Creating a DCB map

The procedure in this section applies only for Fabric OS versions earlier than Fabric OS 7.0.

When you create a DCB map, each of the Class of Service (CoS) options (0-7) must be mapped to
at least one of the Priority Group IDs (0-7) and the total bandwidth percentage must equal 100. All
QoS, DCB map, and Traffic Class map configurations apply to all ports in a LAG.

There can be, at the most, 16 entries in the Priority Group table. Eight of the entries are Strict
Priority entries with a Priority Group ID (15.0-15.7) and eight are user-definable entries with a
Priority Group ID of 0-7. Refer to

Table 61

for an example of priority group configuration.

NOTE

The 10 Gbps DCB/FC switch module can have only one DCB map.

1. Select Configure > DCB.

The DCB Configuration dialog box displays, showing the status of all DCB-related hardware and
functions.

2. Select a switch, and click Edit.

3. Click the QoS tab on the Edit Switch dialog box.

The QoS dialog box displays, as shown in

Figure 247
