• Trust
Controls whether a specific DSCP value is trusted. Only frames with trusted
DSCP values are mapped to a specific QoS class and Drop Precedence Level.
Frames with untrusted DSCP values are treated as a non-IP frame.
• QoS Class
QoS Class value can be any of (0-7)
• DPL
Drop Precedence Level (0-1)
4.4.4.3 DSCP Translation
This page allows you to configure the basic QoS DSCP Translation settings for all switches. DSCP translation can be done in
Ingress or Egress. The DSCP Translation screen in Figure 4-4-4-3 appears.
Figure 4-4-4-3: DSCP Translation Page Screenshot
The page includes the following fields:
Object Description
• DSCP
Maximum number of supported DSCP values are 64 and valid DSCP value
ranges from 0 to 63.
• Ingress
Ingress side DSCP can be first translated to new DSCP before using the DSCP
for QoS class and DPL map.
There are two configuration parameters for DSCP Translation –
