Cisco Systems 3.5 manual Defining VNEs, Admin and Oper Mode VNE Status

Page 105

Managing AVMs and VNEs

While in maintenance mode (temporary state) a VNE:

Does not change state on its own, unless the user explicitly (manually) switches the VNE back to active state.

Never polls the device.

Does not report any alarms, including device reachability.

Maintains any existing links.

Does not fail on verification requests.

For more information about maintenance mode, refer to page 104.

6.7.2Admin and Oper Mode VNE Status

The table below describes the status of a VNE depending on the Admin and Oper modes, as displayed in the Status column of the VNEs table. The Admin mode is the administrative instructions that are sent to the VNE. The Oper mode is the actual status of the VNE, for example, Up.

For example, if the user starts the VNE, the Admin status is Up but the Oper status is Down and has not started yet (because the Server is busy), the status is Starting Up. If the VNE is Up and running and the user stops the VNE, the Admin status is Down but the process is not terminated immediately, the status is Shutting Down.

6.8Defining VNEs

The user adds and defines a new VNE for the system using Sheer DNA Manage; this VNE corresponds to a Network Element (NE) and should only be added to the system once. As the VNE loads, Sheer DNA starts investigating the NE and automatically builds a live model of it, including its physical and logical inventory, its configuration, and its status.

When adding a new VNE, Sheer DNA creates the registry information of the new VNE in the Sheer DNA Unit. The newly created VNE has an administrative status of Down and uses the default community strings and polling rates. The VNE inherits these properties from the configuration record that corresponds to the device type.
