This section contains the following topics:
•QoS Properties
• Queue Scheduling
•CoS to Queue
•DSCP to Queue
• Bandwidth Management
• TCP Congestion Avoidance
QoS Properties
To set the default CoS value on incoming, untagged packets:
1
Click Network Administration > Quality of Service > Global Settings >
QoS Properties .
The default CoS values for all interfaces are displayed.
2 To modify the CoS value for an interface, click Edit.
3 Select a port, click its Edit icon and enter the fields:
–
Interface — Select a port or LAG if required.
–
Set Default CoS — Enter the default CoS tag value for untagged
packets. The default CoS tag value is
src .
Queue Scheduling
The switch supports eight queues for each interface. Queue number eight is
the highest priority queue. Queue number one is the lowest priority queue.
Traffic Limitation Methods
There are two ways of determining how traffic in queues is handled, Strict
Priority and Weighted Round Robin (WRR):
• Strict Priority — Egress traffic from the highest-priority queue is
transmitted first. Traffic from the lower queues is processed only after the
highest queue has been transmitted, thus providing the highest level of
priority of traffic to the lowest-numbered queue.
