Configuring a class map using an ACL

Enter global configuration mode.
```
device# configure terminal
```
Create an IP access list to define the traffic.
1. Create and name a standard IP access list and enter IP ACL configuration mode.
```
device(config)# ip access-list standard ip_acl
```
2. Allow traffic from a specific IP address.
```
device(conf-ipacl-std)# permit host 10.10.10.0
```
3. Exit IP ACL configuration mode to global configuration mode.
```
device(conf-ipacl-std)# exit
```
For details on creating access lists, refer to the Extreme SLX-OS Security Configuration Guide for the device.

Verify the IP ACL.

device(config)# do show running-config | include ip_acl
ip access-list standard ip_acl

Create and name a class map.
```
device(config)# class-map class_1
```

Provide match criteria for the class.

device(config-classmap)# match access-group ip_acl

Return to privileged EXEC mode.
```
device(config-classmap)# end
```

Verify the class configuration.

device# show running-config | include class
...
class-map cee
class-map class_1
class-map default

Save the running-config file to the startup-config file.
```
device# copy running-config startup-config
```

Class map using an ACL configuration example

device# configure terminal
device(config)# ip access-list standard IP_acl
device(conf-ipacl-std)# permit host 10.10.10.0
device(conf-ipacl-std)# exit
device(config)# do show running-config | include ip_acl
device(config)# class-map class_1
device(config-classmap)# match access-group ip_acl
device(config-classmap)# end
device# show running-config | include class
device# copy running-config startup-config
