Manage individual port settings
For each individual port, you can set the port priority, set rate limits for incoming and
outgoing traffic, set the port speed (by default, the speed is set automatically), enable
flow control, and change the port name label.
Set rate limits for a port
You can limit the rate of incoming (ingress) traffic, outgoing (egress) traffic, or both on
a port to prevent the port (and the device that is attached to it) from taking up too much
bandwidth on the switch. Rate limiting simply means that the switch slows down all
traffic on a 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, for example, see degraded video stream
quality, sluggish response times during online activity, and other problems.
You also can set port rate limits (the same feature) as part of the Quality of Service
configuration on the switch (see Set the quality of service mode and port rate limits on
page 24).
To set rate limits for incoming and outgoing traffic on a port:
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.
A login window opens.
3. Enter the device management password.
The password is the one that you specified the first time that you logged in. The
password is case-sensitive.
The HOME page displays.
The PORT STATUS pane displays on the right or the bottom of the HOME page,
depending on the size of your browser window.
A port that is in use shows as UP. A port that is not in use shows as AVAILABLE.
4. Select the port.
The pane displays detailed information about the port.
5. Click the EDIT button.
The EDIT PORT page displays for the selected port.
If the QoS mode on the switch is Port-Based (the default setting), the Priority menu
displays on the page. If the QoS mode is 802.1P/DSCP, the Priority menu does not
display.
