Viewing and configuring QoS level and DSCP mapping

You can view and configure the mapping between the QoS levels and the DSCP. When no traffic filter is used, the DSCP of bridged IP traffic is reset according to the QoS level as the traffic egresses. Changes to the mapping table do not take effect until you reboot the switch.


Note Note: Nortel Networks recommends not changing the default values. If you change the values, make sure that the values are consistent on all other Passport switches and other devices in your network. Inconsistent mapping of table values can result in unpredictable service levels.

To view and configure QoS level and DSCP mapping:


From the Device Manager menu bar, choose QOS > QOS > Egress QosToDscp.


The QOS dialog box opens with the Egress QosToDscp tab displayed.

The table below describes the Egress QosToDscp tab fields.


Field Description
QosLevel
QoS level of the outgoing packet.
OutDscp
Equivalent value of the DiffServ codepoint (in decimal format).
OutDscpBinaryFormat
Equivalent value of DiffServ codepoint in binary format.
