632 CHAPTER 58: QOS CONFIGURATION
Configuration Example ■ GigabitEthernet1/0/1 is accessed to the network segment 10.1.1.1/24.
■ Perform the RED queue scheduling algorithm for all the inbound traffic from
10.1.1.1/24
■ Set the parameters as follows: the packets are dropped at random when the
queue length exceeds 64 kbytes, all packets are dropped when the queue
length exceeds 128 kbytes, and the drop probability is 20%.
Configuration procedure:

Configuration
Prerequisites
■ ACL rules used for traffic identifying are defined. Refer to the ACL module in
the book for defining ACL rules
■ The ports that needs this configuration are specified
Configuration Procedure
of Traffic Statistics
acl-rule: Applied ACL rules which can be the combination of various ACL rules.
Type-A I/O Modules’ way of combination is described in
Table 496, and
non-type-A I/O Modules’ way of combination is described in Table 497.
