- In the FC Configuration area, set Enable FC to Enable so that you can perform FC configuration.
- Configuring the FC Working Mode
The FC working mode indicates the working relationship between the FC switch planes of a pair of switch modules (2X/3X or 1E/4E). The value is NPV, Switch, or FSB. Table 1 describes the parameters.
Table 1 Parameter description Parameter
Description
NPV
indicates that the FC switch is in transparent transmission mode and connects to other switch using an NP_port.
Switch (FCF)
indicates that the FC switch is in FCF mode and can connect to storage devices.
FSB
The FCoE switch running FIP snooping is called a FIP Snooping Bridge (FSB). The FSB is used to limit the FCoE traffic forwarding from the servers to the Fiber Channel Forwarder (FCF), protecting FC devices against malicious attacks.
In FSB mode, an aggregation link is added to each FC SAN FCoE port. Therefore, aggregation links must be configured on the interconnected FCF switch.
- (Optional) Configuring FCoE interface Data Center Bridging (DCB)
NOTE: Perform this configuration only when FCoE interfaces are used. If only FC interfaces are used, ignore this configuration.

- (Optional) Configuring the Data Center Bridging Exchange Protocol (DCBX)
Table 2 describes the parameters.
Table 2 Parameter description Parameter
Description
Enable DCBX
- enable: DCB devices at the two ends of a link can automatically discover each other and exchange DCB configuration.
- disable: DCB devices at the two ends of a link cannot automatically discover each other and exchange DCB configuration.
The default value is enable.
DCBX version
The version must be consistent with that of a downstream device.
- IEEE
- intel-oui
The default value is intel-oui.
- Configuring Priority-based Flow Control (PFC)
Table 3 describes the parameters.
Table 3 Parameter description Parameter
Description
PFC work mode
- auto: The local PFC and peer PFC parameters are exchanged by using the DCBX function. If the negotiation at the two ends is successful, the PFC function takes effect; otherwise, the PFC function does not take effect. When the peer device is set to accept the DCB negotiation result, you can modify the DCB parameter configuration on the peer device to ensure that the configurations on both sides are the same.
- manual: You need to manually configure the PFC parameters on the local and peer devices and ensure that the configurations on both sides are the same. If the peer device does not support the DCBX function, set the parameter to manual.
NOTE:When the PFC working mode is set to auto, set Enable DCBX to enable.
PFC priority
Indicates whether to enable the PFC priority configuration function.
- Configuring Enhanced Transmission Selection (ETS)
Table 4 describes the parameters.
Table 4 Parameter description Parameter
Description
PG ID
Specifies the name of the priority group. PG0, PG1, and PG15 cannot be deleted.
DRR weight
Set this parameter when PGs except PG15 use the Deficit Round Robin (DRR). The value ranges from 1 to 99. A greater weight indicates a higher priority.
The sum of the DRR weights of PG0 and PG1 is 100 and the default value is 50.
Enable PG traffic shaping
Allows users to customize traffic policies to shape the traffic of all packets that pass through a port.
- CIR: indicates the priority group shaping committed information rate (CIR). The value ranges from 64 to 100,000,000 kbit/s. The value of CIR must be smaller than or equal to the value of PIR.
- PIR: indicates the priority group Shaping peak information rate (PIR). The value ranges from 64 to 100,000,000 kbit/s. The value of PIR must be greater than or equal to the value of CIR.
- CBS: indicates the committed burst size (CBS). The value ranges from 10000 to 536,870,912 bytes. The value of CBS must be smaller than or equal to the value of PBS.
- PBS: indicates the peak burst size (PBS). The value ranges from 10000 to 536,870,912 bytes. The value of PBS must be greater than or equal to the value of CBS.
Queues
Specifies the priority queue of a priority group. By default, queues 0, 1, 2, 4, and 5 belong to PG0, queues 6 and 7 belong to PG15, and queue 3 belong to PG1.
Queue Configuration
Specifies the name of the priority queue.
PG
Specifies the priority group of a queue.
Queue scheduling mode
- PQ: indicates priority queuing (PQ). Queues are scheduled according to priorities. Queues with lower priories are processed only after all the queues with higher priorities are empty. The PQ scheduling mechanism, however, may result in starvation of packets in queues with lower priorities if queues of higher priorities are full for a long time.
- DRR: indicates deficit round robin (DRR). Queues are scheduled in a polling manner based on the queue weight. The DRR scheduling mechanism schedules queues in a polling manner to ensure service time for each queue. Assume that there are eight queues, each of which is assigned a weight (w7, w6, w5, w4, w3, w2, w1, and w0). The weight indicates the percentage of resources for each queue. For example, for a 100 Mbit/s port, the weights of the queues are 50, 50, 30, 30, 10, 10, 10, and 10, respectively. This ensures that the queue with the lowest priority is assigned 5 Mbit/s bandwidth, preventing the starvation of packets in queues with lower priorities.
The default value is PQ.
Enable queue traffic shaping
Allows users to customize traffic policies to shape the traffic of a type of packets (based on the simple traffic classification) that pass through a port, implementing traffic shaping for services, such as voice, data, video services.
- CIR: indicates the priority group shaping committed information rate (CIR). The value ranges from 64 to 100,000,000 kbit/s. The value of CIR must be smaller than or equal to the value of PIR.
- PIR: indicates the priority group Shaping peak information rate (PIR). The value ranges from 64 to 100,000,000 kbit/s. The value of PIR must be greater than or equal to the value of CIR.
- CBS: indicates the committed burst size (CBS). The value ranges from 10000 to 536,870,912 bytes. The value of CBS must be smaller than or equal to the value of PBS.
- PBS: indicates the peak burst size (PBS). The value ranges from 10000 to 536,870,912 bytes. The value of PBS must be greater than or equal to the value of CBS.
The queue traffic shaping function is disabled by default.
