Cisco7200/7400 chassis use both terminating Permanent Virtual Circuits (PVCs) and Switched Virtual Circuits (SVCs). A PVC is modeled in Cisco 7200/7400 Series Manager as an object that is deployed beneath an interface. The interface acts as the endpoint. An SVC is modeled in Cisco 7200/7400 Series Manager as an object that is deployed beneath an interface, but it has two endpoints. The remote endpoint can be either a non-CEMF endpoint (outside CEMF) or a CEMF endpoint (within CEMF).
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.
This chapter contains the following information:
1. Upload any existing ATM connections and Quality of Service (QoS) profiles, if required (for details, see the "Uploading PVCs and ATM QoS Profiles" section).
2. Create an ATM QoS profile, if required (for details, see the "Creating ATM QoS Profiles" section).
3. Deploy (create) the PVC or SVC, using the Deployment Wizard (for details, see the "Deploying a PVC" section or the "Deploying an SVC" section). This process creates the PVC or SVC in Cisco 7200/7400 Series Manager only; it does not create the connection on the device.
4. Apply the QoS profile to the PVC or SVC (for details, see the "Applying an ATM QoS Profile to an ATM Connection" section).
5. Configure the fields for the PVC or SVC, including layer 2 and 3 information (for details, see the "PVC Configuration" section or the "SVC Configuration" section). You can then create the connection on the device, which automatically commissions the PVC or SVC.
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 profiles are uploaded, you can view and adjust them in Cisco 7200/7400 Series Manager.
Before you upload any connections or profiles, make sure your telnet passwords are correctly configured in Cisco 7200/7400 Series Manager (for details, see the "Entering or Changing Username and Passwords" section.)
This section covers the following topics:
To open the ATM Connection Upload window:
Step 2 The chassis you selected appears on the left side of the window. Click Upload, and all ATM connections and ATM QoS profiles currently configured on the selected device are uploaded into CERM.
Uploaded ATM connections and ATM QoS profiles are named according to the following formats:
The ATM Connection Upload window contains a single tab: Connection Upload.
The Connection Upload tab contains a single area: Upload.
The Upload area displays the following fields:
The ATM QoS Profile Configuration window allows you to create and save ATM QoS profiles. ATM QoS profiles are stored in Cisco 7200/7400 Series Manager, 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 edit that profile only if it is not being used. If any connections are using that profile, you cannot alter it. You can view which specific connections are using a certain profile by running a CEMF query against the profile name (for details, refer to the Cisco Element Management Framework User Guide). |
This section covers the following topics:
To open the ATM QoS Profiles Configuration window:
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.
b. Enter the new profile name, then click OK.
c. Fill in the required fields in the Profile tab and in the RxTx Parameters tab (only the Tx, or transmit area, is applicable).
a. Click Create Profile and enter a name for the new profile.
b. Choose the newly created profile from the list box on the left side of the window.
c. Modify the fields in the Profile tab and the RxTx Parameters tab (only the Tx, or transmit, area is applicable) if necessary.
An existing ATM QoS profile can be edited or deleted only 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 CEMF query against the profile name (for details, refer to the Cisco Element Management Framework User Guide.)
Once you have removed a QoS profile from all interfaces, you can proceed to edit the fields in the ATM QoS Profiles Configuration window or delete the selected QoS profile.
Step 2 Go to Deployment > Delete Objects. The delete wizard appears.
Step 3 Click Finish to delete the selected object. A message appears, confirming successful deletion. Note that deletion fails if the QoS profile is being used.
The ATM QoS Profiles Configuration window contains two tabs: Profile and RxTx Parameters.
The Profile tab contains the following fields:
It is possible to select a Service Category that is not supported by the Cisco 7200/7400 Series Manager, such as ubr. However, this will be detected when an attempt is made to create the connection on the device and the operator will be informed.
Also, transmit (Tx) and receive (Rx) are both applicable to SVCs. Only transmit is applicable to PVCs.
The RxTx Parameters tab contains the receive and transmit parameters for the selected ATM QoS profile (see Figure 10-3). Note that only the transmit parameters are applicable to QoS profiles.
The RxTx Parameters tab contains three areas:
The Category area contains one field:
This area is not applicable to Cisco 7200/7400 Series Manager.
The Transmit Parameters area contains the following fields:

Note PVC and VCL are interchangeable terms in Cisco 7200/7400 Series Manager. |
To deploy a PVC on a main interface or a subinterface:
Step 2 Choose the template you want to use and select either Auto Named or User Named (for details on Auto Named vs. User Named, see the "Deploying Modules" section). Make sure your selection is highlighted in black before clicking Forward.
Step 3 Enter the number of Cisco VCLs you want to create.
Step 4 Enter a unique name (prefix and suffix) for the VCL (Cisco VCL 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, see the "Deploying Modules" section).
Step 6 Click Forward to proceed.
Step 7 Enter a Subscriber ID.
Step 8 Click Select. A new window appears. Navigate down the hierarchy until you find the interface you want to deploy the PVC under. Click the object to select it, then click Apply. You are returned to the window shown in Figure 10-7.
Step 9 Click Forward to proceed.
Step 10 Click Finish if the deployment summary information is correct. Click Dismiss to complete the deployment. The Deployment Wizard closes and the object is created under the selected interface.
To deploy an SVC object on a main interface:
Step 2 Choose a template, either an SVC with a CEMF endpoint, or an SVC with a non-CEMF endpoint. Click Forward to proceed.
Step 3 Enter the number of SVCs you want to deploy. Click Forward to proceed.
Step 4 Enter an SVC name. This name must be unique.
Step 5 Enter the Destination NSAP Address. This field appears only if you have chosen to deploy a non-CEMF endpoint.
Step 6 Click Forward to proceed.
Step 7 Click the first Select button. A new window appears. Navigate down the hierarchy until you find the interface that will be the local endpoint. Click the object to select it, then click Apply. You are returned to the window shown in Figure 10-12. If you have selected the CEMF endpoint option, you need to repeat this process for the second interface (remote endpoint) by clicking the second Select button.
Step 8 When you have selected the appropriate interfaces or subinterfaces for both endpoints (if applicable), click Forward to proceed.
Step 9 Click Finish if the Deployment Summary information is correct. Click Cancel to stop the deployment. The Deployment Wizard closes and the object is created under the selected interface.
Now you can apply the ATM QoS Profile you created earlier to a PVC or an SVC.
To view the ATM Connection QoS Configuration window:
Step 2 Choose the related chassis, module, interface, and connection (PVC or SVC) from the list box on the left side of the window.
This connection should be the PVC or SVC that you want to apply the ATM QoS profile to. Any current ATM QoS profiles applied to the selected PVC or SVC appear on the tabs on the right side of the window.
Step 3 Choose Edit from the toolbar. Go down to the Apply Profile menu option. A list of ATM QoS profiles appears. Click the named ATM QoS profile you want to apply. After you apply the profile, a status line appears in the lower left corner of the window, telling you whether or not the profile was applied successfully.
The information for the selected new profile appears in the tabs on the right side of the window.
The PVC Configuration section covers the following topics:
To view the PVC Configuration window:
Step 2 Choose the chassis, module, interface, and Cisco VCL (PVC) from the list boxes on the left side of the window.
Step 3 Enter the relevant values in both tabs, using the drop-down list boxes and data entry boxes. For a detailed description of the fields in both tabs, see the "PVC Configuration WindowDetailed Description" section.
Step 4 Click the Save icon to save the changes made.
You can connect or disconnect a PVC in the Layer 3 Configuration tab.
Connecting a PVC creates the PVC on the device, which makes it a real, working connection. The PVC is also commissioned at this time, which allows you to manage configuration and status details.
Disconnecting a PVC disconnects entirely from the device.
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:
Once you have decommissioned a connected PVC, you might want to commission it again, to reestablish management on the connection. To recommission a PVC, click Connect and the connection is commissioned.
The ATM VCL Configuration window (see Figure 10-15) contains two tabs: Configuration and Layer 3 Configuration.
The Configuration tab (see Figure 10-15) contains four areas: VPI/VCI, Traffic Information, Encapsulation Parameters, and OAM Information.
