To use this MIB module, it is essential to understand the provisioning model employed in the MGX 8800 Series products. This provisioning model is designed for the multiple types of services such as Frame Relay, circuit emulation, voice, and so forth.
The connection termination points are termed endpoints. These endpoints derive their characteristics from the type of service they handle. Thus, Frame Relay endpoints are characterized by a Frame Relay identifier (DLCI) and the committed frame rate. The endpoints can also terminate an ATM interface.
The connection between these endpoints is a ATM Switched Virtual Circuit (SVC). The routing of a connection within an ATM network is handled by a network controller, for example, Private Network-to-Network Interface (PNNI).
From a user perspective, the endpoint is identified by either physical entities, for example, node name, shelf, slot, or physical line, or logical entities, such as a DLCI in a Frame Relay module, a T1 slot number in a voice module, or a VPI/VCI in an ATM module.
We term the above identifiers as user addresses. There is yet another set of addresses that defines the endpoints within an ATM network. This is the address of the endpoint, as known to the network controller and hence termed network address. The network address is assigned by the switch when a user provisions an endpoint. The network address is mandatory for routing a connection. The network address in this ATM network is a combination of an Network Service Access Point (NSAP) address (a 20 octet number uniquely identifying a logical interface) and a VPI/VCI within this interface.
In a switched network, there is always a calling and a called party. Likewise in the ATM network, one endpoint is responsible for setting up the connection (making a call). This endpoint is termed the master endpoint, the other one being the slave. To route a call from the master to slave, the master endpoint needs to know the network address of the slave endpoint. And this information needs to be conveyed when provisioning a master endpoint. This imposes a sequence in provisioning a connection.
1. The Network Management System (NMS) adds the slave endpoint. The slave endpoint's user address is specified during the add operation. The switch assigns a network address to this added endpoint.
2. NMS gets the slave's network address from switch.
3. NMS adds the master endpoint. The master's user address is specified, along with the slave's network address.
4. If both the endpoints are added, SPVC provisioning is deemed successful. The routing of the connection takes place only after the master endpoint is added.

Max-Access: not-accessible
Status: current
none
cwaChanVci
Unsigned32 (0..65535)

cwaChanIdentifier
Unsigned32 (0..4294967295)
Represents a RESOURCE at the switch that has been assigned for this connection (identified by cwaChanVpi and cwaChanVci). An example of this resource is the LCN/GLCN used by the switch. Another example is a record number assigned for this connection in a database of records.
When a connection gets deleted, this resource gets released into a free pool. When a new endpoint is added (different cwaChanVpi and cwaChanVci), the switch reassigns this resource.
Thus, all connections in a switch would have a unique cwaChanIdentifier. Since the number of resources in the switch is a lesser subset compared to possible combinations of ifIndex, VPI, and VCI, this number serves as a quick reference index between the switch and the NMS.
This is especially useful during the configuration upload of connections from the switch to the NMS.
Max-Access: read-only
Status: current
none
cwaChanUpload Counter
Unsigned32 (0..4294967295)
Tracks the number of configuration changes that happen on a cwaChanIdentifier. The upload counter is associated only with the cwaChanIdentifier and not with the connection itself.
This counter is used by the NMS to determine if a connection configuration had been modified and requires an upload. This functionality is conventionally achieved by time stamping using a time-of-day clock. However, in switches where time-of-day clock is not available, a scheme is used.
The upload counter is incremented, when one of the following takes place:
•Assignment of connection to a cwaChanIdentifier. This happens when a connection is added and assigned this cwaChanIdentifier.
•De-assignment of a connection from a cwaChanIdentifier. This happens when a connection is deleted and the cwaChanIdentifier resource is released.
•When there is a configuration change completed to the connection that is associated with this cwaChanIdentifier.
•In a new system, a unutilized resource (cwaChanIdentifier) has a counter value of zero. When a connection is added to this cwaChanIdentifier, the counter is incremented, and is further incremented for any of the above operations. When a connection is deleted the value of this counter is incremented and preserved until a new connection gets associated with this cwaChanIdentifier.

cwaChanStats Enable
TruthValue
Limits imposed by software or hardware implementations can restrict the amount of statistical data that can be maintained in a physical entity. For example, a service module. Therefore, there is a need to restrict statistics collection to a smaller subset.
This object serves the purpose of enabling or disabling statistics collection on a per connection basis. In implementations which do not have such limitations, this object is set to true(1) for all connections.
Max-Access: read-create
Status: current
false
cwaChanCCEnable
TruthValue
Enables or disables Continuity Check (CC) on a connection endpoint. When continuity check is enabled on an endpoint, the endpoint anticipates Operation, Administration, and Maintenance (OAM) CC cells from its peer endpoint. OAM CC cells are sent when the peer endpoint does not have traffic cells to send. If the connection is idle and this endpoint has not received OAM CC cells for a period of 3.5 +/- 0.5 seconds, it declares continuity failure.
This object serves to administratively control the CC feature. Typical implementations (of this feature) can choose to ignore this control or impose other conditions to actually enable CC cell flow. However, if this object is set to false(2), this feature is disabled.

cwaChanTestType
CiscoWanLpbkTypes
Configures an endpoint in loopback. To configure a destructive loopback, this object needs to be set to destructive(2). The direction in which this destructive loopback needs to be effected is specified using the cwaChanTestDir object.
To deconfigure destructive loopback, this object needs to be set to noLpbk(1).
To configure a non-destructive loopback, this object needs to be set to nonDestructive(3). The direction in which this non-destructive loopback needs to be effected is specified using the cwaChanTestDir object.
Non-destructive loopback gets deconfigured automatically at the switch after a certain timeout. However, if there is a need to abort a non-destructive loopback, a set operation on this object should be performed with a value noLpbk(1). Attempting to set a channel in loopback, when one is already in progress results in a failure of the set operation (with appropriate error code).
