Configuring the classifier policies example

These steps are part of the classifier policies configuration example.

On the 6400 Switch Series, interface identification differs.

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
