NETGEAR MS108EUP - Set the Quality of Service Mode and Port Rate Limits; Use Port-Based Quality of Service and Set Port Priorities

Set the quality of service mode and port rate
limits
You can manually set the Quality of Service (QoS) modes to manage traffic:
•
Port-based QoS mode: Lets you set the priority (low, normal, medium, high, or
critical) for individual port numbers and lets you set rate limits for incoming and
outgoing traffic for individual ports. If broadcast filtering is enabled, you can also
set the storm control rate for incoming traffic for individual ports.
•
802.1P/DSCP QoS mode: Applies pass-through prioritization that is based on
tagged packets and lets you set rate limits for incoming and outgoing traffic for
individual ports. If broadcast filtering is enabled, you can also set the storm control
rate for incoming traffic for individual ports.
This QoS mode applies only to devices that support 802.1P and Differentiated
Services Code Point (DSCP) tagging. For devices that do not support 802.1P and
DSCP tagging, ports are not prioritized, but the configured rate limit is still applied.
You can limit the rate of traffic on a port, including incomine or outgoing traffic, or both,
to prevent the port and the device that is attached to it from taking up too much
bandwidth on the switch. Rate limiting, which you can set for individual ports in either
of these QoS modes, simply means that the switch slows down all traffic on the port so
that traffic does not exceed the limit that you set for that port. If you set the rate limit on
a port too low, you might notice degraded video stream quality, sluggish response
times during online activity, and other problems.
Use port-based quality of service and set port priorities
802.1P/DSCP is the default QoS mode on the switch, but you can also set port-based
QoS.
For each port, you can set the priority for both ingress (incoming) and egress (outgoing)
traffic. The switch services traffic from ports with a critical priority before traffic from
ports with a high, medium, normal, or low priority. Similarly, the switch services traffic
from ports with a high priority before traffic from ports with a medium or low priority.
If severe network congestion occurs, the switch might drop packets with a low priority.
You also can set port rate limits (the same feature) as part of the QoS configuration on
the switch (see Set
rate limits for a port on page 27).
To use the port-based QoS mode and set the priority and rate limits for ports:
1.
Open a web browser from a computer that is connected to the same network as the
switch, or connected directly to the switch through an Ethernet cable.
2. Enter the IP address that is assigned to the switch.
