Manage Flow Control For A Port - NETGEAR GS305EP User Manual

Gigabit Ethernet Smart Managed Plus Switches Series 3XXEP and 3XXEPP
The switch services traffic from ports with a critical priority before traffic from ports with
a high, medium, 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 the priority for a port (the same feature) as part of the Quality of Service
configuration on the switch (see Use port-based quality of service and set port priorities
on page 22).
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.

Manage flow control for a port

IEEE 802.3x flow control works by pausing a port if the port becomes oversubscribed
(that is, the port receives more traffic than it can process) and dropping all traffic for
small bursts of time during the congestion condition.
