These topics describe tasks for working with devices and their interfaces.
The devices managed by QoS Policy Manager are typically routers. These devices must run IOS software that supports QoS capabilities.
You must add a device to the QoS database before you can manage the interfaces on the device.
Obtain this information for each device you are adding.
If the device is offline, you also need this information.
The New Device window is displayed.
Step 2 Fill in the New Device window (see "New Device Dialog Box" in Appendix B for more information). At minimum, you must supply this information.
Step 3 On the New Device window, click Verify Device Info. This obtains the IOS software version information from the device, as well as the device model.
If the device is not online, fill in the Vendor, Software Version, and Device Model fields manually.
Step 4 On the New Device window, click Detect Interfaces. This closes the New Device window and obtains the list of interfaces that are available on the device.
QoS Policy Manager creates a folder for the device in the tree view using the IP address of the device. The device interfaces are included as members of this folder.
You can add several devices at once by importing them from a device inventory created using CiscoWorks2000 Resource Manager Essentials or Cisco Resource Manager (CRM).
Export a device inventory using CiscoWorks2000 Resource Manager Essentials or Cisco Resource Manager (CRM).
(a). QoS Policy Manager opens a browsing window (Open).
(b). Select the directory that contains the device inventory you want to use.
Step 2 Select the file that contains the device inventory and click OK.
(a). QoS Policy Manager opens the Import Devices window, and begins querying the devices in the inventory.
(b). You can click Stop at any time. The QoS Policy Manager stops querying the devices, and displays only those already queried already.
(c). You can continue using Policy Manager while QoS Policy Manager queries the devices.
(d). When QoS Policy Manager is finished determining the state of each device, you are returned to the Import Devices window.
Step 3 Select the devices you wish to add to the QoS database.
(a). Click once on the device you wish to add to the QoS database in the "Known Devices" list on the left side of the window.
(b). Click >>. The device is transferred to the "Devices to import to QoS database" on the right side of the window.
Step 4 When you are satisfied with the list of devices to import, click OK.
Step 5 A Detect Interface message asks if you wish to detect the interfaces for the devices. The possible answers are
Step 6 When you are satisfied with the selection and detection of the device interfaces, click OK. You are returned to the QoS Manager window.
You can view a device's properties, and change them if required.
QoS Policy Manager opens the Device Properties window.
If you want to change the device properties, make your changes in the window and click OK.
If you do not want to manage QoS on a device, you can remove it from the QoS database.
If any of the device interfaces belong to a device group, a warning message appears and prompts you to confirm the deletion.
If you confirm the deletion, QoS Policy Manager deletes the device, its interfaces, all associated policy statements, and device group memberships for the device.
You can view the IOS software configuration for a device from within QoS Policy Manager.
Step 2 Select Devices>Device>View Configuration, or right-click and select View Device Configuration.
Step 3 QoS Policy Manager opens a window with the IOS software configuration as defined on the device. See the IOS software documentation for information on how to read the configuration.
You can start the Microsoft Telnet program from within QoS Policy Manager.
QoS Policy Manager starts the Microsoft Telnet program. See the online help for Telnet for information on how to use the program.
The interfaces on a device carry the network traffic. You must add the interfaces on which you want to define QoS policies to the QoS database.
If a device is already defined in the QoS database, you can add its interfaces to the database.
If the device is not yet defined in the QoS database, see "Adding a Device." Once you have defined a device, you can have QoS Policy Manager query the device and add its interfaces to the QoS database (the automated procedure), or you can manually define the interfaces.
It is easiest to have QoS Policy Manager obtain the interface information from the device. However, the device must be online in order for QoS Policy Manager to obtain the information. If you are adding interfaces for an offline device, you must use the manual procedure.
QoS Policy Manager opens the Device Properties window.
Step 2 Click Detect Interfaces.
QoS Policy Manager obtains interface information from the device and adds the interfaces to the tree view in the device's folder.
Step 2 Select Devices>Interface>New, or right-click and select New Interface.
QoS Policy Manager opens the New Interface window.
Step 3 Enter in the interface properties. See "New Interface Dialog Box" in Appendix B for more information.
You can view an interface's properties, and change them if required.
QoS Policy Manager opens the Interface Properties window.
If you want to change the interface properties, make your changes in the window and click OK.
If you do not want to manage QoS on an interface, but you still want to manage QoS on other interfaces on the device, you can remove the interface from the QoS database.
If the interface belongs to a device group, you are warned and given a chance to confirm the deletion.
If you confirm the deletion, QoS Policy Manager deletes the interfaces, all associated policy statements, and device group memberships for the interface.
A device group is a group of interfaces that reside on one or more device. You can use device groups to simplify the deployment of your policies, because you can write a policy for the group instead of for each interface separately.
There are two main reasons to group interfaces.
These sections describe device groups in more detail.
You can only combine interfaces in a group if the interfaces are using the same, or higher, version of IOS software. This ensures that you do not create a policy on the device group that is not supported on one or more interfaces in the group.
When you create a device group, you must state the minimum IOS software version that should be allowed in the device group. QoS Policy Manager only lets you add interfaces to the group that use this IOS software version or higher.
Table 6-1 shows the compatibility matrix for IOS software used by QoS Policy Manager.

Create a device group when you want to use identical policies for more than one interface.
Identify the interfaces that you want to treat as a group.
QoS Policy Manager opens the Device Group window.
Step 2 Fill in the fields in the Device Group window (see "Device Group Dialog Box" in Appendix B for more information).
If you are creating a device group to define a common QoS property, set the desired property in the QoS property field. Otherwise, set the QoS property to Defined By Interface.
Step 3 In the Device Group window, click Add/Remove in the Group Members group.
QoS Policy Manager opens the Device Group Members window.
Step 4 In the Device Group Members window, select the desired interfaces in the Available Interfaces list and click >>.
The Available Interfaces list only includes interfaces that
Click OK when you have finished adding interfaces. QoS Policy Manager returns you to the Device Groups window.
Step 5 Click OK in the Device Groups window.
QoS Policy Manager adds the device group to the Device Groups folder in the tree view. You can now select the group and add policies to it.
Once you have defined a device group, you can add members to the group, or remove them from the group.
If you want to add an interface to a device group, and the interface is currently running a lower version of IOS software than the one defined for the group, you must upgrade the IOS software on the device before you can add the interface to the group.
QoS Policy Manager opens the Device Group Members window.
Step 2 If you are adding members, select the desired members in the Available Interfaces list and click >>. This list only contains interfaces that satisfy the device group characteristics and that do not already belong to a group.
Step 3 If you are removing members, select the members in the Group Members list and click <<.
Modify a device group when you want to add or remove interfaces, or change other parameters for the group.
You can only change these properties of a device group.
If you want to change the Software Version or Device Model properties, you must create a new device group. Changing these properties might invalidate policies that you have defined and distributed to the members of the group.
QoS Policy Manager opens the Device Group window.
Step 2 Make the desired changes to the device group properties (see "Device Group Dialog Box" in Appendix B for more information).
Delete a device group when you no longer want to treat the group of interfaces as a group. However, if you only want to remove some of the members of the group, you do not need to delete the group. See "Adding or Removing Device Group Members" for more information.
Step 2 Select Devices>Device Group>Delete, or right-click and select Delete Device Group.
QoS Policy Manager asks you to confirm the deletion.
When you delete a device group, the group's QoS property and associated policies (for example, policies that create priority or custom queues) are copied to the interfaces that were members of the device group. You are asked whether other policies defined on the group, such as coloring or shaping policies, should be copied to interfaces that you are removing.
When you create a device group, you specify the minimum IOS software version allowed for members of the group. Because this is a minimum version level, you can upgrade your devices without affecting QoS Policy Manager's deployment of policies to the devices.
However, if you downgrade the IOS software version on a member of a group to a version below the minimum version, you can encounter problems. If your policies, or QoS property, for the interface is incompatible with the QoS capabilities of the IOS software version, you will see errors in Distribution Manager when you try to deploy policies to the device group.
If you need to downgrade the IOS software version on a device, make sure you remove the device interfaces from device groups that require a higher version of the software.
