Configuration procedure
1) Define an ACL for traffic classification.
# Create ACL 2000 and enter basic ACL view.
system-view
[Sysname] acl number 2000
# Define a rule for the packets with 192.168.0.1 as the source IP address.
[Sysname-acl-basic-2000] rule permit source 192.168.0.1 0
[Sysname-acl-basic-2000] quit
2) Configure traffic policing and rate limiting
# Set the maximum rate of outbound packets sourced from the marketing department to 64 kbps.
[Sysname] interface Ethernet1/0/2
[Sysname-Ethernet1/0/2] line-rate inbound 64
[Sysname-Ethernet1/0/2] quit
# Set the maximum rate of outbound IP packets sent by PC 1 in the R&D department to 640 kbps.
[Sysname] interface Ethernet1/0/1
[Sysname-Ethernet1/0/1] traffic-limit inbound ip-group 2000 640 exceed drop
Configuration Example of Priority Marking and Queue Scheduling
Network requirements
As shown in Figure 1-10 , an enterprise network connects all the departments through an Ethernet
switch. Clients PC 1 through PC 3 are connected to Ethernet 1/0/1 of the switch; clients PC 4 through
PC 6 are connected to Ethernet 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 Ethernet 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.
