensure that only one route exists between any two stations on the network, and provide backup links which automatically take over when a primary link goes down.
