For service processor boards, perform the following configurations in VLAN view.
Mark the packets
matching Layer 3 ACL
rule with priority
Remove the mark
Caution:
Before executing the traffic-priority command on a service processor board, you
must first configure traffic redirecting in Ethernet port view to redirect the packets of
a specific VLAN to the service processor board.
Before performing this configuration, you must first define the ACLs and configure
the DSCP-to-services mapping tables and the EXP-to-services mapping tables. For
configuration of the mapping tables, refer to section
Normally, when applying a rule, the system assigns a globally unique index to it for later
retrieval. Alternatively, you can choose to assign a system index to an ACL rule with this
command. However, as this value may change while the system is running, you are not
encouraged to manually assign system indexes to ACL rules.
