Managing ATM Connections
This chapter describes the ATM connections supported by the Cisco 12000 Manager (C12kM) application and guides you through the creation and configuration of these connections.
The Cisco 12000 series internet routers use both terminating Permanent Virtual Circuits (PVCs) and Switched Virtual Circuits (SVCs). A PVC is modeled in C12kM as an object that is deployed beneath an interface. The interface acts as the endpoint. An SVC is modeled in C12kM as an object that is deployed beneath an interface, but it has two endpoints. The remote endpoint can either be a non-Cisco Element Management Framework (Cisco EMF) endpoint (which means it is outside Cisco EMF) or a Cisco EMF 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.
Note
Fields appear on various windows within the C12kM application that are not applicable. In such cases these fields should be ignored. Information detailing the fields that should be ignored are provided in the appropriate sections.

ATM Connections Supported by C12kM
ATM connections are modeled in C12kM as objects that are deployed beneath an ATM interface. C12kM supports two types of ATM Connection: Terminating Permanent Virtual Circuits (PVCs), and Switched Virtual Circuits (SVCs).
Note
Both types of ATM connection are now discussed in greater detail.
PVC Connections
A PVC is a permanent logical connection that must be configured from source to destination. PVCs save bandwidth associated with establishing a circuit when a virtual circuit must exist all the time. You can deploy a PVC (which creates the PVC within Cisco EMF), apply an ATM Traffic Descriptor to the PVC, then create the connection on the device. Deploying and creating a PVC creates a cross-connection within one device.
Terminating PVC Connections
A terminating PVC connection object is modeled in C12kM as a single object deployed beneath a ATM interface (see Figure 12-1). The ATM interface acts as the end point.
Figure 12-1 Terminating PVC Connection
SVC Connections
An SVC is modeled in C12kM as an object deployed beneath two interfaces (see Figure 12-2). The remote endpoint can be a non-Cisco EMF endpoint (that is, outside Cisco EMF)) or a Cisco EMF-endpoint (that is, within Cisco EMF). Deploying and creating an SVC creates a connection between the outgoing port (or source) on one device and the incoming port (or destination) on a second device.
Figure 12-2 SVC Connection
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. The SVC saves bandwidth as opposed to the PVC, but is generally slower in operation.
Launching the ATM Connections Windows
Table 12-1 displays each object type that can be used to open the C12kM windows that allow you to upload, create and configure ATM connections. For example, the ATM QoS Profiles Configuration window can be launched from a Site, Shelf, Chassis or Module object, but cannot be launched from an Interface object.
ATM PVC Connection Synchronization
The idea behind the ATM PVC Connection Synchronization is to provide a mechanism to update the ATM connection details stored in the Cisco EMF from the current configuration on a device. This is necessary if the device is updated, for e.g., if a new ATM connection is added (or removed) then the Cisco EMF should be able to re-read from the device and update the Cisco EMF by creating new objects if necessary.
The Synchronization process is initiated in the following circumstances:
•
•
•
The policies that are available for ATM connection synchronization are described in the Table 12-2.
Table 12-2 ATM Connection Synchronization Policies
Normal (default policy with C12kM)
0
Device_is_Master
1
CEMF_is_Master_After_First_Sync
2
Normal Policy
The Normal policy creates new PVC connection objects in the EM, for the connections available on the device. In case connection object that is available in the EM is removed from the device, then the normal policy moves the connection object into the decommissioned state during the next synchronization. If the same object with the same configuration details is again added to the device, the normal policy identifies the object and moves it to the normal state. However if a new connection object is added to the device with different configuration details, then the normal policy creates the connection object in the EM and moves it to the normal state. The ATM Connection synchronization never deletes any ATM connection object.
Syntax for Set:
cd <CEMF_ROOT>/bin
./objectUtilsTestRig setIntValue "ComponentManaged:<absolute-path of the chassis>" ciscoPlatformCon:CiscoChassis-MIB.DeleteConnections 0(for policy information, refer Table 12-2)
./objectUtilsTestRig setIntValue "ComponentManaged:<absolute-path of the chassis>" ciscoPlatformCon:CiscoChassis-MIB.DeleteConnections 1(for policy information, refer Table 12-2)
./objectUtilsTestRig setIntValue "ComponentManaged:<absolute-path of the chassis>" ciscoPlatformCon:CiscoChassis-MIB.DeleteConnections 2(for policy information, refer Table 12-2)Syntax for Get:
./objectUtilsTestRig getAttrValue "ComponentManaged:<absolute-path of the chassis>" ciscoPlatformCon:CiscoChassis-MIB.DeleteConnectionsDevice_is_Master
This setting specifies that the Cisco device is the reference point for PVC creations and deletions. C12kM will sync up to the device. If a connection is present on the Cisco device but not in C12kM, C12kM will create the connection. If a connection is absent on the Cisco device but present in C12kM, C12kM will delete the connection.
CEMF_is_Master_After_First_Sync
This setting specifies that C12kM is the reference point for PVC creations and deletions, after the first synchronization. The device syncs up to the C12kM for information about PVC settings. If the connection is present in C12kM but not the Cisco device, C12kM creates the connection in the Cisco device. If the connection is absent in C12kM but present in the Cisco device, C12kM deletes the connection from the Cisco device.

Uploading Existing ATM Connections and QoS Profiles
This section describes how to upload existing ATM connections and profiles (previously configured on a Cisco device) into the C12kM application. Uploading saves time and effort re-configuring ATM connections and profiles that already exist on the device.
When you upload PVCs, any corresponding ATM QoS profiles are also uploaded. 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 within C12kM. Existing ATM connections and QoS profiles are uploaded from the ATM Connection Upload window.
Note
The Uploading PVCs and ATM QoS Profiles section covers the following areas:
