CoS - Click the CoS cell to launch the Edit CoS dialog box, where you can select and assign
one or more priorities (PG ID 15.0 through 15.7).
All of the eight CoS values (0-7) must be used in a DCB map. Duplicate CoS values in two
or more priority groups are not allowed.
You can only edit CoS fields that are displayed with a green tick mark.
% Bandwidth (optional) - While in the Edit CoS dialog box, enter a bandwidth value for PG
IDs 15.0 to 15.7. You must map each CoS to at least one of the PG IDs.
Note the following points:
•
You cannot define a bandwidth percentage for strict priorities (PG ID 15.0 - 15.7). The
total bandwidth percentage for PG ID 15.0 through 15.7 must equal 0.
•
If you set a CoS value to one or more of the PG IDs 0-7, you must also enter a non-zero
bandwidth percentage. The total bandwidth percentage must equal 100.
•
For PG IDs 0-7 that do not have an assigned CoS value or PFC enabled, the bandwidth
percentage must be 0.
