Checking VNE Connectivity and Communication Status
Figure 3-5 VNE Status Details Window
The VNE Status Details window provides this information about the VNE:
• Its management connectivity state, which has to do with how the VNE was configured
• The protocols the VNE is using to communicate with the device and the status of each
• Whether the device is generating syslogs or traps
In the Management State area, if the Reduced Polling field is true and the Investig ation State is Currently
Unsychronized, refer to the information in the topic Performing a Manual Device Poll, page 3-18.
This information can be useful to users who are troubleshooting d evice problems. For more information
about the VNE Status Details window, see the Cisco Prime Network 4.0 Administrator Guide.
Performing a Manual Device Poll
The VNE settings determine how often a VNE polls a device to update its model. Some VNEs use the
reduced polling (also called event-based polling) mechanism. A reduced polling VNE polls the device
when a configuration change syslog is received and immediately updates the VNE information
accordingly. In other words, updates are driven by incoming events.
The risk with reduced polling is dropped events. But if an event is dropped, the network element shows
a Currently Unsynchronized investigation state. If you notice this VNE state, initiate polling by
right-clicking the element and choosing VNE Tools > Poll Now.
For more information about reduced polling, see the Cisco Prime Network 4.0 Administrator Guide.
