When configuring the OM 1200 ESM module, you map 802.1p customer network priority levels to Optical Ethernet class-of-service (COS) values. You probably map the priority levels according to a service level agreement that specifies the priorities.
To map 802.1p priority levels to Optical Ethernet class-of-service (COS) values:
| The OEL2 dialog box opens with the Transparent Domain tab displayed. |
| Use the TDIndex column to identify the transparent domains in the table. |
| The PriorityMap column contains an array of eight numbers separated by colons (:). |
Figure 2 :  LAN Services tab
| The position of the number from the left represents the 802.1p priority of an incoming packet. The number at that position represents the transparent domain priority that will be assigned to the packet. This relationship is shown in the example in Figure 3. |
