Configuring Rate Limiting
a. Configure rate limiting based on the IP address.
Configuring IP address-based rate limiting on the switch is complicated and
consumes a lot of hardware ACL resources. Therefore, You can configure IP address-
based rate limiting on the egress router's physical interfaces connecting to the core
switches.
Because bandwidth resources are limited and service traffic transmission must be
ensured, the upload and download rate of each intranet IP address cannot exceed
512 kbit/s.
On GE0/0/1, configure IP address-based rate limiting for network segments
1
192.168.10.0 and 192.168.20.0 and limit the rate to 512 kbit/s. Note that IP address-
based rate limiting is configured on LAN-side interfaces because NAT-enabled WAN-
side interfaces cannot identify intranet IP addresses. When configuring IP address-
based rate limiting on LAN-side interfaces, specify the source IP address in the
inbound direction to limit the upload rate, and specify the destination IP address in the
outbound direction to limit the download rate.

The procedure of configuring IP address-based rate limiting for other network
segments on GE0/0/2 is similar to the preceding procedure.
