Configure the interfaces participating in DCB. In this example, this includes the server-facing storage
interfaces (Eth 1/1/1-1/1/4) and the VLTi interfaces (Eth 1/1/49-1/1/52).
Note: The commands shown are in addition to the interface configuration commands issued in the preceding
sections.
1. Disable transmit and receive link level flow control using the flowcontrol receive | transmit
off commands.
2. Assign the PFC service policy and enable priority flow control on the interfaces.
3. Assign the ETS service policy and enable ETS mode on the interfaces.
4. Apply the queuing traffic class map to the interfaces.
5. When the configuration is complete, exit configuration mode and save the configuration with the end
and write memory commands.
