Prime Network Vision Status Indicators
More than one management state can occur at the same time. For example, a single overlay icon can be
displayed, reflecting the device status based on the following priorities:
Unsupported > Discovering > VNE/Agent Unreachable > Device Unreachable > Partially
Discovered > Operational.
For more information about each of these states and how to troubleshoot any issues, see the Cisco Prime
Network 4.0 Administrator Guide.
Discovering The VNE is building the model of the device (the device type was found and is
supported by Cisco Prime Network). A VNE remains in this state until all device
commands are successfully executed at least once, or until there is a discovery
timeout.
Operational The VNE has a stable model of the device. Modeling may not be fully complete, but
there is enough information to monitor the device and make its data available to other
applications, such as activation scripts. A VNE remains in this state unless it is
stopped or moved to the maintenance state, or there are device errors.
None
Currently Unsynchronized The VNE model is inconsistent with the device. This can be due to a variety of
reasons; for a list of these reasons along with troubleshooting tips, see the topic on
troubleshooting VNE investigation state issues in the Cisco Prime Network 4.0
Administrator Guide.
Maintenance VNE polling was suspended because it was manually moved to this state (by
right-clicking the VNE and choosing Actions > Maintenance). The VNE remains in
this state until it is manually restarted. A VNE in the maintenance state has the
following characteristics:
• Does not poll the device, but handles syslogs and traps.
• Maintains the status of any existing links.
• Does not fail on VNE reachability requests.
• Handles events for correlation flow issues. It does not initiate new service alarms,
but does receive events from adjacent VNEs, such as in the case of a Link Down
alarm.
The VNE is moved to the Stopped state if: it is VNE is moved, the parent AVM is
moved or restarted, the parent unit switches to a standby unit, or the gateway is
restarted.
Partially Discovered The VNE model is inconsistent with the device because a required device command
failed, even after repeated retries. A common cause of this state is that the device
contains an unsupported module.
To extend Cisco Prime Network functionality so that it recognizes unsupported
modules, use the VNE Customization Builder. See the Cisco Prime Network 4.0
Customization Guide.
Shutting Down The VNE has been stopped or deleted by the user, and the VNE is terminating its
connection to the device.
Stopped The VNE process has terminated; it will immediately move to Defined Not Started. None
