Applying a DCB Map on a Port

When you apply a DCB map with PFC enabled on a switch interface, a memory buffer for PFC-enabled priority traffic is automatically allocated. The buffer size is allocated according to the number of PFC-enabled priorities in the assigned map.

To apply a DCB map to an Ethernet port, follow these steps:

Apply the DCB map on the Ethernet port to configure it with the PFC and ETS settings in the map; for example:

DellEMC(config-if-te-1/1)# dcb-map SAN_A_dcb_map1 Repeat Steps 1 and 2 to apply a DCB map to more than one port.

You cannot apply a DCB map on an interface that has been already configured for PFC using the pfc priority command or which is already configured for lossless queues (pfc no-drop queues command).
