Provisioning Process for IP QoS

This chapter describes the steps required to provision IP QoS for a network using the Cisco IP Solution Center (ISC) graphical user interfaces.

This chapter describes how to set up IP QoS provisioning independent of VPN services. To set up QoS provisioning for VPN services, such as MPLS, L2VPN, and VPLS, see "Applying QoS Policies to VPN Services."

The chapter contains the following sections:

•IP QoS Process Model

•Launching the GUI

•Defining QoS Link Candidates

•Defining QoS Policies

•Deploying the QoS Service Request

IP QoS Process Model

The QoS process model in ISC is designed so that different types of users (for example, network administrators and service operators), can define different aspects of the QoS provisioning process.

The QoS provisioning process in ISC includes four operations:

•Defining the QoS Link Candidates—Identifying device interfaces for QoS provisioning

•Defining the QoS Policy—QoS policy based on service classes

•Defining the Link QoS Settings—QoS parameters that are sensitive to link bandwidth and Layer 2 encapsulation.

•Create and deploy the QoS service request—Create a container for the QoS policy and QoS link settings and apply these parameters to the devices in the service provider network.

Figure 5-1 depicts the ISC process flow for QoS provisioning.

Figure 5-1 Process Flow for IP QoS Provisioning

The rest of this chapter guides you through the QoS provisioning process using the ISC user interface. For each operation, a screen shot and example values for each entry field are provided. For reference, all examples in this chapter see the following network configuration (Figure 5-2).

Figure 5-2 Example of QoS Policy Deployment

Launching the GUI

The ISC user interface is designed so that different types of users can manage different aspects of the QoS provisioning process. For example:

•A network operator can use the Service Inventory tab to identify the device interfaces to be used for QoS provisioning. The device interfaces are called link end-points in the ISC GUI, and when selected, the device interface becomes a QoS Link Candidate to be used later in the QoS service request.

•A second network operator can use the Service Design tab to create service level and link level QoS polices. Use the Policy Manager hyperlink to create the service level QoS polices, and use the Link QoS Manager hyperlink to create the link level QoS polices.

•A service operator can use the Service Inventory tab to construct a QoS service request and deploy it in to the network.

Note To use the ISC user interface, you must be using Netscape Version 7.0 or later or Microsoft Internet Explorer, Version 6.0 or later.

To launch the ISC GUI:

Step 1 Open a web browser and enter the following URL to access the login screen (Figure 5-3):

http://<hostname or IP address of ISC Interface server>:8030/isc/login

Figure 5-3 ISC Login Screen

Step 2 Enter your User Name and Password and click Login. Contact the network administrator if you cannot log into the ISC GUI.

Step 3 If the login is successful, the ISC home window appears (Figure 5-4).

Figure 5-4 ISC Home Window

The home window provides access to the four main areas of operation in ISC; Service Inventory, Service Design, Monitoring, and Administration. For QoS provisioning, the two main operation areas are:

•Service Inventory—QoS provisioning in this area includes marking device interfaces for QoS provisioning. This operation is described in Defining QoS Link Candidates.

•Service Design—QoS provisioning in this area includes creating a QoS policy and defining link level QoS settings. These operations are described in Defining QoS Policies and Defining the Link Level QoS Policy.

Note The ISC home window you see depends on the licensed service packages you purchased.

Defining QoS Link Candidates

Before you can provision QoS commands on a network device, you must select the device interfaces as QoS candidates. For more information on determining which device interfaces might be congestion points and might benefit from QoS provisioning, see IP QoS Provisioning Strategies.

In the ISC GUI, the process of selecting device interfaces is called defining QoS link candidates.

For QoS provisioning, you must select both interfaces in the CPE-PE link. A typical device interface selection is as follows:

•For the CPE device:

–The provider-facing device interface is selected as the link endpoint

–The customer-facing LAN interface is selected for marking and rate limiting

Note Marking and rate limiting on the customer-facing LAN interface is optional.

•For the PE device:

–The customer-facing interface is marked as a link endpoint

The interfaces selected as link endpoints can be provisioned with QoS parameters such as policing, traffic shaping, congestion management, congestion avoidance, link efficiency, and CAR. You apply these parameters later in the provisioning process.

This section describes how to use the ISC GUI to select device interfaces as QoS candidates and includes:

•Selecting CPE Device Interfaces for QoS

•Selecting PE Device Interfaces for QoS

Selecting CPE Device Interfaces for QoS

Typically, the service provider supplies the list of devices and interfaces to be selected for QoS provisioning. This section describes how to select device interfaces for QoS.

To select interfaces in a CPE device for QoS:

Step 1 On the Service Inventory tab, click Inventory and Connection Manager. The left pane of the CPE devices window shows the TOC for this operation area and an icon in the right pane shows a graphical representation and short description. You can access an area of operation from either the TOC link or the icon link.

Step 2 From the TOC, click CPE Devices, which is located under Customers in the hierarchy pane. This displays the CPE Devices window and lists all CPE devices that can be edited (Figure 5-5).

Figure 5-5 CPE Devices List

Step 3 Select the check box next to the CPE device (for example, mlce1) and click Edit. The Edit CPE Device window appears (Figure 5-6). This window lists device details and all interfaces that might be candidates for QoS provisioning.

Figure 5-6 Identify CPE Device Interface as QoS Candidate

Step 4 Select the device interface for QoS provisioning. Select Link Endpoint from the QoS Candidate drop-down menu. This selects the interface on this CPE device as a link endpoint for QoS provisioning.

For information on the other entry fields in the Edit CPE Device window, see Cisco IP Solution Center Infrastructure Reference, 4.0.

Step 5 For the same CPE device, select the customer-facing LAN interface. Select Mark/Rate from the QoS Candidate menu (Figure 5-7). This selects the interface on this CPE device for marking and rate limiting.

Note Step 5 is optional, but recommended. If you bypass Step 5, the interface selected in Step 4 is used for marking and rate limiting.

Figure 5-7 Identify Customer-Facing LAN Interface as QoS Candidate

Step 6 Click Save. This saves the QoS interface information for the CPE device.

Step 7 Repeat Steps 1 through 4 for each CPE device that requires QoS provisioning. For each CPE device, specify the provider-facing interface as the QoS Candidate Link Endpoint, and specify the Mark/Rate parameter for the corresponding customer-facing LAN interface.

For the network example, mark CPE device enqosce51 with interface ATM1/0.52 defined as the QoS Candidate Link Endpoint, and FastEthernet 0/0 as the customer-facing LAN interface to be edited for Mark/Rate Limit.

Selecting PE Device Interfaces for QoS

You must also mark the PE device in the CPE-PE link for QoS provisioning. Typically, the PE device is marked for QoS parameters at the customer-facing interface.

Note If you have an untrusted CPE, one that is not managed or only partially managed by ISC, you can also re-mark and re-rate limit at the PE interface. Re-marking and re-rate limiting for PE devices is provisioned within the service class policy. See Creating the Service Level IP QoS Policy.

To mark a PE device:

Step 1 On the Service Inventory tab, click Inventory and Connection Manager.

Step 2 From the TOC, select PE Devices, which is located under Providers in the hierarchy pane. This displays the PE Devices window and lists all PE devices that can be edited (Figure 5-8).

Figure 5-8 PE Devices List

Step 3 Select the check box next to the PE device (for example, mlpe4) and click Edit. The Edit PE Device window appears (Figure 5-9). This window lists device details and all interfaces that might be candidates for QoS provisioning.

Figure 5-9 Identify PE Device Interface as QoS Candidate

Step 4 Select the interface (for example Ethernet1/0) for QoS provisioning. Select Link Endpoint from the QoS Candidate menu. This marks the interface on this PE device as a link endpoint for QoS provisioning.

Re-marking and re-rate limiting for PE devices is provisioned within the service class policy. See Creating the Service Level IP QoS Policy.

Step 5 Click Save. This saves the QoS interface information for the PE device.

Step 6 Repeat Steps 1 through 3 for each PE device that requires QoS provisioning. For each device, specify an interface as the QoS Candidate Link Endpoint.

For the network example, mark PE device enqosce5 with interface ATM1/0.52 defined as the QoS Candidate Link Endpoint.

Defining QoS Policies

A QoS service policy is divided into two policy categories; service level policies and link level policies. Most networks have a combination of both policy types.

These two parts of the ISC QoS policy are managed in different parts of the user interface.

•The Service level QoS policy is managed using Service Design > Policies.

•The Link level IP QoS policy is managed using Service Design > Link QoS Manager.

This section describes how to define a QoS policy using the ISC GUI and includes the following:

•Creating the Service Level IP QoS Policy

•Defining the Link Level QoS Policy

Creating the Service Level IP QoS Policy

The IP QoS policy is the set of rules or conditions that apply to packets as they come across each interface that has been assigned as a link endpoint. This set of rules is defined in a QoS service class.

A typical IP QoS policy consists of at least three service classes. ISC provides, by default, five different services class templates to use or modify.

•VoIP

•Routing Protocol

•Management

•Business-Data-1

•Best Effort

Select the service classes to use in the QoS policy and edit each one with the required parameters. All service classes require that you enter at least the bandwidth. You can also delete an unused service class, change the order of the service classes, or add another data service class, if needed.

The following sections describe how to create the service class portion of an IP QoS Policy using the ISC user interface. For detailed information on the entry fields for each service class parameter, see the "IP QoS Policy Parameters".

To create an IP QoS policy:

Step 1 On the Service Design tab, click Policy Manager (see Figure 5-10).

Figure 5-10 Policy Manager

The Policies window appears (Figure 5-11).

Figure 5-11 Create QoS Policy

The Policies window lists all policies that currently exist for the different ISC services. Use this window to make changes to an existing policy, or to delete an unwanted service policy.

Step 2 Click Create and select QoS Policy from the menu. The Qos Policy Creation window appears (see Figure 5-12).

Figure 5-12 Create QoS Policy

Step 3 Select IP QoS from the TOC at left. The Edit IP QoS Policy window (Figure 5-13) appears.

Figure 5-13 Edit IP QoS Policy

The Edit IP QoS Policy window lists the policy name, the customer or provider for this policy, and displays the five recommended default service classes. Use this window to select and edit the service classes to use in the QoS policy.

In addition to the service classes, you can re-mark or add re-rate limiting parameters to a PE device using the following check boxes.

•Mark MPLS Exp.—Use this parameter when provisioning QoS for a PE device that is in an MPLS network.

•Mark DSCP/Prec—Use this parameter to mark traffic based on the IP DSCP or precedence value.

•Rate Limit—Enable this parameter if the CPE is an untrusted device. An untrusted CPE is a device that is either not managed by ISC or only partially-managed by ISC.

Step 4 In the Edit IP QoS Policy window, enter the Policy Name. Select a policy name that is easily identified for your network. For example, if your customer is CustomerA, the policy name might be A-QoS.

Note We recommend that you use short customer names, policy names, and class-of-service names inside a QoS Policy. ISC combines the customer name and the QoS policy name to provision the policy-map command. Further, ISC combines the customer name, policy name, and class-of-service name to provision the class-map command. IOS has a limit of 40 characters for both policy-map and class-map command names. When the combination exceeds 40 characters, ISC attempts to truncate the combination and this might lead to service request deployment problems.

Step 5 Choose an Owner (Customer or Provider) for this QoS policy. Click the appropriate radio button and then Select.

Step 6 In the Customer (or Provider) for QoS Policy popup, select the customer (provider) and click Select (Figure 5-14).

Figure 5-14 Select Customer for QoS Policy

This identifies the customer for the QoS policy. You return to the Edit IP QoS Policy window.

The next step in defining the service level QoS policy is to edit the service classes. You can apply one or more service classes to the QoS policy. Edit the default service classes provided by ISC, delete the unwanted service classes, and add a data service class if necessary. A typical QoS policy consists of 3 service classes; VoIP, Management, and a data service class, such as Best Effort.

Step 7 To apply a service class to an IP QoS policy, select the class of service and click Edit CoS. The Edit Service Class window appears (Figure 5-15).

Figure 5-15 Edit Service Class—Routing Protocol

Step 8 From the Edit Service Class window, enter the QoS parameters, or service attributes, to apply to this service class and click OK.

Depending on the service class you are editing, you receive the appropriate window. For a detailed explanation of the entry fields for this service class and the windows for the other service classes, see Service Level IP QoS Parameters.

Step 9 Repeat Steps 7 and 8 for all services classes that you want applied to your QoS policy.

To change the processing order of the service classes, use the up and down arrow keys on the Edit IP QoS Policy window. The service class policies are applied to the network devices in the order they are presented on the Edit IP QoS Policy window.

Step 10 Add another service class, if required. See Adding a Data Service Class.

Step 11 Delete any service classes that you do not require for this QoS Policy. See Deleting a Service Class.

Step 12 After you edit and apply the required service classes, click Save to save the Qos Policy.

Note You must specify a bandwidth for each service class before you can save the QoS Policy.

When you save an IP QoS policy, a status information box is displayed on the bottom left of the ISC window. The following examples show the different status messages and user action required, to correct any problems.

a. Save succeeded. No further action is required. (Figure 5-16).

Figure 5-16 Save is Successful

b. Policy is in use and cannot be edited (Figure 5-17). To read the warning message, click More Info and take the necessary action to resolve the issue.

Figure 5-17 Edit QoS Policy with Warning

c. Save QoS policy failed (Figure 5-18). Click More Info to determine the source of the problem. You must fix all errors and resave before you can continue.

Figure 5-18 Save Unsuccessful

Note Not all devices and Cisco IOS platforms support all QoS parameter options. If you have specified an option for a device that is not supported, you don't receive the warning or error until after you deploy the service request.

Defining the Link Level QoS Policy

The second part of an ISC IP QoS policy is the link level policy, also called the link QoS setting. The link QoS setting describes the specific CPE-PE link QoS parameters to use.

The link QoS setting is a group of QoS parameters that are sensitive to link bandwidth and the CPE-PE link's layer 2 encapsulation type. Typically, a service provider requires several different link QoS settings, one for each link bandwidth.

Link QoS settings are associated with each link in the QoS Service Request. For each CPE-PE link in the QoS service request, you can have one corresponding link QoS setting.

Link QoS Manager

Use the Link QoS Manager to configure the link-specific QoS information.

Create the link QoS setting using the Link QoS Manager operation area of the ISC GUI. The Link QoS Manager allows you to create and manage the following link QoS settings:

•IP Link QoS Settings—Specify the QoS settings to apply to the link, such as aggregated traffic shaping and aggregated rate limiting. You also use the IP Link QoS Settings to specify Link Efficiency Settings, or LFI and interface-based aggregated rate limiting (also known as CAR).

Creating the Link QoS Setting

This section describes how to create a link QoS setting for a network.

To create the link QoS setting:

Step 1 On the Service Design tab, click Link QoS Manager (Figure 5-19).

Figure 5-19 Link QoS Manager

Step 2 The Link QoS Settings window appears (Figure 5-20).

Figure 5-20 Link QoS Settings

Step 3 The Link QoS Settings window displays the current link QoS settings available for QoS service requests, including the following information about each link QoS setting:

•Set Name—The name of your link QoS setting

•Owner—Customer or provider

•Type—IP Link Setting

•Encapsulation—Layer 2 encapsulation type.

•Bandwidth—Enter this value manually. For IP Link QoS Settings only.

You can select an existing link QoS setting or create a new one. For the network example, create a new IP Link QoS setting.

Step 4 Click Create. The IP Link QoS Settings Editor window appears (Figure 5-21).

Figure 5-21 IP Link QoS Settings Editor

Step 5 Enter the values in the IP Link QoS Settings Editor window. The entry fields are described in Table 5-1.

Table 5-1 IP Link QoS Settings Editor Entry Field

Entry Field

Description

Set Name

The name of the link QoS settings. Specify a name that describes the service offered by the settings. For example: Frame_64K_Gold; ATM_2Mb_Silver. The name Frame_64K_Gold indicates that this set should be used on a CPE-PE link of bandwidth 64kbps, whose layer-2 encapsulation is Frame Relay and to meet an SLA of Gold.

Owner (Customer or Provider)

Click Select to choose from a list of customers or providers.

Link Bandwidth

This is a required field. The link bandwidth specifies the maximum amount of bandwidth allocated for packets belonging to this link.

Aggregated Traffic Shaper

Applies traffic shaping QoS parameters to the device interface. Click Aggregated Traffic Shaper to set these parameters. Use this method instead of applying traffic shaping parameters with a service class. For more information on the parameters for aggregated traffic shaping, see Aggregated Traffic Shapers.

Link Efficiency

Click Link Efficiency to set these parameters. For more information on the link efficiency parameters, see Link Efficiency Settings.

Interface-based Aggregated Rate Limiter

This provides rate limiting for the traffic on a particular interface for the CPE-PE link. Click Interface-Based Aggregated Rate Limiter to set these parameters. For more information on the interface-based aggregated rate limiter parameters, see Interface-Based Aggregated Rate Limiters.

Step 6 Click OK.

Step 7 Repeat Steps 1 through 7 to add more IP Link QoS settings. Link QoS settings are associated with each CPE-PE link in the QoS Service Request. For each link in the QoS service request, you can optionally have one corresponding link QoS setting.

Step 8 Click Save to save the IP Link QoS settings.

Creating the QoS Service Request

After both the service level and the link level QoS polices are created, the final steps in the QoS provisioning process are to create and deploy a QoS service request.

A QoS service request contains one or more QoS links. A QoS link can contain two interfaces (CPE-PE link) or just one interface (CPE only or PE only). Each link can optionally be associated with a QoS link setting. A QoS policy can be associated with a QoS service request.

A QoS service request should:

•Contain a QoS policy

•Contain QoS links

All QoS links in the service request can optionally be associated with a link QoS setting

To apply QoS policies to network devices, you must deploy the QoS service request. When you deploy a QoS service request, ISC compares the device information in the Repository (the ISC database) with the current device configuration and generates a configlet.

This section describes how to create a QoS service request, independent of VPN services. To create a QoS service request for MPLS, L2VPN, or VPLS services, see "Applying QoS Policies to VPN Services".

To create an IP QoS service request:

Step 1 Select Service Inventory > Inventory and Connection Manager > Service Request (Figure 5-22).

Figure 5-22 Service Requests

The Service Request window appears. (Figure 5-23).

Figure 5-23 Service Requests List

The Service Requests window lists the current service requests.

Note For more information on service requests, see QoS Service Requests.

Step 2 From the Service Requests window, click Create and choose QoS.

Step 3 Select the customer for this service request and click OK (Figure 5-24).

Figure 5-24 Select Customer

The QoS Service Editor window appears (Figure 5-25).

Figure 5-25 QoS Service Editor

The QoS Service Editor window displays the following information about each QoS links:

•Link Op. Type—The link operation type for this CPE-PE link. For example, ADD means that you are adding this link to the service request. DELETE means that you are deleting this link from the service request.

•CE Link Endpoint—The CE device interface that was selected as a link endpoint QoS candidate.

•CE Templates—Add a set of commands (that ISC does not include) to the CE device by associating a template with the CE device. See Cisco IP Solution Center Infrastructure Reference, 4.0 for information on creating templates.

•PE Link Endpoint—The PE device interface identified as a link endpoint QoS candidate.

•PE Templates—Add a set of commands (that ISC does not include) to the PE device by associating a template with the PE device. See Cisco IP Solution Center Infrastructure Reference, 4.0 for information on creating templates.

•Link QoS Settings—Previously configured link QoS setting to use for this CPE-PE link.

•Bandwidth—This value automatically populates when you choose a link qos setting, or you can enter it manually.

Use the QoS Service Editor window to manage CPE-PE links, or to select MPLS service requests for IP QoS provisioning. You can also select link QoS settings for the CPE-PE links from this window.

Note If you are provisioning QoS for an MPLS, L2VPN, or VPLS service request, see "Applying QoS Policies to VPN Services.".

If you add CE and PE link endpoints, you get a CPE-PE QoS link. If you select link QoS settings for the CPE-PE link, you get link level QoS policy. Typically, a QoS service request has both a service level policy and link level QoS settings.

Step 4 Use the Policy drop-down menu to select a QoS policy to apply to this service request. For the network example, use CustomerA-QoS-Policy.

Step 5 To add a QoS link, click Add IP QoS Link.

The QoS Service Editor window displays two endpoints: CE Link Endpoint, and PE Link Endpoint. (Figure 5-26).

Figure 5-26 Select Link Endpoints

Step 6 Click Select Endpoint in the CE Link Endpoint field. The QoS Service Editor - Select CE window appears (Figure 5-27).

Figure 5-27 Select CE

This window lists all CE devices, including the Customer Site Name, CE device Name, and Device Type.

Step 7 Select a CE device and click Select QoS Interface. For example, select enqosce41.The QoS Service Editor - Select CE QoS Interface window appears (Figure 5-28).

Figure 5-28 Select CE QoS Interface

This window lists the CPE device interfaces identified during the Selecting CPE Device Interfaces for QoS operation, and includes the following information about the CPE device interfaces:

•Interface name—The name of the CPE device interface marked as a QoS candidate.

•Layer 2 (L2) Encapsulation—Layer 2 encapsulation type. For a list of supported encapsulation types, see Implementation Assumptions

•VC—ATM or Frame Relay virtual circuits. Choose from a list of circuit identifiers.

Step 8 Select the CE QoS interface and click OK. For example, select QoS Interface HSSI 1/0.41 with VC dlci41. You return to the QoS Service Editor window. The interface information for the CE link endpoint is listed.

Step 9 Next, select the corresponding PE link endpoint. From the QoS Service Editor window, Click Select Endpoint in the PE Link Endpoint field. The QoS Service Editor - Select PE Window appears (Figure 5-29).

Figure 5-29 Select PE

This window lists all PE devices, including the Provider Name, Provider Region Name, and PE device Name.

Step 10 Select a PE device and click Select QoS Interface. For example, select enqospe4. The QoS Service Editor - Select PE QoS Interface window appears (Figure 5-30).

Figure 5-30 Select PE QoS Interface

This window lists the PE device interfaces identified during the Selecting PE Device Interfaces for QoS operation, and includes the following information about the PE device interfaces:

•Interface name—The name of the PE device interface marked as a QoS candidate.

•Layer 2 (L2) Encapsulation—Layer 2 encapsulation type. For a list of supported encapsulation types, see Implementation Assumptions.

•VC—ATM or Frame Relay virtual circuits. Choose from a list of circuit identifiers.

Step 11 Select the PE QoS interface and click OK. For example, select QoS interface HSSI 2/1/0.41 with VC dlci41. You return to the QoS Service Editor window (Figure 5-31).

Figure 5-31 QoS Service Editor

The interface information for the PE link endpoint is listed.

Step 12 Repeat Steps 1-11 to add more CE and PE link endpoints.

Step 13 To add a link level QoS policy to this link, click None in the Link QoS Settings field or select the link with the check box in the second column and click Select Link Param. The Select Link QoS Settings window appears (Figure 5-32).

Figure 5-32 Select Link QoS Settings

This window lists all set names (link QoS settings) created during the Defining the Link Level QoS Policy operation.

Step 14 Select the link QoS setting (set name) to apply to this CPE-PE link. For example, select FRTS1, and click OK.

When you have finished adding all CPE and PE Link Endpoints, the service request creation process is complete.

Step 15 Save the QoS service request by clicking Save (Figure 5-33).

Figure 5-33 Save QoS Service Request

This saves the QoS service request parameters to the ISC Repository. The ISC-generated configlet is downloaded to the network device when the service request is deployed. See the following section.

For more information on the ISC Repository, see Cisco IP Solution Center Infrastructure Reference, 4.0.

Deploying the QoS Service Request

To apply QoS policies to network devices, you must deploy the QoS service request. When you deploy a QoS service request, ISC generates a configlet to download to each device.

When the configlets are generated, the QoS service request enters the Pending state. When the configlets are downloaded to all the devices in the service request, the QoS service request enters the Deployed state.

To deploy a QoS service request:

Step 1 Select Service Inventory > Inventory and Collection Manager > Service Requests. The Service Requests window appears (Figure 5-34).

Figure 5-34 Deploy QoS Service Request

This window shows all active service requests for this user name and the following service request information: JobID, State, Type, Operation Type, Creator, Customer Name, Policy Name, Last Modified Date, and the Description.

From the Service Request window, you can Create, view the Details, Edit, Deploy, Decommission, and Purge an active service request.

Step 2 Create and schedule a deployment task by clicking the Deploy button. Select Deploy from the menu.

Tip Force Deploy generates configlets for a service request that is already in the Deployed state and downloads it to the network devices. Use Force Deploy when a device configuration is lost or when you replace or change equipment.

ISC generates the QoS configlet and downloads it to the network device.

To see if a QoS service request is successfully deployed, check the State field on the Service Request window.

Note For more information on QoS service requests, see QoS Service Requests.
