Support Information for Generic Devices


This chapter contains support information for Virtual Network Elements (VNEs) that manage Generic devices in Cisco ANA Version 3.6.6. For more information about the objects and attributes described in this chapter, see the Cisco Active Network Abstraction 3.6.6 Technology Support and Information Model Reference Manual.

This chapter contains the following topics:

Understanding the Generic VNE

Supported Technologies on Generic Devices

Understanding the Generic VNE

The generic VNE can be used to model any NE that is not currently supported by Cisco ANA. The generic VNE provides a basic level of network management that provides information such as the physical interfaces available on the device and their status, rudimentary logical modeling, and parsing of basic traps.

The generic VNE models NEs using SNMP MIB2, which is the most generic and widely used management interface. The generic VNE does not consider the device vendor, device type, or software version of the NE that it models.

Physical Inventory Model

The generic VNE uses a static model for the device chassis. The rest of the physical inventory is modeled using the ifTable. Since modules are not modeled, the generic VNE creates a single generic module on which all of the physical interfaces reside.

Table 10-1 describes which MIB tables are used to model the physical inventory components that are supported by the generic VNE.

Generic VNE—Supported Traps

The generic VNE can parse the standard MIB2 traps listed in Table 10-3.

linkUp

The generic VNE can identify traps, but it cannot correlate them. This is because the generic VNE does not include the model entities required by higher trap parsing levels.

For example, if Cisco ANA receives an mplsTunnelDown trap from a device modeled with the generic VNE, Cisco ANA can identify the Tunnel Down trap, but it cannot perform correlation on the trap. The reason is that the generic VNE does not investigate tunnels, which means that there is no Device Component in the model to which Cisco ANA can attach a correlation flow.

Generic VNE—Supported Events

The generic VNE supports the service events listed in Table 10-4.

Limitations

The generic VNE uses MIB2 to cover the widest possible range of NEs. Although MIB2 is a widely accepted industry standard, most network equipment vendors augment MIB2 with other Management Interfaces such as private MIBs, Telnet, XML, and so on. In addition, different vendors sometimes have different implementations of standard MIBs. As a result, even the limited model created by the generic VNE is dependent on the vendor's adherence to general network management standards.
