These topics describe the fields on the dialog boxes used in Policy Manager.
The Application Service dialog box is opened when you click Add from the Application Services window.
Use the Application Service dialog box to add, view, or change the properties of an application service alias. You can use an application service alias in a policy to simplify the creation of policies that apply to a type of network traffic from one or more hosts.
| Field | Description |
|---|---|
The name of the application service alias. | |
The protocol used by the packets. | |
The host name or IP address of the server or subnet from which the packets originate. | |
The subnet mask that, combined with the IP address, signify the subnet from which the packets originate. | |
The port from which the packets originate. |
The Application Services dialog box opens when you do any of the following:
Click the Application Services button.
Use the Application Services dialog box to view the application service alias that you have defined. You can use an application service alias in a policy to simplify the creation of policies that apply to a type of network traffic from one or more hosts.
| Field | Description | Notes |
|---|---|---|
Table of application services | Each row in this table represents a separate application service, with these properties.
|
|
Click this button to add an alias to the list. |
| |
Click this button to change the properties of the selected alias. |
| |
Click this button to delete the selected alias. |
|
The Define Policy Filter dialog box is opened when you click New or Edit in the policy editor.
Use the Define Policy Filter dialog box to add, view, or change the properties of a policy filter element.
| Field | Description | Notes |
|---|---|---|
The protocol of the traffic you are identifying. |
| |
The TOS value of the packets you are identifying, if you are trying to filter on the TOS byte. | Select None if you want the filter to match any TOS value. | |
The IP precedence value of the packets you are identifying, if you are trying to filter on IP precedence. | Select None if you want the filter to match any IP precedence value. | |
The name of an application service (defined in the QoS database) that is the source of the packet, if you are trying to identify traffic that fits the defined alias.
| See "Working with Application Services Aliases" in Chapter 5 for more information. Leave this field blank if you are not filtering on an application service. | |
The name or IP address of a host that is the source of the packet, if you are trying to identify traffic based on host source.
| If you want to filter on more than one host source, create a host group (click Host Groups) and use the host group name in the Host Group field. | |
The name of a host group (defined in the QoS database) that contains the name of the host that is the source of the packet, if you are trying to identify traffic based on a set of host sources. If the packet comes from any of the hosts defined in the group, it matches this filter condition.
| See "Working with Host Groups" in Chapter 5 for more information. Leave this field blank if you are not filtering on host names contained in a host group. | |
The port that is the source of the packet, if you are trying to identify traffic based on port. For example, 80 is the typical port used by web traffic. | For a list of ports and their common uses, consult a comprehensive TCP/IP network architecture manual or Internet site. | |
Host Name (Destination) | The name or IP address of a host that is the destination of the packet, if you are trying to identify traffic based on host destination.
| If you want to filter on more than one host source, create a host group (click Host Groups) and use the host group name in the Host Group field. |
Host Group (Destination) | The name of a host group (defined in the QoS database) that contains the name of the host that is the destination of the packet, if you are trying to identify traffic based on a set of host destinations. If the packet goes to any of the hosts defined in the group, it matches this filter condition.
| See "Working with Host Groups" in Chapter 5 for more information. Leave this field blank if you are not filtering on host names contained in a host group. |
Port (Destination) | The port that is the destination of the packet, if you are trying to identify traffic based on port. For example, 80 is the typical port used by web traffic. | For a list of ports and their common uses, consult a comprehensive TCP/IP network architecture manual or internet site. |
The Device Group dialog box opens when you do one of the following:
Use the Device Group dialog box to create a device group, which is a group of interfaces to which you will apply identical policies. Device groups simplify the deployment of common policies. Also use this dialog box to view and change a device group's properties.
| Field | Description | Notes |
|---|---|---|
The name of the device group. |
| |
The minimum IOS software version used on the interfaces in the group. | You can only group interfaces that are running this version of IOS software or higher, because lower versions of the software might support different QoS capabilities. | |
The device model on which the interfaces reside. | Select ANY if you do not want to limit the group to a specific type of device. | |
The type of interfaces that the group contains. | Select ANY if you do not want to restrict the group to a specific type of interface. To use frame relay traffic shaping on frame relay interfaces, the group can only contain frame relay interfaces. Select Frame Relay to restrict the group to frame relay interfaces. | |
The QoS queuing property that should be assigned to the interfaces in the group. Select Defined By Interface if you do not want the device group to define the interface's QoS property, and you instead want to define the property on each interface. This is appropriate if you are using the device group mainly to apply common policy statements rather than common queuing properties. | See "How Does QoS Policy Manager Help Quality of Service?" in Chapter 1 for more information on queuing techniques. | |
The interfaces that belong to the device group. | These interfaces must be defined in a device folder in the Devices folder. | |
Click this button to add members to the group, or remove them from the group. | This button opens the Device Group Members Dialog Box. | |
Select this if you want to use the rate control features of frame relay traffic shaping on the interfaces in the group. | Available only if you select Frame Relay for Type. |
The Device Group Members dialog box opens when you do one of the following.
Use the Device Group Members dialog box to create a add or remove interfaces in a device group.
| Field | Description | Notes |
|---|---|---|
The interfaces defined for the devices in the group, minus the interfaces that already belong to a device group. You cannot place a single interface into more than one device group. | Use Ctrl+click to select more than one interface at a time, Shift+click to select a range of interfaces. | |
The interfaces that are already part of the device group. | Use Ctrl+click to select more than one interface at a time, Shift+click to select a range of interfaces. | |
Click this button to add the interfaces selected in Available Interfaces to the Group Members list. | These interfaces must already be defined in a device folder in the Devices folder for them to appear in this list. You cannot add an interface that is not already defined in the QoS database. | |
Click this button to remove the interfaces from the Group Members list. The interfaces are returned to the Available Interfaces list. | When you remove interfaces, the QoS property and associated policies (for example, for priority queuing and custom queuing interfaces) are copied to the interface. 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. If you click Yes or Yes to All, the policies are copied, meaning there is no change to the services provided by the interface. If you click No, the policies are not copied to the interface, changing the services provided by the interface. |
The DNS Host Name to IP Address Resolution dialog box opens when you do any of the following:
Use the DNS Host Name to IP Address Resolution dialog box to resolve host names used in host groups to their IP addresses.
| Field | Description | Notes |
|---|---|---|
The location within the QoS database that contains the host name, one of,
|
| |
The type of location within the QoS database, one of,
|
| |
The host name that needs to be resolved to an IP address. |
| |
The status of the host-name-to-IP-address resolution, one of,
| An arrow indicates the host name that is currently being resolved. | |
Click this button to skip the resolution of the host name currently being resolved. You might want to do this if the host name is taking a long time to resolve. |
| |
Click this button to filter the list so that correctly-resolved host names are not displayed. This helps you locate and resolution failures. | This button toggles with the Show All button. | |
Click this button to switch the list back to showing all hosts, including those whose IP addresses were successfully found. | This button toggles with the Show Unresolved button. | |
Click this button to stop the DNS resolution process. |
|
The Host Groups dialog box opens when you do any of the following:
Click the Host Groups button.
Use the Host Group dialog box to create, modify, or delete host groups. A host group is a collection of network hosts. You can use a host group in a policy to simplify the creation of policies that apply to a set of network hosts.
| Field | Description | Notes |
|---|---|---|
A list of available host groups. | To add a host group to this list, click in the empty box at the bottom of the list of host groups. If there is no empty box, click the Add button. | |
Click this button to duplicate the selected host group. |
| |
Click this button to delete the selected host group. | You cannot delete a host group if it is used in a policy. Remove all occurrences of the host group from your policies before deleting the group. | |
Click this button to view, add, or remove members of the selected host group. |
|
The Host Groups dialog box is opened when you,
Use the Host Group Members dialog box to add members to a host group or remove them from a host group.
| Field | Description | Notes |
|---|---|---|
The name or IP address of a network host. | To add a host to this list, click in the empty box at the bottom of the list of host names. If there is no empty box, click the Add button. | |

The Import Device dialog box is opened when you select Devices>Import. The title of the window includes the name of the file that contains the inventory displayed in the window.
Use the Import Devices dialog box to import devices into the QoS database from an inventory that you exported from either CiscoWorks2000 Resource Manager Essentials or Cisco Resource Manager (CRM). By importing devices from your existing inventory, you can quickly populate the QoS database, an avoid typing errors while entering each device manually.
While QoS Policy Manager is querying the devices in the inventory, you can edit the QoS database. Once the queries are finished, however, you must complete (or cancel) the importation process before returning to the main Policy Manager window.
| Field | Description | Notes |
|---|---|---|
The list of devices from the selected inventory, including IP address, device model, and IOS software version. | QoS Policy Manager queries the devices as it adds them to this list. This query can take a long time if there are a lot of devices. If a device cannot be queried, either because it is unavailable, or the SNMP query failed, this is indicated, and you cannot import the device. Devices that are supported and available are listed first. | |
The devices you select to import into the QoS Policy Manager database. | These devices are not added to the Devices folder until you click OK. If you click Cancel, the importation is aborted and the database is left unchanged. | |
>> | Click this button to add the selected devices to the devices to import list. |
|
<< | Click this button to remove the selected devices from the devices to import list. |
|
OK button | Click this button when you are finished selecting devices to import to the QoS database. | A message opens asking if you wish to detect the interfaces for the devices you want to import. The possible answers are; Yes, Yes All, No, No All and Cancel |
Cancel | Click this button to cancel importing any devices. | No devices will be added to the database.
|
Help | This button opens the Online help. |
|
Stop | Click this button to stops the querying of devices in the external database. | The query stops with last completed device. You can add all the valid Known Devices devices shown to your QoS database. |
The Interface Properties dialog box opens when you do one of the following:
Use the Interface Properties dialog box to view or change the interface's properties as defined in the QoS database. These properties do not affect the interface's configuration on the device.

| |
The IP address for the interface. |
| |
The subnet mask for the interface. |
| |
The transmission rate for the interface, in Kb/sec. For example, the rate of a standard |
| |
The type of interface, for example, ethernet. Select the interface type from the list of available types. | If you do not know the interface type, consult the documentation for the device. However, if the device is online, it is easier to obtain this information by closing the New Interface window and clicking Detect Interfaces on the New Device Dialog Box. | |
Select this if you want to use the rate control features of frame relay traffic shaping on the interface. | Available only if you select Frame Relay for Type. | |
The average bits per second rate for the virtual circuit, typically the minimum rate you are committed to provide on the circuit. | Available only if you select Frame Relay for Type and select Committed Information Rate. | |
The maximum bits per second rate for the virtual circuit. | Available only if you select Frame Relay for Type and select Committed Information Rate. | |
The amount of excess data, in bits, allowed through the circuit during the first interval once credit is built up on the connection. | Available only if you select Frame Relay for Type and select Committed Information Rate. | |
Select this field to have the interface reduce the traffic rate when it is notified that congestion is occurring at other interfaces along the path. | Available only if you select Frame Relay for Type and select Committed Information Rate. | |
The QoS queuing property that should be assigned to the interface. | See "How Does QoS Policy Manager Help Quality of Service?" in Chapter 1 for more information on queuing techniques. You cannot change this value if the property is defined by a device group that contains the interface. | |
The typical packet size that traverses the interface. QoS Policy Manager uses this value to calculate the byte size of the custom queues, the queues being a multiple of this packet size. You do not have to carefully calculate this value. Instead, pick a number that you feel would be an appropriate size for the smallest queue on the interfaces. | Available only if you select Custom Queuing for QoS property. | |
A factor used to determine the rate at which packets are dropped when traffic congestion occurs. The weight must be between 1 and 16. Use the default of 10 unless you determine a different factor is desirable. | Available only if you select Random Early Detect for QoS property. See the IOS software documentation for a detailed discussion of the random-detect weighting factor. |
The New Interface dialog box opens when you do one of the following:
Use the New Interface dialog box to manually define an interface for a device. However, it is easier to define a device's interfaces by clicking Detect Interfaces in the when adding the device (in the New Device dialog box), or by viewing the device properties (in the Device Properties dialog box, accessed by selecting the device and selecting Devices>Device>Properties).
You must manually define a device's interfaces if you are adding a device that is not connected to the network, either because it is not installed yet, or a network problem has made it temporarily unavailable.
