Assigning a DCB map to a port or link aggregation group
The Edit Port dialog box - QoS tab allows you to assign DCB maps to ports and LAGs on a selected
switch.
NOTE
QoS maps are created using the Edit Switch dialog box, accessible from the DCB Configuration
dialog box.
A port can have either a DCB map or a Traffic Class map assigned to it, but it cannot have both.

The DCB Configuration dialog box displays, showing the status of all DCB-related hardware and
functions.
2. Select a port or LAG, and click Edit.
3. Click the QoS tab on the Edit Port or Edit LAG dialog box.

4. Click the Assign a map to < device_name > check box to assign the selected port to a DCB map.
If you do not select this check box, all QoS edit features are disabled.
5. Select DCB Map in the Map Type list.

•
PG - ID — Lists the priority group ID (15.0 through 15.7 and 0 through 7).
