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 80.1p Settngs
80.1p Value Prorty 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 Settngs
DSCP Value (0-6) Prorty
46 high
34 medium
24 normal
All others low
DSCP Value Indicates the Differentiated Services Code
Point value in the incoming packet.
Prorty Maps the DSCP value to the selected priority
level.
Click Save Settngs to save any changes.
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.
