FIGURE 115 QoS, Create CEE Map dialog box

4. Select CEE from the Map Type list.

5. Configure the following CEE Map parameters in the CEE Map table:

• Name - Enter a name to identify the CEE map.

• Precedence - Enter a value between 1 - 100. This number determines the map’s priority.

• Priority Flow Control check box - Check to enable priority flow control on individual priority

groups.

• CoS - Enter a Class of Service value to correspond to the Priority Group ID rows. All of the

eight CoS values (0-7) must be used in a CEE map. Duplicate CoS values in two or more

priority groups are not allowed.

NOTE

You can only edit CoS fields that are displayed with a green tick mark.

% Bandwidth (optional) - Enter a bandwidth value for priority group (PG) IDs 0-7. You must

map each CoS to at least one of the PG IDs. Use a comma and a space to separate

multiple CoS values, as shown in Figure 115.

Note the following points:

• You cannot define a bandwidth percentage for Strict Priorities (PG ID 15.0 - 15.7). The

total % Bandwidth for PG ID 15.0-15.7 must equal 0%.

• If you set a CoS value to one or more of the PG IDs 0-7 and you set Priority Flow

Control to Enabled, you must also enter a non-0% bandwidth percentage. The total %

Bandwidth must equal 100%.

• For PG IDs 0-7 that do not have an assigned CoS value or PFC enabled, the %

Bandwidth must be 0%.
