# Viewing interface groups

Enterprise Device Manager lets you display the interface groups.

Use this procedure to display interface groups.

## Procedure steps

1. From the navigation tree, double-click QoS.

2. From the QoS tree, double-click QoS Devices.

3. Select the Interface Groups tab.

## Variable definitions

The following table outlines the parameters of the Interface Groups tab.

Table 1. QoS Devices Interface Groups tab parameters
Variable | Value
--- | ---
Id | Displays a unique identifier of an interface group.
Role | Specifies the tag (group name) used to identify interfaces with the characteristics specified by the attributes of this class instance. These identifiers can be used within a number of classes to identify a physical set of interfaces to which policy rules and actions can apply.
Capabilities | Specifies a list of the interface capabilities used by the PDP or network manager to select the policies and configurations that can be pushed to the Policy Enforcement Point (PEP).
InterfaceClass | Specifies the type of traffic interfaces associated with the specified role combination.
StatsTrackingType | Specifies the type of statistics tracking. Options are aggregate, individual, or disabled.
StorageType | Displays storage type for this interface group: Volatile nonVolatile (default) readOnly

## Assigning ports to an interface group

Use this procedure to assign ports to an interface group.

### Procedure steps

1. From the navigation tree, double-click QoS.

2. From the QoS tree, double-click QoS Devices.

3. Select the Interface Groups tab.

4. Click Interface Assignment.

5. In the Group Assignment screen, click the port numbers to add to the interface group.

6. Click OK.

   | Note
   | If you add or delete many ports on a switch that is experiencing a heavy load the process can take a long time and the process can cause Enterprise Device Manager to time out.

For more information, see Table 1.

## Deleting ports from an interface group

Use this procedure to remove ports from an interface group.

### Procedure steps

1. From the navigation tree, double-click QoS.

2. From the QoS tree, double-click QoS Devices.

3. Select the Interface Groups tab.

4. Highlight the interface group from which to delete ports.

5. Click Interface Assignment.

   The Group Assignment screen opens.

6. Click the port numbers to delete from the interface group.

7. Click OK.

For more information, see Table 1.

## Adding interface groups

Use this procedure to add an interface group.

### Procedure steps

1. From the navigation tree, double-click QoS.

2. From the QoS tree, double-click QoS Devices.

3. Select the Interface Groups tab.

4. Click Insert.

   The Insert Interface Group screen opens.

5. Enter the desired ID number.

6. Enter the Role combination tag for this Interface Group.

7. Select the interface class desired for this interface group: trusted, nonTrusted, or unrestricted.

8. Click Insert.

For more information, see Table 1.

## Deleting interface groups

Use this procedure to delete an interface group.

### Procedure steps

1. From the navigation tree, double-click QoS.

2. From the QoS tree, double-click QoS Devices.

3. Select the Interface Groups tab.

4. Highlight the interface group to delete.

5. Click Delete.

   | Note
   | You cannot delete an interface group that a policy references. You must delete the policy first. Also, you cannot delete an interface group if you assigned ports to it.
