6.11Changing the VNE’s State

Sheer DNA Manage enables the user to start or stop a VNE or move a VNE to maintenance mode. Starting the VNE adds the VNE to the server bootstrap. Stopping the VNE removes the VNE from the server bootstrap.

During normal operation, NEs often undergo maintenance operations and planned outages (software upgrades, hardware modifications, cold reboots and so on). The Sheer DNA platform supports such maintenance operations without affecting the overall functionality of the active network. Neighboring VNEs do not generate alarms that are related to links to or from the maintained VNE.

While in maintenance state (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.

The VNE blocks all provisioning flows that run through the VNE. A device in maintenance state can be disconnected and/or restarted, and this does not result in link down alarms. Upon restart, the VNE receives only persistent information, and returns to its latest known configuration, the topology links are renewed automatically.

A VNE in maintenance state appears in Sheer NetworkVision displaying this icon:

To change the VNE’s state

1.Select the DNA Servers branch in the Sheer DNA Manage window. The DNA Servers branch is displayed.

2.Expand the DNA Servers branch and select the required AVM sub-branch in the Tree pane.

3.Select the required VNE in the in the VNEs Properties table in the Workspace.
