Level 3 (Critical Applications) must be set to the highest level to ensure that FCoE traffic is given the
highest priority.

2 Create an access control list (ACL) in the switch to allow FCoE (Ethernet protocol number 0x8906) and
FCoE Initiation Protocol (FIP) (Ethernet Protocol 0x8914) packets to pass through the switch.
This rule is also applied to the DCBX traffic classifier (created in a later step). FCoE and FIP packets on
the switch receive the highest priority because they are mapped to 802.1p priority value 3.

3 Create a traffic classifier rule called DCBX with the operator class OR, and map it to ACL 4000, which
was created in the previous step.

4 Create a traffic behavior named DCBX and configure it to mark packets with an 802.1.p priority of 3.

5 Create a QoS policy that associates the traffic classifier created in step 3 with the traffic behavior created
in step 4, and specify that this classifier-behavior mode is associated with DCBX.

Configure Interface FCoE Parameters
To enable FCoE traffic to be passed to the CNAs of the management servers and to each enclosure, you
must configure the interface with LLDP, DCBX support, and the previously created QoS policy.
Procedure
1 In system-view, configure priority flow control and spanning tree.
To prevent FCoE packets from being dropped, enable priority flow control and ensure that any packet
with the dot1p classifier of 3 is not dropped and is forwarded. Also, setting the interfaces to edge ports in
