3.5.46 Main Menu->QoS (Quality of Service Configuration Menu)
The ES3000 implements IEEE 802.1p Quality of Service (QoS) processing. QoS policies examine
packets and classify them. The classification is used to drop packets or to assign markers to the
packets. The markers are Class of Service (CoS) Priority, Type of Service (ToS) Precedence and
Differentiated Services Code Points (DSCP). For each port, the outgoing packets are then placed in
four output queues based on CoS priority or DSCP value. The queues are serviced using a weighted
round robin algorithm.
Quality of Service defines the methods to improve network performance by segregating traffic.
Configure the switch for specific traffic to take priority by using either the VLAN tags (port-based) or
DSCP (DiffServ).
