To use the out-of-profile DSCP exceed action, remap the DSCP value in the Out Of
Profile DSCP Mapping Table. Otherwise the action is null, because the DSCP value
in the table remaps the packets to itself by factory default.

enables sets the change-the-DSCP-value of traffic entering or leaving the
switch.
This feature changes the DSCP tags for incoming traffic switched between
trusted QoS domains. Changing the DSCP values used in one domain, sets the
priority of that type of traffic to the DSCP value used in the other domain to
identify the same type of traffic.
These settings are active when the system is in the QoS basic mode, and once
activated they are active globally.
For example: Assume that there are three levels of service: Silver, Gold, and
Platinum and the DSCP incoming values used to mark these levels are 10, 20, and
30 respectively. If this traffic is forwarded to another service provider that has the
same three levels of service, but uses DSCP values 16, 24, and 48, Out of Profile
DSCP Mapping changes the incoming values as they are mapped to the outgoing
values.
To m a p D S C P v a l u e s :
STEP 1 Click Quality of Service > QoS Advanced Mode > Out of Profile DSCP Mapping.
The Out of Profile DSCP Mapping Page opens. DSCP In displays the DSCP value
of the incoming packet that needs to be remarked to an alternative value.
STEP 2 Select the DSCP Out value to where the incoming value is mapped.
STEP 3 Click Apply. The switch is updated with the new DSCP remarking table.
