The Cisco 12000 GSR uses both terminating Permanent Virtual Circuits (PVCs) and Switched Virtual Circuits (SVCs). A PVC is modeled in CGM as an object that is deployed beneath an interface. The interface acts as the endpoint. An SVC is modeled in CGM as an object that is deployed beneath an interface, but it has two endpoints. The remote endpoint can either be a non-CEMF endpoint (which means it is outside Cisco EMF) or a CEMF endpoint (which means it is within Cisco EMF).

SVCs are similar to PVCs in setup; however, they function differently. The PVC is always operating and is always up. On the other hand, the SVC shuts down when it is not in use. It does not cease to exist, but only goes down until traffic occurs, then it re-establishes again.

Overall Process of Creating ATM Connections

To create a PVC or SVC, follow these instructions:

1. Upload any existing ATM connections and QoS (Quality of Service) profiles, if required (for details, refer to "Uploading PVCs and ATM QoS Profiles.")

2. Create an ATM QoS profile, if required (for details, refer to "Creating ATM QoS Profiles.")

3. Deploy (create) the PVC or SVC, using the Deployment Wizard (for details, refer to "Deploying a PVC" or "Deploying an SVC.") This process creates the PVC or SVC in Cisco EMF only; it does not create the connection on the device.

4. Apply the QoS profile to the PVC or SVC (for details, refer to "Applying an ATM QoS Profile to an ATM Connection.")

5. Configure the fields for the PVC or SVC, including layer 2 and 3 information (for details, refer to "PVC Configuration" or "SVC Configuration.") You can then create the connection on the device, which automatically commissions the PVC or SVC.

Uploading PVCs and ATM QoS Profiles

When you upload PVCs, any corresponding ATM QoS profiles are uploaded as well. PVCs are discovered and placed into the normal state, so that management of these connections begins automatically. Once these connections and/or profiles are uploaded, you can view and adjust them in CGM.

Before you can upload any connections or profiles, make sure your telnet passwords are correctly configured in CGM (for details, refer to "Entering or Changing Username and Passwords.")

The Uploading PVCs and ATM QoS Profiles section covers the following areas:

•Viewing the ATM Connection Upload Window

•ATM Configuration Upload Window—Detailed Description

Viewing the ATM Connection Upload Window

To open the ATM Connection Upload window, proceed as follows;

---

Step 1 Right-click a chassis object, then choose CGM Management>Logical>ATM>VCL Management> Upload. The ATM Connection Upload window appears.

Figure 11-1 ATM Connection Upload Window

Step 2 The chassis you selected appears at left. Click Upload, and all ATM connections and ATM QoS profiles currently configured on the selected device are uploaded into CGM.

Uploaded ATM connections and ATM QoS profiles are named according to the following formats:

ATM connections—PVC - ("VCL_VPI.VCI", for example VCL_10.20.)

ATM QoS Profiles—QoSProfile_(assigned number)

---

---

Note Only PVC upload will be available no SVC upload is available.

---

ATM Configuration Upload Window—Detailed Description

The ATM Connection Upload window contains a single Connection Upload tab.

Connection Upload Tab

The Connection Upload tab contains a single Upload area.

Upload

Upload Progress—Current progress of the upload operation.

Upload Status—Upload status messages for the current upload operation.

Upload—Click Upload to initiate the upload of the ATM connections and QoS profiles from the selected chassis.

Creating ATM QoS Profiles

The ATM QoS Profile Configuration window allows you to create and save ATM QoS profiles. ATM QoS profiles are stored in CGM and the associated fields are created on the device when the connection (PVC or SVC) is created.

---

Note Once you have created an ATM QoS profile, you can only edit that profile if it is not being used. If any connections are using that profile, you cannot alter the profile. You can view which specific connections are using a certain profile by running a Cisco EMF query against the profile name (for details, refer to the Cisco EMF User Guide.)

---

The Creating ATM QoS Profiles section covers the following areas:

•Viewing the ATM QoS Profiles Configuration Window

•Deploying a PVC

•Editing or Deleting an ATM QoS Profile

Viewing the ATM QoS Profiles Configuration Window

To open the ATM QoS Profiles Configuration window, proceed as follows:

---

Step 1 Right-click on an interface, then choose CGM Management>Logical>ATM>QoS>Profile. The ATM QoS Profiles window appears.

Figure 11-2 ATM QoS Profiles Window—Profile Tab

The ATM QoS Profiles window contains two tabs: Profile and RxTx Parameters. The Profile tab appears by default when you open the ATM QoS Profiles window.

Step 2 Create a profile by typing information in the required fields, or by copying the parameters from an existing profile.

•To create a new profile, proceed as follows:

–Click Create Profile.

–Type in the new profile name, then click Ok.

–Fill in the required fields in the Profile tab and in the RxTx Parameters tab (only the Tx or transmit area is applicable).

–Click the Save icon to save your changes.

•To create a profile based on an existing profile, click the profile you want to model from the profile list box at left.

–Click Create Profile and type a name for the new profile.

–Choose the newly created profile from the list box at left.

–Modify the fields in the Profile tab and in the RxTx Parameters tab (only the Tx or transmit area is applicable) if necessary.

–Click the Save icon to save your changes.

---

Editing or Deleting an ATM QoS Profile

An existing ATM QoS profile can only be edited or deleted if it is not currently being applied to any interfaces. Once you have applied a QoS profile to an interface, you cannot edit or delete it unless you remove it from the interface. If that QoS profile is being used by any other interfaces, you will still not be able to edit or delete the QoS profile. If you want to view the connections that are using a specific profile, run a Cisco EMF query against the profile name (for details, refer to the Cisco EMF User Guide.) Once you have removed a QoS profile from all interfaces, you can proceed to edit the fields within the ATM QoS Profiles Configuration window or delete the selected QoS profile.

To delete an ATM QoS Profile, proceed as follows:

•In the ATM QoS Profiles Configuration window, in the list box at left, right-click on the profile name you want to delete

•Go to Deployment>Delete Objects. The delete wizard appears.

•Click Finish to delete the selected object. A message appears, confirming successful deletion. Note that deletion fails if the QoS profile is currently being used.

ATM QoS Profiles Configuration Window—Detailed Description

The ATM QoS Profiles Configuration window contains two tabs: Profile and RxTx Parameters.

Profile Tab

The Profile tab contains the following fields:

Profile Type—Enter the type of profile you are creating. This is the level of service, for example, gold service or bronze service.

Profile Description—Enter a description for this profile. Use the horizontal and vertical scroll tools to view text not displayed in the window.

RxTx Parameters Tab

It is possible to select a Service Category that is not supported by the GSR, such as ubr. However, this will be detected when an attempt is made to create the connection on the device & the operator informed. Also, Transmit & Receive are applicable to SVCs. Only Transmit is applicable for PVCs.

The RxTx Parameters tab contains the Receive and Transmit Parameters for the selected ATM QoS profile. Note that only the Transmit (Tx) parameters are applicable to QoS profiles.

Figure 11-3 ATM QoS Profiles Configuration Window—RxTx Parameters Tab

The RxTx Parameters tab has three areas:

•Category

•Receive Parameters (not applicable for CGM)

•Transmit Parameters

Category

The Category area contains one field, as follows:

QoS—Service category of the selected QoS profile.

Transmit Parameters

The Transmit Parameters area contains the following fields:

CLP (Cell Loss Priority)—Determines the probability of a cell being dropped if the network becomes congested. Cells with CLP = 0 are insured traffic, which is unlikely to be dropped. Cells with CLP = 1 are best-effort traffic, which might be dropped in congested conditions in order to free up resources to handle insured traffic.

SCR (Sustainable Cell Rate)—Maximum sustained-cell-rate (scr) traffic parameter that is allowed for connections.

PCR (Peak Cell Rate)—Maximum transmitting rate of cells.

MCR (Minimum Cell Rate)—Lowest acceptable transmitting rate (specified in cells per second) for connections.

MBS (Maximum Burst Cell Size)—Maximum burst cell size permitted by cells of connections.

CDVT (Cell Delay Variation Tolerance)—Cell delay variation estimated to be experienced by cells of connections.

Deploying a PVC

---

Tips PVC and VCL are interchangeable terms in CGM.

---

You can deploy a PVC either under a main interface or a subinterface. To deploy a PVC on a main interface or a subinterface, proceed as follows:

---

Step 1 Right-click on a selected line card or physical interface, then choose Deployment>CGM>Logical> ATM>PVC. The Deployment Wizard appears.

Figure 11-4 Deployment Wizard—Templates

Step 2 Choose the template you want to use, either: Cisco PVC under ATM EndPoint or Cisco PVC under ATM EndPoint on Sub Interface, and select either auto named or user named (for details on auto vs. user named, refer to "Deploying Modules.") Make sure your selection is highlighted in black before clicking Forward.

Figure 11-5 Deployment Wizard—Object Parameters

Step 3 Enter the number of Cisco PVCs (VCLs) you want to create.

Step 4 Enter a unique name (prefix and suffix) for the VCL (Cisco PVC by default).

Step 5 Enter the PVC Object Number. If you are creating multiple PVCs, you need to provide a start number which will be included in the PVC name. For example, if you are creating three PVCs, and you specify a start number of one, the PVCs will be numbered one, two, and three. If you deploy more PVCs in the future on this same interface, remember to not duplicate this starting number. For example, if you already have three PVCs deployed on this interface and they are numbered one, two, and three, and you now want to deploy six more, begin your PVC object number at four, where you left off previously. The six new PVCs will be numbered four, five, six, seven, eight, and nine. (for details on auto-named deployment, refer to "Deploying Modules.")

Step 6 Click Forward to proceed.

Disconnecting a PVC disconnects the connection entirely from the device.

Figure 11-16   ATM VCL Configuration Window—Layer 3 Configuration Tab

•Make sure that the Cisco VCL (PVC) you want to connect or disconnect is selected in the list box at left.

•Click the Connect or Disconnect button in the Action area.

Decommissioning or Re-Commissioning a PVC

When you connect a PVC, it is automatically commissioned as well. Decommissioning does not disconnect the PVC; it simply stops active management on the connection.

To decommission a connected PVC:

•Make sure that the PVC you want to decommission is selected in the list boxes at left. You can select multiple PVCs if desired.

•Click the Decommission button in the Action area.

Once you have decommissioned a connected PVC, you might want to commission it again, to re-establish management on the connection. To re-commission a PVC, simply click Connect and the connection is commissioned.
