Configuring the classifier policies example

These steps are part of the classifier policies configuration example.

Procedure

Configure Switch A.

Create traffic classes named SERVER_TRAFFIC and HOST_A_TRAFFIC for matching the packets from the server and Host A:

switch# configure
switch(config)# class ip SERVER_TRAFFIC
switch(config-class-ip)# match any 1.1.1.1 any 
switch(config-class-ip)# exit
switch(config)# class ip HOST_A_TRAFFIC
switch(config-class-ip)# match any 1.1.1.2 any 
switch(config-class-ip)# exit

Create a classifier policy named RATE_LIMIT_POLICY:
```
switch(config)# policy RATE_LIMIT_POLICY 
```
Configure the policy RATE_LIMIT_POLICY, so that 102,400 kbps of traffic, matching the class SERVER_TRAFFIC, is forwarded and the excess is dropped:
```
switch(config-policy)# class ip SERVER_TRAFFIC action cir kbps 102400 cbs 0 exceed drop
```
Configure the policy RATE_LIMIT_POLICY so that 25,600 kbps of traffic, matching the class HOST_A_TRAFFIC, is forwarded and the excess is dropped:
```
switch(config-policy)# class ip HOST_A_TRAFFIC action cir kbps 25600 cbs 0 exceed drop
switch(config-policy)# exit
```

Apply RATE_LIMIT_POLICY to interface 1/1/1 for the inbound traffic:

switch(config)# int 1/1/1
switch(config-if)# apply policy RATE_LIMIT_POLICY in 
switch(config-if)# exit

To view the configuration with the RATE_LIMIT_POLICY applied:

switch# show running-config
Current configuration:
!
...
class ip SERVER_TRAFFIC
    10 match any 1.1.1.1 any
class ip HOST_A_TRAFFIC
    10 match any 1.1.1.2 any
policy RATE_LIMIT_POLICY
    10 class ip SERVER_TRAFFIC action cir kbps 102400 cbs 0 exceed drop 
    20 class ip HOST_A_TRAFFIC action cir kbps 25600 cbs 0 exceed drop 
interface 1/1/1 
    apply policy RATE_LIMIT_POLICY in

Configure Switch B.

Create a traffic class named HTTP_TRAFFIC and configure it to match traffic to port 80:

switch(config)# class ip HTTP_TRAFFIC 
switch(config-class-ip)# match tcp any any eq 80  
switch(config-class-ip)# exit

Create a classifier policy named RATE_LIMIT_HTTP:
```
switch(config)# policy RATE_LIMIT_HTTP 
```
Configure the policy RATE_LIMIT_HTTP so that 204,800 kbps of traffic, matching the class HTTP_TRAFFIC, is forwarded and the excess is dropped:
```
switch(config-policy)# class ip HTTP_TRAFFIC action cir kbps 204800 cbs 0 exceed drop
switch(config-policy)# exit
```

Apply RATE_LIMIT_HTTP to interface 1/1/1 for inbound traffic:

switch(config)# int 1/1/1 
switch(config-if)# apply policy RATE_LIMIT_HTTP in 
switch(config-if)# exit

Show the running configuration with RATE_LIMIT_HTTP applied:

switch# show running-config 
Current configuration:
!
...
class ip HTTP_TRAFFIC
    10 match tcp any any eq 80
policy RATE_LIMIT_HTTP
    10 class ip HTTP_TRAFFIC action cir kbps 204800 cbs 0 exceed drop 
interface 1/1/1 
    apply policy RATE_LIMIT_HTTP in
