Quality of service (QoS) – introduction
QoS conguration enables the switch to use resources more efciently
to ensure high-quality performance for critical applications. QoS is a
mechanism which is used to prioritize certain trafc as it is moves
through the switch. Trafc can be classied as High, Medium, Normal or
Low priority. This switch features both strict priority-based and weighted
round-robin (WRR) forwarding, with guaranteed bandwidth allocation for
the different QOS classes.
QoS conguration
Click “Quality of Service” under the Conguration menu. QoS
Conguration page appears on the screen.
The Queue Mode can be selected by ticking the radio button:
Strict : Higher priority frames take precedence over lower priority frames
during forwarding. In case of congestion, the lowest priority trafc is dropped
before higher priority frames. Head-of-queue blocking maybe encountered
by using this mode.
WRR : In this mode, all priorities can be guaranteed a share of the band-
width when the system is overloaded. The bandwidth sharing percentage
can be adjusted by specifying the four QOS class with different ratio in WRR
Weight, which appears after WRR is enabled in Queue Mode .
Note! WRR is selectable only when Jumbo Frame is disabled in
Ports / Settings.
The QoS Mode can be selected using the QoS Mode drop-down list:
QoS Disabled: QoS is turned off and all packets have equal priority.
802.1p: Packets are prioritzed using the content of the VLAN-tag.
DSCP/DiffServ : Packets are prioritized using the DSCP/DiffServ
(Differentiated Services Code Point) value.
Note: Only one QoS mode can be active at one time. It is not
possible, for example, to prioritise trafc using the DSCP/DiffServ
and 802.1p.
