b. Configure rate limiting based on all traffic on a network segment.
To reserve sufficient bandwidth resources for department A as services grow,
configure rate limiting for department B. The Internet access rate in department B
cannot exceed 2 Mbit/s and the download rate cannot exceed 4 Mbit/s.
Configure an ACL on the egress router to allow packets from department B to pass
1
through.
[Router] acl 2222
[Router-acl-basic-2222] rule permit source 192.168.20.0 0.0.0.255
[Router-acl-basic-2222] quit
Configure rate limiting on LAN-side interfaces of the egress router to limit the Internet
2
access rate and download rate.
[Router] interface GigabitEthernet 0/0/1
[Router-GigabitEthernet0/0/1] qos car inbound acl 2222 cir 2048
[Router-GigabitEthernet0/0/1] qos car outbound acl 2222 cir 4096
[Router-GigabitEthernet0/0/1] quit
The configuration procedure on GE0/0/2 is similar to that on GE0/0/1.
For details on rate limiting configuration and commands, see "Traffic Policing and
Traffic Shaping Configurations" and configuration examples in the corresponding
Configuration Guide – QoS
based on the version of the device.
