The following is the experiment process.

Access-list 102 permit ip 192.168.1.0 0.0.255 any

Access-list 102 permit ip any 192.168.1.0 0.0.255

Step 2: define class-map and call the ACL in step 1

Class-map match-all 102

Match access-group 102

Step 3: Define policy-map, call class-map, and limit the speed

Policy-map 102

Step 4: Apply policy-map to the interface
