page 53-94

OmniSwitch CLI Reference Guide

Configures the Differentiated Services Code Point (DSCP) for a policy condition. The DSCP value defines 
the six most significant bits of the DS byte in the IP header.

policy condition condition_name dscp {dscp_value[-value]} [mask dscp_mask]

policy condition condition_name no dscp

The name of the condition. May be an existing condition name or a new 
condition.

{dscp_value[-value]}

The DiffServ Code Point value, in the range 0–63. Use a hyphen to 
specify a range of DSCP values for the condition (for example, 10-20). 
Specifying a range is not supported on the OmniSwitch 6800.

The mask for the DiffServ Code Point, in the range 0–63. This parame-
ter is not supported on the OmniSwitch 6800, 6850, and 9000.

OmniSwitch 6400, 6850, 6855, 9000, 9000E

• Use the no form of this command to remove a DSCP value from a condition; however, at least one 

classification parameter must be associated with a condition.

• If a DSCP value is specified, a ToS value may not be specified.

• On the OmniSwitch 6800, 6850, and 9000 the mask parameter is not specified with this command. 

When a DSCP policy condition is configured on one of these switches, QoS automatically calculates 
the appropriate mask value.
