Supported Technologies

Table 8-1 lists the technologies supported in this version of the product.

Cisco ANA provides different levels of support for each technology. The fact that a specific technology is listed in Table 8-1 does not imply that every aspect of every relevant standard is represented and supported. For details on the level of support provided for each technology, see the description for that technology in the chapter listed in the "Chapter Reference" column.

In addition to supporting specific technologies, Cisco ANA:

•Relies on several abstract modeling components used throughout product. For details, see Chapter 34, "Common Components."

•Uses common approaches to discovering and modeling network topologies. For details, see Chapter 35, "Cisco ANA VNE Topology."

Networking-Related IMOs

Networking-related Information Model Objects (IMOs) represent the networking aspects of a network element (NE). The two major categories of IMOs are termination points and forwarding components.

Termination Points

Termination points represent the endpoints of a connection. A termination point may represent a physical endpoint (for example, a port connector) or a connection endpoint (such as an ATM layer of a port). A connection endpoint can also be called a network interface.

Termination points are related by containment. The following attributes express those containment relationships:

•Contained Connection Termination Point—Points to all upper-layer termination points bound to this termination point.

•Containing Termination Points—Points to all lower-layer termination points to which this termination point is bound.

The relation between termination points may represent one of the following:

•Type of hardware. For example:

A SONET/SDH port with a fiber-optic connector is represented by two IMOs:

–Port Connector IMO—Represents the fiber-optic connector.

–SonetSdh IMO—Represents the SONET/SDH port.

The Port Connector IMO contains the SonetSdh IMO. This containment relationship is represented as follows:

–The Port Connector IMO points to the SonetSdh IMO with the Contained Connection Termination Point attribute.

–The SonetSdh IMO points to the Port Connector IMO with the Containing Termination Point attribute.

•Configuration. For example:

An Ethernet port configured with an IP address (and, optionally, other network-layer attributes) is represented by two IMOs:

–Ethernet Interface IMO—Represents the Ethernet layer of the port.

–IP Interface IMO—Represents the network-layer aspect, including the IP address configured on the port.

The Ethernet Interface IMO contains the IP Interface IMO. This containment relationship is represented as follows:

–The Ethernet Interface IMO points to the IP Interface IMO with the Contained Connection Termination Point attribute.

–The IP Interface IMO points to the Ethernet Interface IMO with the Containing Termination Point attribute.

•State. For example:

An active PPP connection running on top of ATM VC is represented by two IMOs:

–Atm Vc IMO—Represents the ATM VC.

–Vc Based Encapsulation IMO—Represents the PPPoA encapsulation.

The Atm Vc IMO contains the Vc Based Encapsulation IMO. This containment relationship is represented as follows:

–The Atm Vc IMO points to the IP Vc Based Encapsulation IMO with the Contained Connection Termination Point attribute.

–The Vc Based Encapsulation IMO points to the Atm Vc IMO with the Containing Termination Point attribute.

---

Note The relationship between termination points may be restricted to specific termination point types, based on how the technology is implemented. For example, a physical layer IMO may not contain an IP Interface IMO, which represents the network layer interface.

---

Forwarding Components

Forwarding components represent components that perform some type of forwarding function between termination points. Among other things, forwarding components can represent routing, bridging, and switching components in the NE.

Each forwarding component has a logical association with the termination points for which it does the forwarding. This relationship is expressed by the logical associations attribute of the forwarding component IMO. An example of such a relationship would be the logical association between an IVcSwitchingEntity IMO representing the ATM/FR switching fabric and the IAtm/IFrameRelay IMOs representing the relevant ATM/FR ports.

---

Note The support level of each network technology can be varied. The support level is reflected in its related IMOs with their attributes, network topology, and fault and alarm correlation, as described in each of this Guide's technology chapters and in the Common Components chapter.

---

The polling intervals for the relationship between the termination points, as well as between them and the various forwarding components, are more complex than can be uniformly expressed, so they are marked as Not Applicable (N/A) in their corresponding Polling Interval columns. This applies to Containing Termination Points, Contained Connection Termination Points, and Logical Sons attributes of an IMO.

Scheme Values

The Scheme column of each IMO table can have the following values:

•IPCore

•Product

•Any

•N/A—This value is populated as part of the creation of the IMO, not by polling the device.

Polling Interval Values

The Polling Interval column of each IMO table can have the following values:

•Status

•Configuration

•System

•Topology Layer 1 (Topology L1)

•Topology Layer 2 (Topology L2)

•N/A—Not every property has a polling interval. Some properties are created from the results of multiple queries, and there is no specific polling for them.

For more information about polling intervals, see the Cisco Active Network Abstraction 3.7 Administrator Guide.
