DSCP Translation
To preserve the proper QoS Level of the packet and avoid high priority packets from being delayed or
dropped, a DSCP translation policy for traffic can be used. When a DSCP translation policy is enabled,
the QoS Level value is converted to a DSCP value according to the specified mapping rules. [8]
This page allows the user to configure basic QoS DSCP translation settings for all switches. DSCP
translation can be done in
Ingress
or
Egress
.
