Configure Classifier Map Services

About this task

To map a traffic category to a QoS class, select the specified tab, and then define the traffic settings described in the following procedures.

Note

Be sure to enable all the categorization methods you want devices to use when assigning incoming traffic to various QoS classes. A network policy can reference just one classifier map.

Procedure

Select either Network Services or Application Services.
Extreme Network devices can map incoming traffic to classes based on the network or application service type defined in the classifier map.
Select one or more services (up to a maximum of 100) that you want to map to a class.
Select Save.
Choose Select... and filter services by typing part or all of a service name in the Filter field.
As an alternative, you can select services individually.
Select Save.
Select a QoS class to which you want to map the selected services or applications.
For the action, choose Permit or Deny.
The permit and deny actions in a QoS policy enable devices to enforce a simple stateless firewall policy that inspects packets individually, instead of within the context of an ongoing session. Because a stateless firewall configured to permit outgoing requests does not associate the corresponding incoming responses, you must configure a separate policy to permit the return traffic. A stateful firewall uses an internal table to associate corresponding outgoing and incoming traffic.
Enable Logging to permit devices to log traffic that matches the service-to-Extreme Networks class mapping.
Devices log traffic whether the action is permit or deny. The main reason to log traffic is to see if the devices are receiving expected or unexpected types of traffic when you debug connectivity issues. You can see these log entries in the even log using the
```
show logging buffered
```
command, or you can configure the device to send event logs to a syslog server and view them there.
Select the add icon to configure additional QoS class definitions.
To modify any classifier map, select the name of the map and modify everything except the map name, then select Save. To remove one or more classifier maps, select the check box for the map or maps you want to remove and then select the trash icon.
Note
You cannot remove a classifier map if one or more network policies currently reference it. You must first edit the network policies so that they no longer reference the map you want to remove.
