With the Comware products you will want to write an ACL to select the specific traffic you want to remark, and then you will need to create a traffic classifier, traffic behavior, a QoS policy, and then apply it to an interface.
This ACL/QoS policy example is written to select all FCoE data packets and all FCoE FIP packets. The classifier and behavior are used in the QoS policy to mean – “All FCoE data packets and all FCoE FIP packets should be remarked with a 802.1p values of 3”. To apply the QoS policy it is enabled on an interface.
This example uses Ethertype as the selection method. Depending on the ACL # you choose you potentially have the following match criteria to choose from:
Match Criteria:
Source IPv4/IPv6 address
Destination IPv4/IPv6 address
Packet priority
Protocol number
Other Layer 3 and Layer 4 header fields
Layer 2 source MAC addresses
Layer 2 destination MAC addresses
802.1p priority
Link layer protocol type
ACL/QoS Policy Example:
acl number 4444 name DCBX
rule 0 permit type 8906 ffff
rule 5 permit type 8914 ffff
traffic classifier DCBX operator or
if-match acl 4444
traffic behavior DCBX
remark dot1p 3
qos policy DCBX
classifier DCBX behavior DCBX mode dcbx
interface ten-gigabitethernet 1/0/4
qos apply policy DCBX outbound
Check out the Configuring Priority Marking section in the ACL and QOS Configuration Guide which also has some good examples.
