4.8.2 QoS Basic Mode
Quality of Service (QoS) allows to give preferential treatment to certain types of traffic at the
expense of others. Without QoS, the switch offers best-effort service to each packet, regardless of
the packet contents or size sending the packets without any assurance of reliability, delay bounds,
or throughput.
QoS mode supports two modes: 802.1p and DSCP.
Global Settings
The Global Settings page allows you to configure the trust mode to a port selection. To access this
page, click QoS > QoS Basic Mode > Global Settings.
The function is only available when QoS Properties is set to Basic.
