Priority Marking and Queue Scheduling Configuration Example
Network requirements
As shown in Figure 1-11, an enterprise network connects all the departments through an
Ethernet switch. Clients PC 1 through PC 3 are connected to GigabitEthernet 1/0/1 of the
switch; clients PC 4 through PC 6 are connected to GigabitEthernet 1/0/3 of the switch.
Server 1 (the database server), Server 2 (the mail server), and Server 3 (the file server) are
connected to GigabitEthernet 1/0/2 of the switch.
Configure priority marking and queue scheduling on the switch to mark traffic flows
accessing Server 1, Server 2, and Server 3 with different priorities respectively and assign
the three traffic flows to different queues for scheduling.

Configuration procedure
1) Define an ACL for traffic classification
# Create ACL 3000 and enter advanced ACL view.
<Sysname> system-view
[Sysname] acl number 3000
# Define ACL rules for classifying packets based on destination IP addresses.
[Sysname-acl-adv-3000] rule 0 permit ip destination 192.168.0.1 0
[Sysname-acl-adv-3000] rule 1 permit ip destination 192.168.0.2 0
[Sysname-acl-adv-3000] rule 2 permit ip destination 192.168.0.3 0
[Sysname-acl-adv-3000] quit
2) Configure priority marking
# Mark priority for packets received through GigabitEthernet 1/0/2 and matching ACL 3000.
